Sika Mould Buster 5Lt

Fantastic stuff for brightening paving and lockblock. Works slowly over a couple of weeks, so don't be impatient

this really works and saves you power washing and breaking surface of your stone. Really do recommend

This worked well in removing mould and fungi from the external walls of our house. It needed a couple of applications in some places, but a good product.

Always use this , great for keeping flags clean and even when they get a bit of mould on over the winter they come clean really easily.

I was given a small amount of Moldbuster by a friend who said it was amazing. I sprayed an area to see. Nothing happened for months then it started to work. The picture shows the area I treated. I am totally amazed how well it has worked so bought 5litres so I can do the rest. It has got rid of the black mold, bird poo, algae in fact everything. Spray it on be patient and it will work. My photo is proof.

This is the best stuff ever

Seems to be good Easy to mix one part to 4 parts water. Lucky I have a sprayer to apply. Need to pick a dry day to apply. So far the algae seems to disappear after application

Worked very well. I applied it using a sprayer about 5-6 hours before some light rain and by the next morning it had all cleared up and was moss free. This was applied to my patio and some decorative stones. Works well would recommend. It seemed to work faster than another brand I had used before. Also used 1:5 ratio.
