ONEDAY BRAKE ROLLER REPAIR KIT
CLASS 5 INSTRUCTIONS
TK/COM34VC1
EXTRA HEAVY DUTY
This kit has been specially developed to produce a hard & durable surface on Commercial Brake Testing Rollers
that are subject to Extra Heavy Usage. The kit contains enough material for 1-4 commercial brake rollers & can
be used for patching or fully replacing the existing coating. Stored material will keep at least a year between
jobs, usually much longer. Oneday kits build up two thick coats to bond very coarse grit. This is then sealed
using a solvent free sealer. Kits are also suitable for applying Slip-Resistant Coatings to metal, concrete, wood,
stone, brick, and other surfaces where the very coarse nature of the coating is necessary.

HEALTH AND SAFETY
With simple precautions the chemicals used before mixing are straightforward to use. (See Health & Safety
Sheet.) Once the Bonding Agent and Hardener have been mixed and gone hard, the high-friction surface is
completely safe and remains so. For your own safety, please observe the following simple precautions during
application. As with all chemicals, keep them off your skin by using the gloves supplied, and avoid getting them
on clothing which touches the skin, such as cuffs. Ensure adequate ventilation. Keep them out of your eyes don’t splash. Avoid any chance of swallowing by not smoking, eating, or drinking whilst working, and wash your
hands afterwards. If you do get any on your skin, clean it off immediately, using a solvent-free hand cleanser.
For splashes in the eyes, wash with lots of water, and seek medical attention, if necessary. Keep chemicals away
from food and children.
IMPORTANT POINTS
In cold weather, if possible, keep the rollers (or area being coated) at 15-21oC (60-70oF) throughout the work.
Curing will work down to below 5oC, but more slowly. Surface moisture on cold, damp days can reduce adhesion.
Screen to prevent draughts, & heat with infra red, space heaters etc. Tube heaters, lead lights etc in the pit will
help overnight. Remember, it’s the roller or floor temperature that matters, not the air temperature!
Store the kit in a warm room before use.
Avoid starting with cold or hot chemicals - 12 to15oC is best for speed & pot life. Use a bowl of water to adjust.
For periodic brush cleaning, use cellulose thinners, epoxy thinners, or trichloroethylene. The Surface or Rollers
MUST NOT BE USED until the coating is HARD.
To check, make a test piece (metal or wood, say 2”x2”) when the coating is complete. Put a ‘dab’ of coating on it
(do not grit) and leave next to the gritted area. Test by first thumb pressure and then with a screwdriver before
using. When hard, the coating still continues to gain strength over several days, so build up the work load. To
save grit, make a simple catcher. Take a piece of cardboard the width of the pit and fold and tape the lower end
to form a trough. Remove the side plates on Brake Rollers, & fit the catcher. If an area is being coated, obtain a
long brush-type draught excluder as used on the bottom of internal doors. Half provides an excellent levelling
brush.
After a very long period of storage, (several years), the Bonding Agent may stiffen. If so, place the tub in hot
water (60oC), and stir until liquid again.

DETAILED INSTRUCTIONS
Stage 1: SURFACE PREPARATION
It is extremely important that the surface is prepared properly before applying coating. A shot blasted
surface is ideal, preferably using chilled slag. A needle descaler or angle grinder is also effective. Remove
dust
with a dry brush, hot air blower or vacuum. After any degreasing use an angle grinder to remove a final thin
surface layer of metal & expose clean material. Any rust pitting must be cleaned using either a hand held
shot
blaster or fine wire brush. Cleanliness & roughness are essential to maximise bonding.
Stage 2: MIXING THE BONDING AGENT
Wear gloves. Ensure ALL surfaces to be coated are FULLY prepared and CLEAN BEFORE mixing chemicals.
Stir Bonding Agent before use. Take one measure (brown) of Bonding Agent (50ml), and one measure
of Hardener (25ml) and mix well in a paper cup, using one of the spatulas supplied. The correct mixture is
important, so make sure the measures are filled and emptied completely. Use separate spatulas to remove
the last of the Bonding Agent & Hardener measures. Mix in a measure (100ml white) of Thickener until
smooth. This may need increasing slightly in hot weather or decreasing in cold. Adjust after the first mix.
Once mixed, the material must be used within 15-20 minutes.
Stage 3: APPLYING THE 1ST COAT
Brush an even, smooth, coat onto the surface. If carrying out a repair, brush to the edge of, but not on top
of the existing coating. The coating thickness should be thicker than that of domestic paint, and should
be inspected carefully for thin or thick areas, which should be corrected. Brushing is more difficult than for
paint. If runs occur when the roller is turned, more thickener is needed. If brushing is almost impossible use
less. When a convenient area has been coated, lightly brush in both directions to further even the thickness.
Dip the brush in cleaner periodically, (see previous page), and wipe after each mix is applied to prevent it
hardening. Apply Ceramic Grit frequently, say after every two mixes, or complete roller. This ensures the
strongest bonding. (For non-slip coatings only make a test piece (above) from final Bonding Agent mix.)
Stage 4: APPLICATION OF THE 1ST CERAMIC GRIT COATING
For Rollers, fit the grit catcher (above). Apply an excess of grit to the coated area, making sure the surface is
fully coated after ‘settling’. Apply 2nd coat as soon as first is stiff for maximum intercoat bonding.
Stage 5: MIXING & APPLYING THE 2ND BONDING AGENT COATING & GRIT
When the first coat has stiffened, mix & apply a further coat (repeat sections 2, 3 & 4). Application of the final
grit coat requires care. Too little results in grit ‘sinking’, leaving insufficient on the surface for correct grip.
Gently broadcast grit over the surface ensuring complete coverage. Allow a little time for the grit to settle in.
Following application, check for any spots with two light a coating, and carefully correct to ensure a heavy
coating of grit. Apply Sealing Coat as soon as 2nd coat is stiff for maximum intercoat bonding.
Stage 6: MIXING THE SEALING COAT
As soon as the first coat has stiffened, the Sealing Coat should be applied to ensure maximum stength.
Stir Bonding Agent Sealer (BL5) before use. (Measures previously used with BL1 are OK.) Take one measure
(50ml) of Sealer BL5) and one measure (25ml) of Hardener (H1) and mix well in a paper cup, using one of the
spatulas supplied. The correct mixture is important, so make sure the measures are filled and emptied
completely. Use separate spatulas to remove the last of the Sealer & Hardener.
Stage 7: APPLICATION OF THE SEALING COAT
Brush the Sealing Coat over the Ceramic Grit, ensuring an even coating, and making sure that the gaps
between the grit are filled without excess material being able to run. Make a test piece (above) from this
coat.
Stage 8: CURING
Allow the surface to cure for as long as possible (upto 16 hours at 65oF (19oC), longer at lower temperatures).
Where applicable brush off any excess Ceramic Grit and retain. When the TEST PIECE IS HARD, (see above)
the surface is ready for use. Allow the workload to build up as the surface continues to get stronger still for
up to a week.
