• WashingusingReseneTimberandDeckWashwill condition the timber allowing the stainto penetratemore easily and deeply into thetimberaswellasremovinganyfingerprints,dirtandrainspotting.

• Any surface imperfections should be sandedand sharp edges arrised or rounded.Thiswillensure better coverage. Remember to sandwith the grain. (Recommend 120-150 gritgarnetpaper).

• Recommend that both sides of the timberor board and any cut ends are coated beforefixing. This is known as envelope sealingand improves the dimensional stability of thetimber, reducing the likelihood of the timbercupping,warpingandsplitting.

• Some timbers, have hard exposed ‘latewood’grainand stainshave troublepenetrating theexposedsurface. Anothercoatmaybeusefulafter say three to six months. Depending onthecolour,stainsmayneedmaintenanceaftertwo summers but thereafter have improvedlife because of material build-up.

Wash with Resene Timber and Deck Wash to remove any dirt and contaminants. Rinse thoroughly and allow to dry.

Recommend Resene Waterborne Woodsman is applied to both sides

of the timber or board BEFORE fixing (envelope sealing).

Sand if practical to remove any sharp edges and any greyed (U.V. damaged) areas.

Apply second coat of Resene Waterborne Woodsman after fixing. Consider a third

coat for difficult to access areas for increased durability.

Alternatively recommend solventborne Resene Woodsman is applied to both

sides BEFORE fixing (envelope sealing).
