Surface and Timber Species Preparation

It is essential that all exterior timbers are correctly prepared  prior to coating with ultra V Timberguard Primer & Finish. Correct pre preparation will ensure that your deck or timber feature, once coated with Timberguard Primer & Finish, will look & perform to all expectations. Surface Preparation NEW & OLD Timber

Protect any walls, windows and garden plants by using plastic masking sheets and plastic drop sheets.
All timber surfaces NEW & OLD should be washed with Timber Prep deck wash (oxalic acid) mixed with water to remove natural resin, wax or tannins. Clean the substrate with a low pressure power washer (1000—1200 psi) or a standard garden pressure hose, ensure that the deck wash is completely removed. Take care not to raise the fibres. If this happens a light sanding will be required prior to coating.
Oily resinous timber such as Spotted Gum, Tallow wood and Teak should be left for 8/12 weeks to weather and then thoroughly wash with Timber Prep and apply using a stronger mix of 1:2 parts water. This process may have to be repeated prior to coating if the resin continues to leach out of the timber.
go site Timber decks previously coated with an Acrylic stain coating should be sanded back to the original substrate using 40 – 60 – 80 grit sand paper and then finished with 100 grit sand paper and finally washed with Timber prep (oxalic acid) to clean the timber.
For previously coated decks coated with Timberguard ensure there is a sound coating, and wash with a detergent/degreaser. If there is any de lamination of surface present you may have to sand the damaged section to get back to a sound substrate prior to re coating using 100 / 120 grit sand paper.

Wash the deck with a degreaser detergent first and ensure that all the oil is out of the surface. This process may have to be repeated several times. Then apply Timber Prep deck wash (oxalic acid) to remove any dust and oils.

Dressed timber should be washed with follow link sodium per carbonate mixed with water (Nappisan™) and then cleaning with Timber Prep (oxalic acid) using a stiff brush and garden hose or pressure washer, being careful not to raise the timber fibres called fuzzies. Rough sawn timber should be washed the same as dressed timber finishing with Timber Prep (oxalic acid) and using a stiff brush or pressure cleaner to remove grey or black timber fibres. Ensure that the acid is completely washed off. Protect all plants and non coating areas with plastic sheets. Do not sand this type of timber finish.

Treated Radiata Pine

Refer to the web site for Surface & Timber Species with regards to the various types of treated pine and how to coat with Timberguard. LOSP treated pine should not be coated with Timberguard.

Minimize Tannin Leaching

By fully enveloping the timber with Timberguard, including the ends, you will drastically reduce the problem of leaching, particularly in timbers such as Merbau, Jarrah, Tallowood and other hardwoods.

Mould, Mildew, Algae & Fungus

These growths generally cause a black, green or grey discolouration on the timber.

If mould, mildew, algae or fungus is present in the timber, treat with household bleach mixed with detergent and water. Start out using 1 part bleach to 3 parts water, or add 25% bleach to your detergent mixture. It is important to protect plants and other surfaces prior to the use of any bleach. Do a test on a spare piece of timber first to ensure there is no reaction or discolouration to the timber. Apply the mixture to a wetted timber and use a stiff brush to remove any mould or mildew. Do not let the timber dry out before removal, to re activate the solution wet with cold water or apply more solution. Ensure complete removal of the solution with cold water and allow 24 hours for the timber to dry before application of Timberguard Primer no 2 and Timberguard Natural Tone no3.

Removing Fuzzies

Fuzzies can become a problem at anytime, especially with unprotected timber. The sun UV rays kill the outer layer of wood and this is what turns a deck grey. When washing is done this outer layer of dead wood is what is removed. Sometimes this results in the furring of the wood called fuzzies, in particular with wood that has not had any protective coating for long periods. It’s as if the wood has grown a lot of short hairs. It is caused by the tearing of the wood fibres. If left alone they will generally disappear in about 2 to 3 weeks.

This can be easily removed by light sanding with 80 / 100 grit paper or using a good stiff deck brush.

Roller / Flat lambs wool applicator / Brush
Mask up all vertical wall edging that is not to be coated so that the roller / flat applicator can be run hard up against the wall. Lay down any drop sheets required. Before starting ensure that you have all brushes, applicators, trays, damp rags and drop sheets ready for use.
It is very important that the Timberguard is not applied to a hot timber surface. Make sure that there is not any rain due within 24 hours of the coating and that the timber surface is free of dirt and is dry.
Spray Gun
As with rolling, mask up all vertical wall edging and windows with sufficient plastic cover mask sheeting to protect from any overspray. If coating wall cladding then ensure that the roof line is protected with plastic cover mask sheeting as the spray can blow back in corners etc.
If using an air assisted spray gun ensure that there is no wind to blow the excess product away from the spray area.
If you are using an airless spray gun set the pressure low to about 1200 PSI to ensure that there is not an excess of product applied that can cause product runs. You should always test prior to application by spraying on a piece of cardboard.

Product Mixing / Pot Life

Timberguard Primer STEP 2

Before the Timberguard Finish Natural Tone is applied to the exterior timber surface it is very important that the Timberguard Primer (Step 2) is applied to penetrate and moisture proof the timber. This will ensure the best possible protection for the Timberguard Finish.

Packaging size : 4 Litre & 10 Litre drums

Timberguard Finish STEP 3

Apply the Timberguard Finish (step 3) Natural Tone to the timber surface after the primer has been applied to achieve maximum protection.

Once the amount of product has been poured into the applicator tray, bucket or spray gun pot ensure that the lid is replaced on the container of the Timberguard polyurethane. This is a moisture curing product and will begin to react with the atmosphere.
***Remember that the first coat will absorb into the substrate and therefore will require more product. This will especially apply to coating rough sawn timber.
