Product Description
Sikalastic-520 Cool Coat Fibers IN is a 1-part, acrylic,
water based, elastic, cold applied liquid membrane
that can be applied directly from the container. It contains
addition of cross-linking polymers, special glass
micro fibres, pigments and advanced antifungal additive
that provides long lasting tough waterproofing
membrane. The high solar reflective index of the
membrane provides a heat reflective surface, minimises
surface temperature of the membrane and reduces
heat ingress keeping the interior of the building
cooler and thereby increasing thermal efficiency of the
building. The Product provides a seamless, smooth
waterproof finish which is resistant to UV exposure
and has elastic properties.
USES
Sikalastic-520 Cool Coat Fibers IN is used for:
Flat and sloping fully exposed roof structures
New construction and refurbishment projects
Waterproofing and renovation of old roof tiles
Waterproofing of external walls and sunshades
Roofs with numerous details such as penetrations,
drains, roof lights and complex geometry
Exterior coating for PVC water tanks
Sikalastic-520 Cool Coat Fibers IN is used on the following
substrates:
Concrete and cementitious substrates
Brick, masonry or renders
Unglazed clay tiles
Unglazed ceramic tiles
Asbestos or lime terraced roofs

Storage conditions The product must be stored properly in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 C and +30 C. Appearance / Colour Thick viscous liquid / White or Grey Other colours on request subject to minimum order quantity. Important: Applied colours selected from colour charts will be approximate. Important: For colour matching, apply colour sample and confirm selected colour under real lighting conditions. Important: When product is exposed to direct sunlight, there may be some discolouration and colour variation, this has no influence on the function and performance of the product finish.

Sikalastic-520 Cool Coat Fibers IN is an exposed system. Important: For larger application areas and high demanding applications, use a glass fabric reinforcement Sika Fabric-50 between the coats. For normal exposures, usage of Sika Fabric-50 is optional. Reinforcement (partial or total) must be used over dynamic cracks and joints. Important: For enhanced dirt pick up resistance and easy cleanability, above build up must be further coated with a thin layer of Sikalastic-10 Primer W
