Sika SikaBond Exterior Grade Waterproof PVA – Suitable For Internal And External Use – Multipurpose – Easy To Use – 5 Litre

PVA is an amazingly useful liquid. It can be added used as a general purpose glue ( its the same as wood glue ) and you can also add it to fillers and plaster. It speeds up setting, increases stickiness, and increases hardness. It's excellent diluted as a primer for plaster and filler, and can happily seal dusty or fragile surfaces prior to painting or plastering. When it says waterproof it is not completely waterproof but it is substantially more so than ordinary PVA, which makes it far more suitable for applying under water based paint. Anyone who has used ordinary PVA knows that it's difficult to paint over with water based paints, but not this. It's also very useful for priming wood. Mix up a thick solution and it will halt moisture intake, prevent mould and so on. If I am making rough woodwork projects, workshop benches or the like, then I use this on raw unfinished wood as a sealant. It's extremely easy to apply, and you don't need anything else. I would not use this for exterior use, it's not waterproof enough. I would class it as water resistant. For waterproof need SBR.

Use this to waterproof outside walls to prevent damp inside. Effective

Did job perfectly. Consistency is great very water resistant.

It’s good

Excellent

Looks ok not used yet but for what I want it for its good

Better than builders merchants for price.

Was confused which one to buy as I was doing first floor bathroom tiles. I am glad that I selected this one as its less chances to water leakage from the floor. I have removed wooden floor and stick water proofing mat with this PVA and it works. Also added to tile mixture so it becomes cery hard within few minutes after applying the tile. Within 2 hours of tiling bathroom was ready to use. Definitely recommended to anyone.
