Polyurethane is another popular caulking material known for its weatherproof and sealing properties. It is typically used as an exterior caulk and can be easily applied with the use of a caulk gun. Unlike silicone caulking, it can be trimmed and painted over and it creates a strong seal that remains intact when exposed to temperature changes and other weather elements. Another type of polyurethane sealant, polyurethane foam, is commonly used for installations of windows and doors.
It is applied to fill rough openings and expands to bond wood, aluminum, and other materials, and seal big gaps without causing frames to bend. The water-based formula of acrylic caulk has many benefits. Although acrylic latex caulks are not considered a durable exterior caulk, this caulk is still a great choice for interior applications as it contains fewer hazardous chemicals than other types of caulking and does not have a strong odor. Acrylic caulk can be painted to match any finish.
Once applied, any excess caulking can be easily cleaned with water. Butyl rubber caulk and other specialty caulks are commonly used around the house exterior but are formulated for other applications such as sealing gutters, roofs, siding, and other areas exposed to the weather.
While they withstand extreme temperatures and protect from water damage, these types of caulks are not as flexible and therefore are not preferred for window applications. Before applying caulking, it is important to ensure that the exterior or interior area is free of wet surfaces, frost, dirt, and dust in order to achieve a strong bonding and clean and long-lasting results.
Each caulk has different properties when it comes to the temperature range at which it can be applied, its curing time, and other important details. Any caulk that comes in a cartridge requires the use of a caulk gun. While most cartridges will be compatible with any regular caulking gun, some professional-grade sealants require the use of specific guns of the same brand. Caulking guns have trigger handles that apply pressure to force the caulk out of the cartridge nozzle. When caulking an old window, aside from making sure that all surfaces are clean and dry, you will also need to remove any old caulk.
This can be done with the help of a putty knife or scraper. Some silicone caulks can be smoothed into the joints using your finger and are water-ready within an hour. Polyurethane caulks can be easily cut to frame after drying.
