Using the right sealer on outdoor furniture is essential to protect it from the elements. While some furniture is made to withstand outdoor conditions, painting your own outdoor furniture requires a coat of sealer to keep the paint from fading and chipping. The type of sealer depends on the material and type of paint used, so it is important to choose the right one for your project.
1. Sealers for Wood
If you are painting wood furniture, choose a sealer designed specifically for wood.
Oil-based polyurethane is a popular choice because it provides a glossy finish that stands up to UV rays, moisture and wear. Choose a semi-gloss or gloss sheen to make sure your paint job stays looking vibrant and fresh. For less glossy finishes, try an acrylic latex sealer.
2. Sealers for Metal
If you are using metal furniture outdoors, look for an alkyd-based enamel or polyurethane formulated specifically for metal surfaces. This type of sealer will provide superior protection from corrosion and rusting due to its high gloss finish that repels water.
3. Sealers for Plastic
Plastic outdoor furniture needs a sealer that will stand up against UV rays as well as moisture and wear-and-tear.
A polyurethane sealant is ideal because it will not yellow with exposure to sunlight and will protect against scratches and scuffs. If you want a less glossy finish, use an acrylic latex sealer.
Conclusion:
At the end of the day, what kind of sealant you use on painted outdoor furniture depends on the material it’s made of and the type of paint used. For wood surfaces, oil-based polyurethanes are great choices while metal surfaces should be sealed with alkyd-based enamels or polyurethanes. For plastic surfaces, opt for either polyurethane or acrylic latex depending on if you want a glossy or matte finish respectively.
