What is Silicone Caulking? 

Think of it as a gel-like material that helps seal gaps in various parts of the house. It is applied by using a caulking gain. The one I will refer to on this article is what we use more here in Canada because of our climate- silicone based caulking (local tradesman refer to this as DAP). This sealant keeps away water and debris and can be used on the exterior or interior of your home and can help your finish look more aesthetically pleasing.

Interior use may include:

Outside use may include:

So… How to remove Silicone Caulking?

1. Try to weaken/soften the caulk with a Caulk Remover– I recommend this one by Goo Gone. Simply spray lightly onto the caulked surface. I recommend letting the material sit on the caulking between 3-4 hours as it just loosens the material with time. 

2. Once the caulk remover has had time to settle onto the surface use a putty/utility knife to slice through the caulk. I would recommend slicing at it diagonally to avoid any damage to the surface. You should be able to get a good amount of the caulk out with this method.

3. There will always be a bit of residue left but you can use even a small toothbrush or straight edge to take out the rest. Another way I have seen contractors remove stubborn caulking is by applying a hair dryer AT THE LOWEST SETTING. 

4. Please make sure you remove the mineral residue! If you dampen a sponge with mineral spirits it should be able to remove any residue with ease. As always please make sure you handle the sponge with gloves as it can irritate your skin

5. For the fifth step, PLEASE MAKE SURE you don’t just figure out how to remove silicone caulking. PLEASE use a caulking gun to re-caulk before using the area. You do not want to leave the caulking exposed as I have seen bad situations where water has crept into the crevice and caused mold/rotting on studs/drywall- resulting in an expensive repair!
