Frequently Asked Questions

What is the best silicone for around the sink?

The best silicone for around sinks is a waterproof, mold and mildew-resistant caulk. It should be water-based and specifically designed for use in kitchens and bathrooms. Before applying it, make sure to clean the area well with a damp cloth and apply a primer if necessary.

Which sealant is best for the kitchen?

When deciding which sealant to use for a kitchen, there are a few factors you should consider such as the material used, the area being sealed, and the types of food and liquids that will be in contact with it.
For example, if you are sealing metal surfaces to prevent corrosion, an acrylic or epoxy sealant would work best.
For countertops and backsplashes made of granite or marble, a silicone sealant would be ideal as it is highly resistant to water and temperature changes.
It is important to choose a sealant that is specifically designed for kitchen use as some products can be hazardous if they come in contact with food or drink. Additionally, make sure the sealant you select is non-toxic and does not contain any volatile organic compounds (VOCs).
