Safety Rules
1.1 For your own safety, read the HI-MACS® Fabrication
Guidelines manual before operating the different tools.
1.2 Earth tools. If a tool is equipped with a three-prong plug, it should
be plugged into a three-hole electrical socket. If an adapter is used to accommodate a two-prong socket, the adapter lug must be connected to a true earth ground. Never remove the third prong. 1.3 Remove adjusting keys and wrenches. Form the habit of checking
to see that keys and adjusting wrenches are removed from the tool before turning to "on".
1.4 Keep work area neat and clean.
1.5 Damp environment. No tools should be used in wet and damp
environments or exposed to rain. Keep your working area clean, dry and well ventilated, with adequate lighting.
1.6 Visitors and children. Keep all visitors and children at a safe distanc
from the work area. Make the workshop childproof by removing starter keys, putting master switches and padlocks out of reach.
1.7 Wear proper clothing. No loose clothing, gloves, neckties, scarves, rings,
bracelets or other jewellery that can get caught in moving parts should be worn. We recommend that you wear safety and non-slip footwear. Wear a protective hair covering to contain long hair as well as noise protectors.
1.8 Use visors, goggles. Standard glasses are not recommended as they do
not have impact resistant lenses.
1.9 Use a face or dusk mask if the cutting operation is dusty.
1.10 Secure work. Use clamps or vices to hold work. It is safer than using your
hands when operating a tool.
1.11 Keep your proper footing and balance. Do not overreach!
Fabrication Guidelines - March 2014 Fabrication Guidelines
Section 1
1.12 Use the right tools and do not force tools. Each tool has been
designed to work at a specific speed. The job will be safer and better done.
1.13 Tool maintenance. Maintain tools in top condition: sharp and cleanfor
the best and safest performance.
1.14 Tool disconnection. Disconnect tools before changing accessories such
as blades, bits, cutters or before servicing.
1.15 Accessories. Use all recommended accessories. Hazards may be caused
by the use of improper accessories.
1.16 Switch. Make sure the switch is in the off position before plugging in.
1.17 Unattended tools. Never leave tools running unattended – turn them
off until they come to a complete stop.
1.18 Alcohol, medication, drugs. Do not use any tools under the influence
of alcohol, medication or drugs.
1.19 HI-MACS® sheets should be carried by two persons, one at each end of
the sheet. Do not flex the sheets. Wear heavy duty gloves and if appropriate, use lifting straps.
1.20 Boxed products. Do not stack them too high. Stack them in a way that
is easy and safe to reach.
1.21 Alcohol, adhesives, other toxic or flammable products.

Keep them in a safe, dry and well ventilated area.

The basic HI-MACS® material is identical for every colour but it is important to note that darker and more heavily pigmented colours will show dust, scratches, haziness, marks left by hard water and other ordinary wear and tear more noticeably than lighter textured colours. Therefore colours marked with a * are less suitable for applications that are exposed to exten LOGO - Pantone 225C sive surface contact such as worktops located in heavy traffic area as an example. Due to spe-
cific characteristics and properties of the Marmo colours, which have a veined effect, special
consideration has to be taken into account with jointing and the use of coved up-stands. Vein-
ing may vary from sheet to sheet. There may be deviations between the illustrated and actual
colours owing to printing techniques. To receive the detailed availability, please contact us at
www.himacs.eu.
15 HI-MACS® colours are particularly suitable for outdoor applications because of their good UV-resistance. HI-MACS® offers a 5 years warranty on colours' UV resistance fora tolerance of ∆ E3 to ∆ E4 and loss of gloss over 40%, 10 years on colour leaching and 20 years on colour peeling, swelling or delaminating. The warranty is applicable after thefirst installation and is only valid for the sheet material; adhesives are excluded. The conditions for this warranty are based on practical experience and on-going tests.

