Internal wood waterproofing

[Draka]

I am building a SIPS (structural insulated panel) extension and am looking put a waterproof coating on the internal OSB wall and roof.

Can anyone tell me where I can get about 20l of gloss paint cheap or of good alternatives e.g. Everbuild 402 waterseal (which is designed for masonry) or Agricultural barn oxide gloss ?

Would either of those be suitable ?

Many thanks

You won't get it much cheaper than this.

Internal OSB its unlikely to get that wet so why not just buy cheap DIY store 'own brand' gloss? The boards will still have to be primed so why not use exterior grade OSB.
Don't use interior boards outside, hoping that paint will protect them!

It is external grade OSB but the gloss paint will add another layer of protection but also act as a sealent/vapour barrier, it has been suggested that some consider this good practice when using SIPS panels I am building a kitchen and bathroom I dont want to be ripping the tiles/plasterboard of 20 years down the track. I am probably being over cautious but better safe than sorry.

This was the exact same product I had been looking at, my concern was that any chemicals in it may damage the OSB's bonding glue/resin (probably not but wanted to check) and also wether there would be long term fumes given of as it is for internal use ?


I know few people know of SIPS but just consider it a OSB wall, I am sure there are plenty of people here who know a lot more about architectural paint than me.

Can anyone answer the question in bold ?

Thanks
