A Guide to Installing Primed Mouldings

If you’ve decided to purchase primed mouldings to save you time during installation, there are a few tips we would like to share to help keep your primed coating in the best condition during installation, so you can achieve a look and finish like a professional.

Cutting

• Cut from the profiled face through to the back to prevent fibre tearout that is inherent with all timber
• To ensure the best possible finish we recommend that you only use sharp, well maintained tools.

Hand nailing

• When hand nailing, the use of bullet head bright nails is recommended. The hand nailing should be finished with a nail hole punch so the nail sits just below the surface.

Gun nailing

• Ensure you adjust the gun with each moulding type to prevent the nail from shooting too deep and make sure the nail finishes just below the surface.
• We recommend you use a protective tip on the gun to eliminate any bruising that may occur on the surface.

Gluing

• When gluing back face of moulding to plaster or rendered wall, we recommend you use the following products:-
• Soudal – fix all – smx hybrid polymer or a rapid cure polyurethane based construction adhesive.

Sanding and painting

• After installation, it is strongly recommended to seal any nail holes and exposed sawn surfaces with an appropriate sealer ie. Zinsser bin, (used in accordance with manufacturer’s instructions)
• Then nail holes and small surface checkouts must be filled with appropriate wood filler then sanded.
• It is essential to wipe off dust and dirt that may have accumulated on the surface of the moulding.
• A light sand is recommended prior to applying top coats
• Further coats must not be watered down
• Water based/acrylic top coats may be directly applied and do not require another primer or sealer coat
• Oil based/enamel top coats must have a suitable primer (recommended – Dulux one step acrylic primer/undercoat or Zinsser cover stain primer sealer) applied prior to applying top coats.

Health and safety

• When working with pre-primed mouldings ensure you use all the correct personal protective equipment eg. Mask, gloves, goggles. Machine tools should be fitted with dust extractors and work areas kept clean.
• Storage and work areas should be adequately ventilated.
• Machines should be well maintained and the cutting tools should be sharp.
