We have either plywood or particle board type wall paneling with grooves to stimulate pood panels. Thes are not a suitable backgroung for the wall hangings we hang in the living room. We wand a relatively smooth white background with no grooves apparent. I looked at some earlier threads where it was advised to fill cracks and tape the seams between panels as with drywall and then paint but that would be too much work as I have trouble getting a perfectly smooth surface. I am thinking taping the joints and filling in the grooves with mud as in drywall then using something liked textured paint and a roller. What problems might I have with this and what would be the best method?
P.S. I saw the earlier thread where a fiberboard wall warped when covered by wall paper but I think our wall covering can accept the moister without warping
