Sealcoat PU20
SEALCOAT PU20 is a cold-applied, single-component, ready to use elastic polyurethane waterproofing and protective coating with seamless finish and excellent crack-bridging properties. Polyurethane is modified with specially selected polymers to form a flexible and durable coating. It has an excellent mechanical property that remain stable over the years making the product highly durable.

- Do not apply in temperatures lower than +5°C or higher than +40°C.
- Do not apply if it is raining or about to rain.
- Do not apply if dew is present on the surface.
- Do not apply on surfaces with residual humidity or subject to rising damp.
APPLICATION INSTRUCTIONS
- Substrate should be clean, free from dirt, dust, and all loosely adhering particles.
- Cement-based surfaces should be thoroughly saturated with water to achieve surface saturated dry condition.
- All cracks larger than 1mm should be filled with cement base concrete repair (Sea Star Crack Filler)
- Steel surface should be grit blasted then clean by solvent and kept to dry.
Sealcoat PU20 does not require priming and can directly be applied onto the concrete surfaces. In case of highly porous surface, a priming coat is recommended to seal the pores and stabilize the surfac
Sealcoat PU20 is a single component ready to use product but mix the contents thoroughly prior to application to remove any sediment. A slow speed drill and suitable paddle mixer shall be used to avoid the formation of air bubbles.
- The coating can be applied with a brush, roller or airless spray and shall be applied in a minimum of 2 coats.
- The 1st coat shall be allowed touch dry before the 2nd coat is applied.
- The 2nd coat shall be applied cross wise to the first coat.
- The coating will achieve its full strength after a curing period of 24-48 hours depending on the weather conditions.
