Installation for Polyurethane Mouldings


Step 1: Before you begin
Mark the ceiling and wall with lines indicating the edges and projection of the moulding.


Step 2: Where to start
Installation should start at the most conspicuous outside corner- moving around the room to the least conspicuous inside corner.


Step 3: Mitering
We recommend that all inside and outside corners be MITERED. Miter cuts should be done in the miter box with mouldings places as if mounted on the wall. The miter cuts should be made with the moulding bottom side up.


Step 4: Matching Patterns
It is very important to check the thickness of each piece of moulding. Variations may occur from piece to piece. If an adjustment is needed, reduce the thicker part by using a planer or a piece of sandpaper on the back of the moulding. Match pattern and thickness together before final installation.


Step 5: Adhesive
Using adhesive is necessary for correct installation. Spread adhesive evenly over the surface area that will be bonded to the wall and ceiling and on the cut ends where moulding will be joined together. Make sure mouldings are clean and dry before apllying.


Step 6: Installtion
Bring moulding ends together for a tight fit in order to avoid joint separation. Mouldings should be cut long, thereby assuring the tight fit required. Using finishing nails, nail into studs to secure mouldings to walls and ceilings. Counter-sink all nails to secure. Be sure to use adhesive on all joints to ensure a great installation.


Step 7: Final Touches
Remove all excess adhesive material. Fill nail holes with wood filler.


Step 8: Painting and Sanding
Chemcrest moulding comes with its own primer coat already applied. The mouldings are ready for any good quality oil-based or latex paint.
Moulings with a grained surface can be stained. Just make sure the surface is free of any dust or grease, then using a gel or solid stain apply a heavy coat making sure to cover the surface completely. Let dry for a short time and wipe or dry brush off excess until the desired shade is obtained. If a toning effect is desired, wipe some areas more thoroughly than others and use a dry brush to blend the colour. After the stain dries it is imperative to apply a protective coat of varnish or urethane sealer.
