GK Render Cleaner 5LTR

This is dependent on the biological loading of moulds and algae. (How much biological growth and staining is on the surface)

For mild staining, you should see results in a couple of days, although heavier loads can take 2-3 months to see viable improvements, and in severe cases of contamination, it may take 6-12 months to work or to see the full results.

The reason for this, is part of the removal process is dependent on the weather cycles to remove dirt and biological contaminants from the surface. Once Render Cleaner has killed any biological growth it takes time for these to be weathered off the surface by mother nature.

The effects of subsequent applications or maintenance cycles will be seen quicker and usually within days.

It can be applied all year round, however results may be affected if rain occurs within 24 hrs and if temperatures are below 8 degrees Celsius.

Render Cleaner should be applied to a dry surface, and before applying any excess debris and bulky vegetative growth should be removed. Ideally it should be applied on a dry day with little or no wind. Whilst warmer weather will improve results applying on slightly cooler days with minimal evaporation, will allow the surface to remain wet for longer, giving the product time to work.

Once dry Render Cleaner is safe around children and animals, however good practice is to keep them away during application.

If you need access to an area before it has dried, you can rinse it down with fresh water after an hour or more, although this can reduce the effectiveness, and it is best to let the product dry naturally.

Render Cleaner is plants safe provided you do not spray them directly. If you accidently overspray onto them, rinse down with clear water from a hose. It may scorch foliage, but it should not kill plants and grass lawns recover very quickly. It is good practice to protect them with waterproof fabric covers or plastic prior to spray.

It can also be used to clean painted surfaces without the risk of damaging the paint film.

Can be used on decking, shed, fences, window frames and wooden garden furniture, it will prevent wood rot and disinfect as well.

Yes. Once clean and dry you can paint over treated surfaces.

However, depending on contamination, you may want to leave the dead bacterial growth to start decomposing for 2-3 weeks prior to painting (or staining). You can then wash the surface and the dirt and residue will be easily removed.

As a natural surfactant Render Cleaner will help remove dirt & grime that causes fading as well as keeping surfaces free of moss, mould, and algae. If used annually it can help extend the maintenance or painting cycle.
