Frequently Asked Questions
What is MS polymer sealant?
MS polymer sealant combines the weathering resistance of silicone with the paintability and bond strength of polyurethane. It cures by atmospheric moisture, contains no isocyanates or solvents, and adheres to most substrates without primer.
Do I need to prime before applying MS polymer sealant?
No. MS polymer sealants adhere to most building substrates without primer, including concrete, brick, aluminium, powder-coated metals, timber, PVC, and fibreglass. Check the product data sheet for exceptions on lead, copper, and some plastics.
Can MS polymer sealant be painted over?
Yes. MS polymer sealants accept acrylic, oil, and rubber-based paints once cured. Rigid coatings may crack on moving joints. The X-traseal MC-228 tile gap filler cures to a hard finish and is not designed for painting.
Will MS polymer sealant stain natural stone?
No. MS polymer sealants are formulated as non-staining on natural stone, marble, and granite. Unlike some polyurethane sealants, they do not bleed plasticisers into porous substrates. They are also non-corrosive to galvanised steel and aluminium.
What movement capability does MS polymer sealant have?
Most MS polymer sealants handle ±25% joint movement. The Hi-Flex Construction Plus reaches ±50% with 1100% elongation for large facade and window perimeter joints. The X-traseal MC-228 is a rigid tile gap filler with no movement rating.
