If you are looking for a general-purpose caulk that can be painted, then ALEX PLUS Latex Clear Caulk may be the product for you. However, if you need a waterproof caulk, then you might want to consider a silicone caulk. While ALEX PLUS Latex Clear Caulk may be rated as an indoor and outdoor product, there is a difference between sealing and waterproofing.
I have used ALEX PLUS Latex Clear Caulk around my home to seal the handrail on the back deck. I apply the caulk to fill cracks or imperfections in the wood, then stain with Olympic Maximum Navajo Red deck stain. My objective is to prevent water from penetrating into the wood, thus increasing the life span of the deck. Since ALEX PLUS Latex Clear Caulk can be painted, filling in any gaps prior to staining also adds value to the appearance.
While I would use this product to seal around door and window trim on the inside of a house to increase the energy efficiency, I would not use it when installing windows and doors where I wanted a waterproof seal to prevent leaking. I would not use it for sealing bathtub or shower joints either. When I need a waterproof seal, I look for a silicon product.
I purchased ALEX PLUS Latex Clear Caulk in a 10.1 oz. tube and applied with a caulking gun. The product cure time is only about 30 minutes. Unlike silicon which requires a solvent for clean up, latex caulk can be cleaned up using water and is mildew resistant. ALEX PLUS Latex Clear Caulk can be applied to most common building materials, such as drywall, plaster, wood, plastic, vinyl and metal. It cannot be sanded, so it should not be used where a wood filler would normally be required.
ALEX PLUS Clear Caulk is a DAP product.