Job Planning
8.1 Successful installation relies on accurate job planning, especially around
kitchen appliances.
8.2 Never position joints near cut-outs. (Fig. 1).
8.3 Never position a joint over dishwashers or heat producing appliances.
8.4 Keep joints away from internal corners, minimum distance of 50 mm
8.5 Wherever possible reinforce all joints (Fig. 3) with a strip of 12 mm
HI-MACS® at least 50 mm wide and angled to 45° along both long edges. Ensure that the strip covers the whole joint and spread adhesive over the complete surface of the strip. Clean joint smooth from underneath. 8.6 Inspect the site and check for anything that could interfere with fabricated
8.7 Check for unevenness in the wall (Fig. 4).
Fabrication Guidelines - March 2014 Fabrication Guidelines
Section 9
9.1 Cutting full size sheets of HI-MACS® should initially be carried out using a
panel saw, beam saw or table circular saw. Always remember to completely support the entire sheet during this operation. 9.2 Circular sawblades with triple chip teeth will provide the best possible result
(Fig. 1). A standard ø 300 mm saw blade should have 96 teeth and is best with a negative hook angle. (Fig. 2).
9.3 It is important to avoid stress fractures when sawing a HI-MACS® sheet;
this can lead to crack formation later. In the event of small chips and cracks appearing when cutting, ensure the edges are always dressed using a router or spindle moulder.
9.4 Never use hand held rip saws or portable jigsaws to cut sheets of HI-MACS®.
During on-site fabrication portable circular power saws can be used providing the edge is subsequently finished with a router. But the best and most efficient way is to use a router only with straight edge and/or template.
Fabrication Guidelines - March 2014 Fabrication Guidelines
Section 10
10.1 The machining of two pieces of HI-MACS® to create a seam joint can be
carried out in different ways. What is important however, is the quality of the machined edge.
10.2 The most reliable method is the "mirror cut" technique with a hand-held
router, which works by cutting both adjoining edges in one cut. Place the two pieces onto a seaming table (Fig. 1), leaving a gap of 9 mm between them and secure with either G clamps or screw clamps. Clamp a metal or compact straight edge to one of the pieces and to a strong and stable table. With a 12 mm double flute tungsten router bit fixed into your hand router, move the machine steadily in one direction away from your body and cut both sections at once. Maintain a slow steady pace without stopping. After cutting check that the joint matches perfectly and mark the mating position with a pencil line. 10.3 Another possibility is to machine each edge independently using a standard
workbench and straight edge (Fig. 2). First clamp the work piece to the bench and attach the straight edge to the sheet, so that the router will remove 1.5mm in total. Push the router at a slow steady pace without stopping. Repeat this exercise for the second piece and then check the accuracy of the joint. If the edges do not match then one or both of these edges will require re-machining. (Using a wavy profile router bit can avoid gauge difference between both work pieces).
10.4 After machining, both cut edges will require sanding with 150/180 grit
abrasive sandpaper and to be cleaned using denatured alcohol (or Acetone) with a white clean cloth or white industrial paper, in preparation for bonding.
10.5 The use of CNC cutting and nesting programs is becoming more and more
popular. Equipment, such as this, is becoming more and more efficient, especially for small serial production or individual requirements. Fabrication Guidelines - March 2014 Section 10 - 46 - Fabrication Guidelines
Section 10
10.6 When edges have been machined, sanded and cleaned, they are ready for
Bonding Seams
10.7 Before bonding, cover the tray beneath the seaming table with a transparent
tape in order to catch any overspill of adhesive (Fig. 1).
Seaming table tray
10.8 The sheets are to be clamped together using for example screw clamps. It
covered with transparent paper
will be necessary to fix small blocks to the sheet using hot melt adhesive. (Fig. 2). Additional working steps are needed till the work piece is finished.
10.9 Alternatively, sash clamps can be used, provided they are not over tightened.
10.10 Prepare the HI-MACS® adhesive system (see Section 016).
10.11 Apply tape at either end of the assembly prior to the application of adhesive.
10.12 Apply a continuous bead of adhesive along the entire part to be joined. (Fig. 3).
Reinforce the length of the joint and push the sheets together so that an even bead of adhesive is forced out from the joint.
10.13 Clamp the assembly but do not over tighten it, as this will cause weak joints
Blocks attached to the sheet
through starvation of adhesive.
10.14 Remove the clamps once the adhesive is fully cured and hard to the touch.
10.15 Remove excess cured adhesive with either a portable hand held router, set
on skis or a small block plane with a sharp blade. Whenever possible avoid the use of chisels.
10.16 Standard butt seams will remain a weak part of the assembly, therefore to
strengthen the joint, reinforce the underside with an offcut of HI-MACS® (Fig. 3). In cases where the joint could be affected by heat, it is strongly recommended to bevel (45°) the edges of the reinforced strip along the full length of the joint and to make a full adhesive film on the backside of the strip and to remove and finish off squeezed out adhesive till it is smooth.
10.17 Finish the joint by sanding it with 180/240 grit followed by 320 grit and
Scotch Brite (grey) or Superpad S/G 1200. Do not simply concentrate on joint alone as this will cause shallow depressions around the joint. 10.18 For detailed sanding instructions see Technical Bulletin

