Which silicone sealant is best to buy?

The best silicone product to buy will all depend on what material that needs sealing. If you’re working with wood and need to fill holes or chips, then wood sealer will be best. If you’re needing seal in a bath or basin once you’ve finished painting then using a waterproof sealant like bath silicone would be ideal. These questions will help you decide which product is best to buy and what kinds of quantities to get too:

  1. What product or material type do you need to seal?
  2. Is the material indoors or outdoors?
  3. What is the size of the area that needs sealing?

Once you know this, then deciding which silicone sealer to use is easier. At BUCO we offer the best silicone sealant price on the market, so be sure to shop at BUCO online or in-store first for the most competitive prices around. When prepping to paint, be sure to check out these additional products in our Paint Prep Department;
