Frequently Asked Questions
Can I paint over silicone sealant?
No. Silicone sealants do not accept paint on any surface. The cured surface remains inert and repels coatings. If the joint needs a painted finish, use an MS polymer or polyurethane sealant.
What movement capability do silicone sealants offer?
Most silicone sealants handle ±25% joint movement. High-movement products reach ±50% for facade and cladding joints. The Dowsil 890-SL pavement sealant handles +100%/−50% for large expansion joints in concrete slabs.
Is silicone sealant safe to use on glass and mirrors?
Yes. Neutral-cure silicone is the standard sealant for glass, mirrors, and glazing joints. It does not release acetic acid, so it will not etch glass or corrode metal frames. All products in this category use neutral-cure chemistry.
Does silicone sealant stain natural stone?
Most silicone sealants can bleed oils into porous stone and cause staining. The Dowsil 795 is a neutral-cure product tested as non-staining on marble, granite, and limestone. Check the product data sheet before applying to stone.
What is the difference between gloss and matte silicone sealant?
Gloss silicone has a shiny finish suited to glass and polished surfaces. Matte silicone (such as the Adheseal Matt Seal S-250 and S-350) has a flat finish that blends with tiled surfaces and painted walls in wet areas.
Can I use silicone sealant in a swimming pool?
No. Silicone sealants are not rated for permanent water immersion or chlorinated pool environments. For underwater or pool applications, choose a purpose-made pool sealant or an epoxy system rated for continuous submersion.
