Plaster Over Concrete Floor

Stucco italiano solido floor plaster is suitable for the residential market.

Plaster over concrete floor.

If you are applying with two people have one person dampen the floor and one person apply the thin finish. Spray the floor a section at a time. Stucco italiano solido floor plaster is a 2 3mm thick cementitious overlay which creates a luxurious natural smooth finish with a mottled look that matures over time. A venetian plaster floor can be patched re buffed or completely redone in the future if the owner so chooses.

Cut all mortar joints flush rather than tooling or sponge floating them. Using redgard under floor and wall tile will create a barrier that will be undisturbed after the tile is installed and grouted. Fortunately patching damaged concrete is an easy. But doing so is a very laborious time consuming process that is likely more trouble than it is worth.

A better solution is to prepare and resurface the concrete slab so that it can accept thin set adhesive or a mortar base onto which to lay tile. The process starts by grinding the concrete floor in order to remove contaminants smooth out the surface and abrade the surface to accept an overlay. The floors should be treated with care and good housekeeping is important. Though concrete is well known for its toughness it can degrade over time becoming marred with pits or cracks.

The floor can be hand troweled buffed and completed in just a few days. Concrete masonry provides an excellent base for direct application of portland cement plaster. Technically cement board can be laid over a concrete slab as the base for a tile installation. This layer is typically 35 75 mm thick and placed on water reed or straw over timber joists.

Concrete that was not properly mixed well when poured is especially prone to damage. The floor should always be damp before the thin finish is applied. While concrete is a strong construction material it can still crack. Gypsum plaster floors comprise a flooring layer that contains gypsum calcium sulfate as the binder mixed with aggregates such as crushed brick burnt wood and coal particles.

To enhance that inherent compatibility select open textured concrete masonry units that promote mechanical keying between the plaster and the base masonry wall. Wetting the floor will allow the thin finish to bond to the texture pave below.
