2.3 Do not allow a seam in the Rough Top material to fall within a cabinet that is wider than 18”. The plywood needs to be supported at its ends by vertical cabinet sides or panels in order to withstand a lifetime of use. It is OK to place a seam within a cabinet that is 18” wide or smaller, as long as the seam is reinforced with a plywood gusset using glue and 1-1/4” screws. 2.4 Confi rm all Rough Top is fastened completely and all of the attachment screws are at least fl ush with the top of the material. Ensure that no splinters in the plywood ex- tend more than 1/16” above the surface. 2.5 If you have a large piece of Rough Top to cut for an island, it can be helpful to fasten it in place fi rst and then cut it to size. Field Tips: It is possible that Rough Top could get wet at some point during the life of the kitchen, especially in the spans over the dishwasher and around the sink. Water or even humidity can make plywood swell and buckle, which can lead to failure of the countertop material. For this reason it is important that the Rough Top is secured properly with screws and that the seams are well laid out, supported and reinforced as needed. ©2017 PCS Professional Cabinet Solutions.
