Hello, I am about to install some waincoting and I would like to minimize the future gaps in the miter joints.
I have purchased the longest boards I can but I will still have joints. My top and bottom rails are 1x6 and primed white from the lumber yard. Is there a product I can apply to the wood (even if its primed white already) or can I apply a product to my cuts ?
I have installed 1/4 inch MDF on the wall, I plan to build boxes from 1x6 (rails) and 1x4 (stiles) trim it and paint it. The 1/4 MDF is mostly so I do not have to be concerned with studs - mostly to make the job easier for me as a homeowner.
When I install the rail, do I use my plate joiner and a biscut or do I miter the joint? the wall is 23 feet and I think my wood is 18 feet, so both rails will require two peices.
