You need no special tools on the jobsite to work with Plycem! Use a circular saw blade with carbide-tipped teeth to cut the trim. You should avoid generating dust by using tools equipped with a dust collector, and never use water while cutting. Always wear safety goggles and dust protection equipment when operating cutting tools.
Use a corrosion resistant or stainless steel nail with a minimum 0.113 inch gauge and minimum 9/32 inch head. Nails must penetrate at least 1 inch into solid wood. To install Plycem Trim to steel stud constructions, use a corrosion resistant or stainless steel screw. Repair any dents, cracks, and over-driven nails by filling with a cementitious patching. Of course, Plycem is not responsible for the corrosion resistance of fasteners. Do not use staples when installing.
Position fasteners no closer than 1 inch from the side edges of the trim and no closer than 3 inches from the end. Space fasteners a maximum of 24 inches on center. For trim with a 3.5 inch width or less, fastening should be applied in an alternate position to both sides of the piece. For trim with a 5.5 inch width or more, apply two fasteners, one on each side of the piece, spaced no more than 24 inches apart.
Fasteners should be driven perpendicular to the board surface and must be long enough to penetrate the framing at least 1 inch. Always begin nailing at one end and proceed to the other to avoid stress on the board. Never nail both ends to the middle. Fasteners should be driven flush. Do not nail the face board into the edge of another.
Plycem is easy to paint and it is factory coated on six sides with a high quality primer and water sealer mixture which provides an excellent base for painting. Plycem Trim products MUST be painted. Always use paint and coatings that are permeable to water vapor. 100% acrylic latex paint is highly recommended. To ensure maximum product performance, apply a 100% latex primer and paint to all field cut areas. Follow the application recommendations provided by the paint manufacturer.
Leave a minimum gap of 1/8 inch at trim for caulk. Use caulks that comply with either ASTM C 834 or ASTM C 920. Apply caulking in accordance with the written instructions from the caulking manufacturer. Use a high performance, paintable low-modulus elastomeric sealant.
Allow a minimum 3/4 inch clearance between the roofing and bottom edges of trim. Flashing and counter flashing should be installed at the intersection of the roof and vertical surfaces as recommended by the roofing manufacturer.
No. Plycem is factory primed on six sides with a high quality primer and water sealer mixture to provide an excellent base for painting. To ensure maximum product performance, apply a 100% latex primer and paint to all field cut areas.
Store Plycem in a weather-protected area. Keep it flat and off the ground on stringers or platforms. If a covered area is not available, place skids on wood blocking to allow air flow underneath. Shelter Plycem with a waterproof covering.
