[papercreters] Re: Acrylic paint in papercrete

Well to the best of my knowlage oil paint doesnt breath that is why you dont use it in extreem wet areas.and polyurithaine is used for metal i have only put it on brick once in 25 yrs of being in the painting trade.I would like to see the document where you found your info from.Deck coatings are stain and do not have a coating like oil or latex paint their for stain sinks in to create a seal.just my 2 cents worth.

To waterproof papercrete works a top coat of stucco could be used with an oil-based or polyurethane product. Oil repels water but acrylic is mostly water and dye....oil based paints would like beat off water the same way deck coatings are used to protect wood decks from water damage.
