When compared to industry standards and previous silicone sealants, Everbuild SIKASIL 825PORT stands out thanks to its tailored compatibility with Portland Stone and enhanced movement capability. Traditional sealants often lose elasticity or show early signs of discolouration, particularly when used in heritage and masonry projects. In contrast, SIKASIL 825PORT delivers long-lasting performance without compromising appearance, thanks to its steadfast colour-match and advanced weatherproofing qualities.

Key Technical Advantages:

• Exceptional adhesion to concrete, natural stone, and masonry surfaces minimises joint failure risks.
• Low modulus formula absorbs building movement, preventing cracks and maintaining a seamless finish even in challenging British weather conditions.
• Its neutral cure technology prevents staining and corrosive reactions, which are common in acidic or alkaline environments.
• Easy to apply with a standard sealant gun, the 380ml cartridge ensures minimal wastage and consistent bead application for professional results.
• UV and temperature resistance extends the lifetime of your building’s joints, reducing future maintenance costs and preserving the aesthetic of Portland Stone façades.
