Part 3 of the caulking 101 series.
You’ve done the work, installed that new bathroom vanity and countertop. You’ve got the plumbing hooked up and tried out the faucet, yep, everything works. All that’s left is to seal the countertop to the wall, that finishing touch that completes the installation. Is that bead of sealant simply cosmetic or is it to prevent water from flowing behind the countertop and vanity possibly causing damage? Do you use a cheap caulk from the hardware store? Maybe some silicone? Which product is right for this job?
Probably the most difficult decision for any caulking job is knowing what to use when and where. With so many choices, walking down the caulking aisle in any hardware store can make your head spin. With this post, we are going to talk about the chemistry of sealants, just the basics, enough information so you can make an informed decision the next time you need to choose a sealant.
