Preparation: Restoring a grey weathered deck



When timber is left to age with no coating to protect it, it can appear grey. The grey appearance represents degraded timber fibres, before coating, your timber must be cleaned properly to remove the dead fibres.

What happens if you don’t use a timber cleaner before coating?

Because the grey timber is weather damaged, it is dry and absorbent. If you attempt to coat grey timber, most of the coating is absorbed and can cause the finish to be dark and muddy. Grey timber fibres are also not a sound surface which can compromise the adhesion of your coating.

Cleaning with Intergrain® UltraPrep Timber Cleaner will restore the timber to a sound surface and will brighten the colour of the wood. Proper preparation will ensure you get the best finish out of your chosen coating.



 

Steps to remove grey timber fibres and ready the surface for coating:

Sweep the surface to remove dirt and hose down with water.

STEP 1:

Mix 1 part UltraPrep Timber Cleaner to 4 parts water in a bucket.

STEP 2:

Apply the mixture to weathered timber with a stiff bristle brush.

STEP 3:

Leave for 15 minutes. Do not allow the timber to dry, keep applying product to keep the timber wet if needed.

Step 4:

Wash off using a high pressure hose.

Remove excess water and allow the timber to dry for at least 1 hour before coating with your product of choice. For help choosing the best product for you, check out our article on Choosing between an oil and a stain.

CAUTION: Wear waterproof gloves and safety glasses. Avoid contact with painted, glass, concrete or metal surfaces and vegetation. Protect areas not to be cleaned. May be corrosive to metals. Rinse off thoroughly if contact occurs.

The process is simple and just by cleaning and applying two coats of UltraDeck Timber Oil you can bring a tired looking deck back to life.
