Intergrain UltraPrep Timber Cleaner (previously known as Reviva) is a high strength cleaner that contains oxalic acid and citric acid, both naturally occurring, bio-degradable organic acids. Use UltraPrep Timber Cleaner to clean all timber prior to coating. UltraPrep Timber Cleaner will help restore and prepare weathered, grey, rust or tannin stained, mold or mildew affected timber to a clean appearance ready for coating.

Available in 1L & 4L.

Application:

Shake Intergrain UltraPrep Timber Cleaner thoroughly. Mix one part Intergrain UltraPrep Timber Cleaner to four parts water in a plastic container. For severely stained surfaces a stronger solution or repeat applications may be necessary. Tannin rich timbers may also require repeat applications; wash until the water used to rinse off is clear.

Wet the timber surfaces to be cleaned with water.

Apply Intergrain UltraPrep Timber Cleaner mixture generously to the timber with a stiff bristle brush. Scrub the timber vigorously. Spot cleaning should be avoided to prevent patchy results.

Leave mixture on the timber for 10-15 minutes. If necessary, apply more mixture to keep timber damp throughout this period, do not allow mixture to dry.

Rinse off surface thoroughly using maximum pressure from a garden hose or using a high pressure water cleaner (recommended for large areas or badly discoloured timber). Failure to thoroughly rinse off the mixture may result in timber discolouration under clear finishes.

Note: After cleaning, some timber species will appear lighter due to loss of water soluble extractives. Richer colour is generally restored on application of the finish.

Available in 1L and 4L containers Mix 1 part Cleaner to 4 parts water Coverage: 1L of concentrate covers approx 10sqm (e.g. 1L Cleaner + 4L water covers approx 10sqm)
