15 Tips For Perfect Sealant Results Every Time
The selection in the caulk aisle at home centres is mind-boggling, but actually choosing the right one is pretty simple. Most of the caulk on store shelves is basically one of four types: elastomeric, polyurethane, latex or silicone. Here’s how to make the right choice:
Siding, windows and doors: Polyurethane is best. It’s paintable. It doesn’t shrink. It stays flexible. It adheres better than silicone, and it doesn’t attract dust and dirt the way silicone does.
- Roofing: Use an elastomeric or rubberized product. This stuff won’t dry out in extreme conditions, and it sticks to everything.
- Interior trim: Use latex if you’re sealing gaps and nail holes in trim that’s going to be painted. It cleans up easily and dries fast. It’s also easy to tool—and cheap.
- Kitchen and bath: This is where silicone products shine. Silicone tools well. It can be purchased with antimicrobial additives, and can be easily removed and replaced when it gets grungy.
