Seal Wood Expansion Joints and Cracks

now I'm putting one coat over the wood and the cracks I'm going to go back but be using a product from Tower sealants a u au1 sealant I'm going to go back over after my first coat I'm going to seal these wood joints and some of these cracks that have opened up again I'm going to go over those with the au1 this is sealant so I'm just going to brush that coat initially over this wood that'll seal it prime it and then I'll go back over it with my joint sealant some people might ask how many coats do you typically apply if this has never been stained before I'm going to apply two coats of stain and I'll be finished this has already been coated this is three years ago it was coated so just one coat or the same color if you're doing a color change you're probably going to have to do two coats I like sealing the joints and cracks too to keep bugs keep dirt moisture out to keep it from continuing to crack so I'm just cutting in right
