Multithane ATC is single pack, aliphatic polyurethane
waterproofing top coat which has been formulated as a complimentary and
compatible top coat for Multithane UV and Duram 195. Aliphatic technology
provides greater UV protection, colour fastness and anti-chalking properties
and is designed to extend the life of exposed aromatic polyurethanes.
Multithane ATC forms a tough, flexible, seamless, highly UV stable, waterproof
coating. Multithane ATC meets the 'Green Star' environmental criteria.
Multithane ATC is primarily formulated as a highly UV
stable top coat over Multithane UV and Duram 195 to give greater long
term UV protection and colour fastness thereby extending the life and
performance of the waterproofing membrane.
Multithane ATC have been formulated as top coat over
Multithane UV and Duram 195.
The information contained in this product data sheet is
typical but does not constitute a full specification as conditions and specific
requirements may vary from project to project. The instructions should be
considered as a minimum requirement but the applicator or contractor must use
their skill, knowledge and experience to carry out additional works as may be
necessary to meet the requirements of the project. Specification for specific
projects should be sought from the Company in writing.
Suitable for maintenance foot traffic and not intended as
a general trafficable membrane.

Easily repaired and or maintained.
Odourless (subjective) when cured.
Formulated to provide long term protection.
Tar free- does not bleed.
Easy to apply.
Has good hydrostatic resistance.
Usually grey but can be made in other colours (minimum quantities apply)
Precautions in Use
Risk is considered low when properly used but precautions
on can, label and / or data sheets should be observed. Do not use in confined
areas with poor ventilation. Uncured product is flammable.
Priming and Surface Preparation
Good preparation is essential. Surfaces must be sound,
stable, dry, clean and free of dust, loose, flaking, friable material and
substances that may diminish adhesion.
As its main purpose is to be applied over cured
Multithane UV and Duram 195, it can be applied as follows:
OVER NEW MEMBRANES
Providing the existing membranes are clean, dry and that the Mutithane ATC is
being applied within 48 hours of applying the Mutithane membranes - no other
preparation is required. If the existing membranes have been contaminated refer
to 'TO EXISTING MEMBRANES' below.
TO EXISTING MEMBRANES
Multithane ATC may be applied to 'aged' Multithane membranes. These surfaces
should be dry, clean and free of dirt, dust and contaminants and should be
suitably cleaned depending upon the type of contaminant, e.g. if oil, then
clean with detergent, flushed and allowed to dry. The surface should be
wiped down with Duram Solvent to 'rejuvenate' the top layer, allowed to flash
off before applying the Multithane ATC.
Apply Multithane ATC to Multithane UV and Duram 195
membranes by brush, roller, broom and squeegee usually in one or two
coats at the rate of 3m2 per litre per coat, so that the minimum dry film
thickness is 300 microns.
The stated average coverage rate may vary depending upon
type, condition, porosity, texture of the surface and application technique.
Multithane ATC Top Coat: Generally, 3m2 per litre per
Generally grey. Can be manufactured in some other colours
but minimum quantities may apply.
Drying and Curing
Drying and curing of the product is affected by type,
dryness and porosity of the surface, temperature, humidity, ventilation,
climate conditions and application technique and therefore drying and curing
can only be given as a guide.
Generally Mulithane ATC is weather resistant within 6 to
8 hours with fulll cure within 24 hours.
Keep in cool, dry place away from heat, flame, combustible
material and all sources of ignition. Product contains flammable solvents.
Class 3 dangerous goods must be declared prior to transportation. Available in
5 and 15 lt pails.
Self life: 6 - 12 months in unopened container but best used within 6 months.
As this is a polyurethane some skinning of the product may occur. This should
be cut out and removed. Balance of the product will be suitable for use.
Avoid spills. They are difficult to clean particularly
off porous surfaces. Wet spills use a cloth and Solvent. Do not clean off
carpets as it is better to allow product to cure and then shave the carpet.
Equipment should be immediately cleaned with Solvent.
Tiling, Topping or Top Coating
Generally not covered, although membrane may be covered
with drainage cloth and pebbles, ensuring not to damage membrane.
Safety & Precautions
Multithane ATC is solvent based. The use of solvent
resistant gloves and goggles (against splashes) are recommended. Use in
ventilated areas. If spraying, in confined areas the use of self
contained breathing apparatus is recommended. If swallowed do not induce
vomiting, give plenty of water to drink. Seek urgent medical advice. If in
eyes, flush thoroughly with clean water, holding open lid to ensure any trapped
product may be flushed away. If on skin, remove contaminated clothing and wash
skin with soap and water. If inhaled, unlikely due to viscosity of the product,
remove person to fresh air and apply artificial respiration if required and
seek urgent medical attention. Product is flammable when wet. Keep away from
all sources of ignition. Ensure adequate ventilation. Vapours may collect in
low lying areas.
