It's lovely material, but the install was initially pretty (conceptually) tough. Screwed up with the adhesive and had to order another piece of this. The main thing that saved the final install was using a (cordless) nailer, which made it a lot easier. If you don't have one, recommend to borrow one from a friend (hopefully you already have one). If you don't use a nailer, try to find the least obtrusive finish nails / use a precision finish tool (not sure what it is called but it's a little thing you use with a hammer to push the nail heads deeper, but not so that you dent the moulding) to submerge the nail heads. When you paint this, also recommend to start with the little domes and really work around them so paint does not pool. Finish the rest of the paint job with swipes in parallel to the length of the 'board'. I ended up using four coats of paint...it was worth it. Your mileage may vary! It's tricky material but with patience, it works. In progress photo attached.. Tamara. Granger, TX. Tue Dec 30 2025