Cut-outs in HI-MACS®
12.1 Internal corner cut-outs for sinks, hobs and other accessories will always
be subject to higher stress and as such will require to be handled very accurately in accordance with the latest instructions given in these Fabrication Guidelines or additional Technical Bulletins.
12.2 Machine the cut-out using a CNC router or hand router and a template.
12.3 Always machine a radius around these corners and make the radius as
large as practical, (R >/= 8 mm). (Fig. 1).
12.4 Always ensure that there is a radius of R 3mm on both sides of the edge of
the cut-out (or using a profile router bit.: Titman no XC 341*12). (Fig. 2).
12.5 Do not position a joint or any glueline across any kind of hob.
12.6 For hob cut-outs the internal edge should be covered with self adhesive
Neoprene tape or Koawool tape and covered with self adhesive aluminium reflective tape (3M, tape no.: 425). This will prevent excessive heat build up and the potential risk of stress cracking.
12.7 Always leave a minimum of at least 3 mm space between the underneath of
the appliance and the edge of the HI-MACS® if possible (depending on the type of hob you may have to include a filling piece) (Largest diameter (Diameter of (Maximal use Fabrication Guidelines - March 2014 Section 12 - 52 - Fabrication Guidelines

Drop Edges & Downturns
13.1 Drop edges applied to sheets of HI-MACS® can create a multitude of design
13.2 One of the easiest ways to produce a drop edge is to simply stack layers of
HI-MACS® on the underside of the sheet. (Fig. 1).
13.3 Start by cutting strips which are slightly oversized and sand the underside
with 120 grit paper. Clean with denatured alcohol and white cloth.
13.4 Apply a sufficient amount of HI-MACS® joint adhesive to each of the strips
and smooth out using a wooden or plastic spatula.
13.5 Attach ‘A' style spring clamps every 70 mm to 80 mm and allow to cure
(approx. 45 min/+20°C). Ensure that, once the clamps have been applied, a reasonable amount of adhesive is forced out from the joint (Fig. 2).
13.6 When the adhesive is completely dry, smooth down the surface using a
circular table saw, then machine the required profile using a portable hand-held router or a table planer (Fig. 3).
13.7 Drop edges can sometimes be applied on edge, primarily for deeper
downturns. The best way to achieve this detail is to first rebate the underside of the sheet to a depth of approx. 1-2 mm (Fig. 4).
13.8 The rebate serves two functions, firstly it increases the bond strength and
secondly it minimizes the effect of uneven particle distribution.
13.9 As you would normally do, sand both the internal edges of the rebate and
the corresponding edges of the downturn with 150/180 grit paper, cleaned with denatured alcohol with a white cloth (Fig. 4).

Technical Bulletin 6
Fabrication Guidelines - March 2014 Section 13 - 53 - Fabrication Guidelines
Section 13
13.10 Apply a sufficient amount of adhesive and clamp edge in position with screw
clamps set 70 mm - 80 mm apart (Fig. 5).

13.11 Ensure that beads of adhesive are formed at both the internal and external
edge of the joint (Fig. 5). Once fully cured trim the overhang using a portable hand router, use a straight cutter with Nylon bearing attachment.

13.12 It is possible to create curved downturns to shaped counters, simply by
thermoforming the edges prior to bonding. Please refer to Section 020
for thermoforming techniques (but more time-intensive and limited in
terms of profile)
13.13 For internal/external corners, thermoforming will provide one solution,
alternatively simply stack up and bond sheets of HI-MACS® at theses corners and machine using a portable hand router.
13.14 When it comes to a ‘waterfall' edge, the top sheet will need to be rebated
while the edge will need grooving (Fig. 6).
13.15 Ensure that the connection between the rebate and the grove is neither too
tight nor too slack (Fig. 7).
13.16 Clamp the section together using sash clamps and allow the adhesive to
fully cure.
13.17 Machine the two edges using a purpose made router tool with a Nylon
bearing, working from the top edge (Fig. 7). Fabrication Guidelines - March 2014 Section 13 - 54 - Fabrication Guidelines
Section 14
14.1 Upstands or curved backsplashes can be created with either a square or a
coved detail at the internal joint (Fig. 1).
14.2 One method is to attach a square cut upstand to the top edge of a counter
with either HI-MACS® adhesive or a suitable colour matched silicone sealant.
14.3 A common alternative method is to form a coved upstand with an internal
14.4 Start by rebating the face side of the sheet which will form the counter, to a
depth of 2 mm x 25 mm wide (Fig. 2).
14.5 Cut a section of HI-MACS® 25 mm wide, this will form the internal cove.
The machine you must use is a 10/12 mm radius using an overhead router or spindle moulder (Fig. 3).
14.6 Cut a square section of HI-MACS® to the required height for the final

14.7 Rub down all edges to be bonded with 150/180 grit paper and clean with
denatured alcohol and a white cloth.

16.1 The final process in the fabrication of all HI-MACS® elements is to sand
(and/or to polish for special applications).

