PAINTING • Touch up damaged areas with premium acrylic latex primer or premium alkyd oil-based primer. • Trim must be finish-painted within 90 days after installation. If trim is exposed for a longer period, reprime the trim. • Trim must be clean and dry when paint is applied. • Use only premium acrylic latex paint or premium alkyd oil-based paint containing an appropriate amount of mildewcide for local moisture conditions. • For best performance, use 100% acrylic latex paints or 100% acrylic latex solid body (opaque) stain. • Follow paint manufacturer’s recommendations for engineered wood trim. • A minimum of 4 dry mils, which includes 1 mil factory primer, is required. This is best achieved with two coats of finished paint. • All cut ends must be well coated with primer and paint or sealant. PROPER STORAGE • Store trim flat and support it on stringers to avoid sagging and contact with the ground. • Trim must be covered and protected from the elements. • Allow trim to acclimatize to local conditions prior to installation. CONSTRUCTION ESSENTIALS • The structure must be constructed to meet local applicable building requirements, HUD minimum property standards or HUD manufactured housing construction and safety standards. Trim does not provide shear strength.
• Butt joints must be located on framing members. • When a scarf joint is used, two nails are required into solid wood framing on each side of the joint (see Fig. 2). BUTT JOINTS • All butt joints must be located over studs. • Leave 3/16 in. gap at all butt joints. • Metal joint covers are recommended at all butt joints and corners. This method minimizes long- term homeowner maintenance. • In lieu of metal joint covers, seal the joint with the recommended sealant. CLEARANCES • Trim must have a minimum 2 in. separation from concrete, masonry, stucco brick, mortar and stone or be separated by appropriate metal flashing. • Trim must be 6 in. from soil or landscaping material. • Where the trim meets the roof, it must be spaced a minimum of 2 in. from the plane of the roof and be properly flashed. The cut edge must be primed and painted. • Vegetation must not be in direct contact with the trim. SEALING • Use the best quality flexible, paintable, mildew- resistant exterior grade sealant material that meets ASTM C920, Class 25 or higher. • Seal around all openings such as window and door frames and at butt joints. • Seal all overdriven nails (see Fig. 1). • Seal or flash all horizontal trim material in a manner that creates proper out-sloping.
