About Null
EQUISOL NULL
Kills mould, algae, moss and lichen.
Advanced formula penetrates to deep rooted spores on many surface types.
Purpose-made to kill bacteria, mould, algae, moss and lichen. Low toxicity, biodegradable and environmentally responsible. When using on timber, follow up with Equisol Prime and Equisol Vitalise to fully prepare for oiling.
WHERE TO USE:
Equisol Null is suitable for surfaces including timber, concrete, steel, roof tiles, fibre cement and internal walls. Surfaces coated in paint or poly-urethane film coatings need to be stripped and sanded first.
CLEAN UP: Water
SIZES AVAILABLE: 1L, 4L, 20L
COVERAGE: Approximately 20m2 when mixed with water
PREPARATION
Sweep surface and wash down with water. Mask areas not to be cleaned, as Null may damage other coatings.
APPLICATION
Wear protective gloves and goggles. Mix ONE part Equisol Null with FOUR parts water in a clean plastic container and stir thoroughly.
Apply mixture to entire surface (not just area with visible growth) with stiff bristle brush and scrub lightly. Leave on for 24 hours to reach deep spores. Keep surface moist as long as possible with repeated light mists of water to keep formula mobile.
Rinse off thoroughly with a high pressure water cleaner to remove the dead mould build up and spores. Soak surrounding vegetation to minimise damage to plants.
When using on timber, follow up with Equisol Prime and Equisol Vitalise before oiling.
For heavy mould growth on timber, or in mould-prone areas, re-apply Equisol Null at double the recommended dilution (ONE part Equisol Null with EIGHT parts water) after using Prime and Vitalise. Leave on as a sterilisation agent to minimise future mould spore growth. Allow to dry. Do not wash off. Oil timber with Equisol.