16.2 Under normal circumstances, begin by sanding the entire element with
120 grit paper. In instances where there has been no prior fabrication of the sheet, it is possible to start with 280 or 320 grit.
16.3 Always use dust extraction systems at all times when sanding, this will
help pick up loose particles of grit and prevent unwanted scratches.
16.4 Build up to finer and finer levels of grit size, taking care to clean down
between each change with a damp cloth. Finish with a 320 grit paper, followed by Superpad S/G 1200 from Jöst to reach a recommended semi-gloss level.
16.5 To improve the gloss level of the surface use 1200/1500/1800 wet or
dry Scotch Brite pads, or polishing pastes available from 3M or other manufacturers. High-gloss finish level is very high-maintenance and not recommended for normal use, but is ideal for art subjects. High-gloss finish Further information:
Technical Bulletin 4
Level is NOT covered under the 15 - year limited installed warranty program.

16.6 Keep the sander moving slowly in circles at all times, first in an East – West
direction then North – South (Fig. 1). Ensure that you use proper equipment, like a random orbital sander with a flat pad. For straight surfaces always use a hard pad. Soft or super-soft pads are recommended for curved surfaces.
16.7 Never concentrate on one specific area, particularly near joints, as this can
lead to dipping.
16.8 After each sanding step, wipe off dust, then start with the next step.
16.9 Be aware that some dark colours need more careful sanding than some
other lighter colours.

18.1 One of the main advantages of HI-MACS®, is that the surfaces can be
repaired in the event of an accident. Depending on the type of damage, a number of solutions can be used. 18.2 For scratches, it may well be possible to sand them out with Scotch Brite
pads, abrasive creams or even abrasive papers.

18.3 With small indentation marks it is possible to drill out the affected area and
fill the hole with HI-MACS® colour matched adhesive. Be sure to over fill the hole and try to eliminate any air pockets prior to curing. Once cured the adhesive can be sanded down in the normal way, however, the repaired area will need to be blended in with the existing work surface.
18.4 For larger areas of damage, particularly with the Granites and Sands, a
plug repair is a possible alternative solution. Router cutters are available from Titman or Trend (Fig. 1).
18.5 For major damage, such as cracks or burn marks, a 9 or 12 mm triangular
piece of HI-MACS® (same thickness as installed) will need to be fitted. Make a template as shown in Fig. 2, and clamp it to the surface around the damaged area. Machine out the section using a portable hand router. Using the same template cut another section from an off-cut of colour matched HI-MACS® sheet or, even better from the same sheet, to minimize any colour difference.
18.6 Bond the triangular spare piece with HI-MACS® adhesive and reinforce the
underside (Fig. 3).
18.7 To repair a broken joint, first machine a ‘V' groove down the entire length
of the crack.
18.8 Cut a square section of matching HI-MACS® so that when turned through
90°, it fits the groove (Fig. 4).
18.9 Apply HI-MACS® - adhesive into groove and push the square section home
until sufficient adhesive is forced upwards.

18.10 Once fully cured sand down the new section as normal. Ensure that the
seam has a reinforcement beneath prior to completion.

