Interior Finishing and Backgorund preparation

Prependuit and Decofond

Concrete blocks, plasterboards, wooden boards, cement plasters, bricks, tiles etc. can be prepared with PREPENDUIT applied DIRECTLY to the background to obtain a surface to which a finishing coat/s is applied (normally a coloured finish with Color Chausable in its medium, fine or extra fine granulometry), depending on the texture required. A traditional lime plaster can also be applied on Prependuit. See ONE COAT USER GUIDE

On the same surfaces DECOFOND is used as a preparation coat for lime washes or fine coat finishes (for example stucco and marmorino). These can be applied directly on DECOFOND.

Lime Paints

These are traditional lime washes to which 5% SBR has been added for longer life and less powdering. In new build or on refurbishing these are best applied on a lime undercoat applied directly on the surface prepared with DECOFOND.

Polished finishes

Stucco, marmorino finishes are beautiful finishes, easily obtained with DECOLISS on a background prepared with DECOFOND. If a straightening coat is required use a NHL 3.5 at 1:3 with fine aggregates (not more than 1mm) or EcoMortar F before applying DECOLISS.

Traditional lime plasters are achievable also in new build. Once completed, they provide a very attractive setting whether painted or not.

The requirements and building materials of contemporary building are however different from the past but by using the St. Astier preparation products it is possible to achieve the traditional style finishes and effects even on surfaces that would normally not be suitable.
