Sikalastic®-530 Thermic AP
(former Davco K10 SolarTAC)
1-PART LIQUID APPLIED MEMBRANE FOR WALL AND ROOF WATERPROOFING WITH THERMAL INSULATING PROPERTIES
Sikalastic®-530 Thermic AP is a 1-part, acrylic, water based, elastic, cold applied liquid membrane that can be applied directly from the container. It contains addition of polymeric microsphers that creates a layer of insulation that minimises surface temperature of the membrane and therefore increases thermal efficiency of the building. The Product provides a seamless, smooth waterproof finish which is resistant to UV exposure and has elastic properties.

- Reduces energy for cooling of buildings
- High adhesion to concrete, render and masonry
- Low VOC content
- Resistant to permanent UV exposure
- Good resistance to mould and fungus

SUBSTRATE PREPARATION
IMPORTANT
System design
Consider the following when designing the system:
- The supporting structure must be of sufficient structural strength to support all new and existing layers of the system build-up.
- If used as a roof system, the complete system must be designed to withstand and be secured against wind uplift loadings.
- Reinforcement (partial or total) must be used over dynamic cracks and joints.
GENERAL
Substrates must be free of standing water (no puddles) clean and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
All dust, loose and friable material must be completely removed from all surfaces before application of the product, and associated system products, by industrial vacuuming equipment.
To confirm adequate surface preparation and product adhesion, carry out a trial before full application together with adhesion tests.
CEMENTITIOUS SUBSTRATES
- Substrate must be sound with a minimum tensile adhesion strength of 1.5 N/mm2, clean, dry and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
- New concrete must be cured for at least 28 days and have a tensile strength > 1.5 N/mm2.
- Cementitious substrates must be prepared mechanically using substrate preparation equipment to remove cement laitance and achieve an open textured gripping surface profile suitable for the product thickness.
- High spots can be removed by grinding.
- Weak cementitious substrates must be removed and surface defects such as blow holes and voids must be fully exposed.
- Repairs to the substrate, filling of joints, blowholes / voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials. Products must be cured before application of the waterproofing system.
BRICK AND STONE
- Mortar joints must be sound and flush pointed.
- Replace loose bricks, stone and mortar.
- Thoroughly clean the surface by power washing and allow to dry.
UNGLAZED CERAMIC TILES
- Ensure all tiles are securely fixed.
- Replace any broken, loose or missing sections.
- Thoroughly clean the surface by power washing and allow to dry.
CLAY TILES
- Ensure all tiles are securely fixed.
- Replace any broken, loose or missing sections.
- Thoroughly clean the surface by power washing and allow to dry.
MIXING
IMPORTANT
Avoid over-mixing to minimise air entrainment.
Product is supplied ready to use. Before application, mix for at least 1 minute or until the liquid is uniform.
APPLICATION
IMPORTANT
Protect from rain
After application, the product must be protected from heavy rain or rain showers until dry to prevent surface damage.
Application of successive coats
To prevent a reduction in product performance the following actions are necessary when applying successive coats.
- Ensure product is totally dry and the surface is without pinholes before applying successive coats.
- Remove surface water between coating applications.
- Confirm overcoating times have been achieved between coating applications.
No application on rising moisture
Do not apply on substrates with rising moisture.
