I'm relatively new to the woodworking world, mainly building simple furniture for myself and close friends. But I am always looking to learn and get better, so I thought I would join the forum. Finishing has proven to be my biggest struggle.
I decided to build a set of Adirondack chairs for my backyard. I stained the chairs they desired color and slapped a coat of polyacrylic on it without thinking. I have since read that polyacrylic will not be good in outdoor applications. It will turn cloudy and lose adhesion. Can I lightly sand this coat of poly acrylic, and put a clear water sealant over it? Is there a clear outdoor water sealant with a matte finish?
Luckily, I only put polycrylic on one chair before I thought better of it. What would your recommendation (product) be for the others at this point? And should I go ahead and scuff up the polycrylic and use this product over it on the one chair?
ANY film finish, including spar varnish will fail (fairly quickly) if exposed to outdoor environment. Penetrating oil finishes will last longer but will require regular maintenance but at least they don't fail by peeling off the surface like varnishes.
Paint is one of the most durable finishes and protects the wood. And you can use any colors you like…
