• Concentrated waterproofing admixture, ten times stronger than standard integral waterproofer
• Improves workability and plasticity of concrete, mortar and render
• Non-corrosive and chloride-free
• Retards suction in multi-layer renders
• Waterproofs rendering, roof screeds, pools, tanks, basement and reservoir walls
• EN 934-3; measured dosage bottle; single or box of 10

First, measure the dose from the bottle; squeeze the correct amount into the delivery nozzle.

Next, add the liquid to the gauging water of the mix rather than the dry materials.

Then mix and apply as normal. It improves plasticity so the mix is easier to work, and retards suction between coats in multi-layer render.

Finally, use it wherever water penetration is a problem. For surface waterproofing of finished masonry, pair it with our Waterseal; for below-ground tanking, see Tanking Slurry.

What does Power Proof do?

Added to the mix water, it provides integral waterproofing and improves the workability of concrete, mortar and render, for use where water penetration is a problem.

How strong is it compared with normal waterproofer?

It is a concentrate, around ten times stronger than a standard integral waterproofer, so you use less per mix.

Where would I use it?

Internal and external rendering, roof screeds, swimming pools, tanks, basement walls and reservoirs.

Is it safe with steel?

Yes, it is non-corrosive and chloride-free, so it will not attack steel in reinforced work.

How do I add it?

It comes in a measured dosage bottle. Squeeze the correct amount into the nozzle and add it to the gauging water.

Is it the same as a surface waterproofer like Waterseal?

No. Power Proof works inside the mix (integral waterproofing). Waterseal is a surface-applied masonry waterproofer. They can be used together for belt-and-braces protection.
