From bathroom to window repairs and more, find different types of caulk fit for your specific project at Ace, and get the tools you need to get the job done right.
What is Caulk Used For?
Caulk, or caulking, is a material used to seal joints or gaps around windows and doors to protect against energy loss, moisture, dust and insects.
But window caulk is just one type of caulking. It’s also used for a host of other applications:
- Bathroom caulk is used to seal plumbing fixtures and pipes to prevent leaks.
- Concrete caulk is used to repair masonry to help prevent erosion.
- Fire caulk is rated to withstand high temps and expand in fires to help ensure fire safety.
Read on to learn more about which type of caulking you need for your specific job.
How to Choose the Right Caulk or Sealant
Different types of caulk are used for different types of projects:
- Acrylic latex caulk: This general-purpose, indoor caulk can be painted and cleaned with soap and water. It’s best for sealing baseboards and wood molding.
- Latex with silicone: This door and window caulk is the same as the basic acrylic latex, but it has silicone added for better waterproofing. Latex caulk with silicone can be used to seal around doors and windows, both indoors and outdoors.
- Pure silicone caulk: This premium sealant is ideal for high-moisture situations like tubs and showers. Clean-up for bathroom caulk jobs requires mineral spirits.
- Butyl rubber caulk: An outdoor caulk used to seal rain gutters and roofs, butyl rubber caulk also requires mineral spirits for clean-up.
- Refractory, or fire caulk: This fire-resistant caulk is used to seal fireplaces and other high-temperature materials.
- Masonry repair caulk: This highly flexible concrete caulk is used to seal seams and repair damage in bricks, stucco and concrete.
Caulking Guns
Caulk comes in squeeze tubes or cardboard or plastic cartridges that require a caulking gun, which is typically made of metal and has a trigger connected to a rod that pushes a plunger into the cartridge, forcing the caulk out.
Tips for Applying Caulk
Different caulking jobs require different caulking tools and materials. If you need to remove old caulk, putty knives, razor blades and caulk remover tools are essential.
To apply new caulk:
- Thoroughly clean the area to ensure the caulk will properly adhere. Use mild soap and water, then rinse and ensure area is dry before you proceed.
- Cut the tip of the tube or cartridge at a 45-degree angle to the appropriate size for the job. Larger cracks and gaps will require a larger opening than smaller cracks and gaps.
- Hold the tip of the tube or cartridge at a 45-degree angle against the joint, starting at one end. Slowly squeeze the tube or trigger, and, as the caulk comes out, move the applicator along the seam or crack at a consistent speed for a smooth application.
- To smooth the bead of caulk and remove any excess, lightly draw your finger or a caulk-smoothing tool along the bead.
- Allow the caulk to cure according to directions before you let it get wet.
