Put on PPE gear to protect yourself when using sealant

Before you get any sealer out, you need to make sure you are protecting yourself from the possible effects of the sealant. Sealants of any kind are typically dangerous to inhale and can irritate the skin if contact occurs. Make sure you have the correct PPE gear to protect yourself when sealing a brick kitchen backsplash. You should have a respirator mask and keep a window open. This allows the sealant fumes to escape the house and not be inhaled. Inhaling sealant fumes can cause damage to the internal organs, similar to the effects of inhaling dust.

You should also do your best to cover your skin as much as you can. Sealants can cause damage to your skin, including irritation to the eyes, nose and throat. Wear coveralls if you can, but you should definitely wear gloves.

Finally, you should wear goggles to protect your eyes.

Depending on the sealant you are using, you may need to keep the surface wet throughout the process. You can dip a sponge in the sealant and continuously wipe the wall with that to do so. Read the instructions of the sealant you’re using to be sure of exactly how to keep the surface prepped while applying it.

You’ll need to be somewhat quick here to prevent it from hardening too much. Rub in a circular motion until the bricks are dry and smooth.

Keep buffing until the wall is smooth and the sealant doesn’t feel tacky. If you follow all these steps, your brick kitchen backsplash will be thoroughly sealed!