19.1 HI-MACS® can be moulded to a tight radius by means of heating. The oven
must heat the entire sheet for the thermoforming to be successful.
19.2 The sheets need to be heated to a temperature of 160 – 180°C, but should
never exceed 200°C.
19.3 Remove the protective film prior to heating.
Template
19.4 The minimum moulding radius for 12 mm HI-MACS® is approx. 45 mm
for Solids, Pearls and Sands and a minimum moulding radius for 12 mm HI-MACS® Quartz and Granite approx. 100 mm to 120 mm. Be aware that the darker the colour and the smaller the radius, the more whitening there may be.
19.5 The sheets should normally be heated for 15 to 30 minutes, depending on
batch (manufacture date), heating temperature and pre-heated oven. Rebating the reverse side in the area to be moulded can result in shorter heating times and smaller radius. Fig. 1.
19.6 Once heated to the required temperature remove workpiece with heat-
resistant gloves from the oven and place directly into a mould. Fig. 2. Male and female moulds are required. Allow heated material to shrink in the mould.
19.7 Leave the sheet in the mould until the sheet has cooled down, to approx.
60° C at least, (typically 20 – 40 minutes, depending on the material of Final Step
the mould). Always wear heat-protection gloves for this operation. 19.8 Never attempt any shock cooling as this can cause stress to the material.
19.9 Attempting to bend HI-MACS® at lower temperatures or shortening the
heating cycles will often result in "whitening" or cracking of the edge.
19.10 Normal sanding and finishing of the moulded edge can be carried out once
the sheet is fully rigid. Further information:

Use & Care
If you have searched long and hard for a superior quality, durable and tough material, we would like to congratulate you for choosing HI-MACS® Natural Acrylic Stone™. The material is hard-wearing, extremely repel ent to stains and is therefore very easy to look after. We would like to provide you with a few simple tips and hints for caring for your product so that you can enjoy its exceptional quality for many years to come.
General day-to-day stains
HI-MACS® is a completely homogenous material. As it does not have any pores, you
can simply and easily clean it with a damp cloth or sponge and a mild detergent.
You can also use a domestic scouring agent on all matt finishes. It is also useful to
wipe your surface occasionally with a scouring agent or wet sponge to retain the
even finish of your product.
Tougher stains
Tougher stains, caused by food colouring, tea or fruit juice can easily be removed
using a bleaching agent (do not leave in contact with the work surface for more
than five minutes). Clean the surface with a domestic all-purpose cleaner and rinse
with clean water. You can also use a scouring agent on matt finishes. Nail varnish
can easily be removed with nail varnish remover (acetone-free) or a scouring agent.
Acidic cleaning agents
A number of cleaning agents contain acids, such as methyl chloride or acetone. You
should avoid using these on a HI-MACS® surface. Should one of these products
accidentally come into contact with the material, as a precautionary measure you
should rinse the surface with soapy water to prevent any discolouring taking place.
HI-MACS® is an ecological material. Its mineral and acrylic composition, environmentally-friendly and virtually "waste-free" manufacturing process give it top marks in terms of "eco-friendliness." There can be no dirt build up where there are no joints. HI-MACS® can be simply and easily joined seamlessly.
Renowned hotels and restaurants rely on HI-MACS® because of its ease of care.
Fabrication Guidelines - March 2014 Section 20 - 62 - Fabrication Guidelines
Section 20
Hot objects
Hot saucepans or pots straight out of the oven or from the hob should not be laid
directly on the HI-MACS® surface. Place a mat or board underneath to prevent any
damage to your product.
If you pour boiling liquids into HI-MACS® sinks or basins, you should also pour in
cold water at the same time.
Burn marks
Small burn marks or marks caused by nicotine can simply be removed using a
scouring agent or an abrasive sponge. Should this give the high-gloss finish a matt
appearance, rubbing the surface with a scouring pad will quickly return it to its
high-gloss state.
Sharp objects
HI-MACS® copes effortlessly with the wear and tear of everyday life, however
pointed or sharp-edged objects can leave cuts or scratches on the HI-MACS®
surface. You can repair smaller cuts and scratches without too much trouble but
we recommend the services of a professional for especially deep cuts.
Quality and environmental awareness
All HI-MACS® products are manufactured in accordance with the ISO-9001 Quality
Process for Systems and Processes and the ISO 14001 Environmental Management
Standard.

3. HI-MACS® Colours and gloss finish of HI-MACS®
• the basic HI-MACS® material is identical for every colour but it is important to note that darker and more heavily pigmented colours will show dust, scratches, haziness, marks left by hard water and other ordinary wear and tear more noticeably than lighter textured colours.
• therefore colours marked with a * are less suitable for applications that are exposed to extensive surface contact such as worktops located in heavy traffic area as an example. Disclaimer colours (mentioned with a * on the brochure and on www.himacs.eu) are not covered by the present warranty.
• due to specific characteristics and properties of the Marmo colours, which have a veined effect, special consideration has to be taken into account with jointing and the use of coved up-stands. Veining may vary from sheet to sheet.
• applications using inappropriate gloss finish for the intended end use (as mentioned in the colours brochure or in any other HI-MACS® documentation) will not be covered under this warranty.
