Rated 5 out of 5 by Alma from Great Quality We love getting the boards from Grimco; They print great on our UV flatbed. In the past, a few boards arrived warped, which we believe was due to delivery handling—but recently they’ve been arriving very flat and in great condition.

Rated 4 out of 5 by Connie V from Good boards with a little work the board are nice and smooth, but not flat and the edges have to be repainted or caulked so water doesn't get in.

Rated 2 out of 5 by Tony Karam from Flaws and Lack of Grimco should have more details on their website that the back side is not primed which means it is not waterproof (according to one Grimco employee whom I contacted to ask). I had to return the item and pay a fee. Imperfections in the manufacturing. I bought a total of 6 sheets and they all had more than one 1"-circle lump on both sides. One sheet had a 36"-long lump. I had to scrape those areas and prime and paint in order to get them ready for vinyl mounting. On the positive side, the acrylic paint is great and I would have given the product five stars if it did not have all the flaws.
