Excellent Crack Sealing thanks to Protectosil® Degadeck® CSS

NEW CRACK SEALER extends the lifetime of concrete constructions

Protectosil® Degadeck® CSS is a two-component, low viscosity methylmethacrylate (MMA) resin for use on horizontal concrete surfaces. Protectosil® Degadeck CSS is formulated to have excellent penetration into the crack while maintaining high compressive and flexural strengths. In addition, the product cures quickly to minimize the time in which the traffic lanes or parking decks need to be shut down for repairs.


Crack sealer, damaged stone
Excellent crack penetration - cures within two hours

When the liquid resin (Protectosil® Degadeck® CSS) is combined with the hardening powder (Protectosil® CSS BPO), a rapid polymerization occurs allowing the product to quickly harden and thus, be opened to vehicular and pedestrian traffic within two hours of application. The low viscosity and low surface tension of Protectosil® Degadeck® CSS provides excellent penetration into the concrete, sealing cracks ranging in size from hairline up to 1/8" (3mm). 

Extended service life of concrete structures

Fully cured, Protectosil®, Degadeck® CSS creates a barrier which prevents the ingress of water and chloride ions from entering the substrate and causing premature deterioration. Excellent adhesion and strength characteristics ensure for long lasting performance, extending the service life of concrete structures.
