Finishing
All components of the TrimCraft Cornice System are wood products, and as such must receive an adequate coating of paint to enhance their beauty and extend their service life. At the time of manufacture, a factory-baked primer is applied to the product. This primer is not intended to be a finish coat.
Preparation For Finishing
Caulk wherever water can penetrate the wall assembly or accumulate behind TrimCraft. Overdriven or counter sunk nails, construction damage, and all openings should also be caulked with a paintable, mildew-resistant, acrylic latex caulk.
Primer
A solvent-thinned oil/alkyd wood primer is required for all touch-up priming where the substrate is exposed and for field-cut ends and edges.
Paint Selection
Select a paint specifically intended for exterior use on hardboard. The paint container label should list the ingredients and provide a finish-performance warranty. The label should provide specific instructions regarding method of application, spread rate, and weather condition limitations at the time of application.
Acrylic latex exterior house paint (flat, satin, or gloss) is the recommended top coat, applied according to the paint manufacturer’s label instructions. At all times the paint manufacturer’s application instructions for field priming and top coats should be followed.
The following finishes are not recommended for use on TrimCraft: semitransparent stain, shake and shingle paints or vinyl acetate (PVA) paint. Do not use flat oil/alkyd finishes.
Painting Instructions
Proper finishing includes two coats of field-applied, unthinned acrylic latex exterior paint (approximately 1.5 dry mils each) in addition to the factory-applied primer. An alternative method is to apply one coat of oil/alkyd primer and one coat of unthinned acrylic latex exterior paint (approximately 1.5 dry mils each).
Apply paint evenly with brush, pad, roller or sprayer to all exposed surfaces and edges of TrimCraft. Pay particular attention to coating the edges, ends and field cuts.
The field finishing must be completed within 90 days of installation. Failure to properly apply an adequate paint film within 90 days will void the product warranty.
