How To Repair Exterior Siding Gaps?

This blog post discusses various methods for filling small and large gaps in siding, including using exterior-grade adhesive and foam backing rods. For wood siding, using an exterior-grade adhesive will help the filler adhere better and provide a stronger bond. For gaps larger than 1/8″ wide, a foam backing rod can close these gaps and prevent caulking from separating over time.

There are three options for filling gaps in siding: cutting another piece of trim, filling with caulk and paint, or filling with foam and paint. The first step is to scrape off loose paint and wood, ensuring the space is clean to allow for filler and better hold. Polyfoam caulk backing can be used for wider cracks and gaps, partially filling the gap and making the sealant go further.

Using sealant, caulk, and putty knives can make your home look brand new in no time. Caulk is an incredible, flexible acrylic that can prevent air or moisture from getting in, and can be used to fill gaps or cracks in vinyl siding. If sealing is necessary, fill big gaps with backer-rods and use acrylic latex caulk. Color match caulk can be used for siding.

Filling gaps in wood baseboard trim involves using wood filler or caulk, which can be applied with a putty knife. Sealing surface gaps, cracks, holes, and other imperfections is necessary to protect and reduce the deterioration of siding.
