ProtectGuard Stucco

ProtectGuard Stucco is the result of plenty of hard work by the R&D department at Guard Industry. It is the ideal sealer for plaster, lime or cement based plasters, with or without organic binders. It has a strong beading effect and droplets slide off vertical surfaces. This ensures that all permanent spotting is prevented. ProtectGuard Stucco is a revolutionary product. It is an eco friendly, water based product. It is non toxic, solvent free, and silicone free. It’s main use is as a high performance Stucco, Marmorino, Marmorino Lustro, and Venetian Plaster sealer. It will protect such materials against water, oils and other stains.

ProtectGuard Stucco will do more than just keep out stains. It will also protect the plaster from the elements and slow down ageing processes. It is very UV stable and will not yellow over time. So it can be used indoors and outdoors. It makes cleaning much easier and is easy to maintain. Keep your expensive plaster looking great for many years to come.

ProtectGuard® Stucco is an impregnating product. It does not create a surface film. The substrate remains permeable to air. This is essential to ensure ongoing carbonation in lime based renders. It also means that moisture can escape from the wall as water vapour. ProtectGuard Stucco is completely colourless after application. It changes neither the look or the texture of the treated substrate.
