Product Description


Concretta FS is a natural cement and limestone decorative plater designed to be in wet and humid areas such as showers, tub surrounds, and backsplashes. Concretta FS is a mineral plaster with an elegant, modern-day appearance that is both durable, breathable, and is ideal for interior/exterior applications. This plaster is formulated with superb adhesion that allows to apply directly over pre-existing marble/tile with no primer needed. This plaster finish has a seamless, smooth appearance with subtle movement and a luxurious texture. Concretta allows the creation of a variety of different textures giving walls a natural and authentic finish look of concrete.

Use a stainless steel trowel or spatula to apply two coats of Concretta FS

Surface Preparation:

New Surface – Surface should be clean and dust free. Prime the substrate with the recommended water-based primer as required; such as PVA primer for new drywall, multi-purpose primer for wood or glossy surfaces, and let it dry fully. Next, apply one coat of Meoded Quartz Primer allowing it at least 3-5 hours to dry. 

Existing Surface – Any surface with sheen should be sanded, dust free, and then primed with a multi-purpose primer letting it dry fully. Next, apply one coat of Meoded Quartz Primer allowing it at least 305 hours. to dry. Preparation of flat surfaces require only the application of Meoded Quartz Primer.

Shower Applications- Apply one coat of Meoded Quartz Primer over the waterproof substrate allowing it at least 3-5 hours to dry. When applying inside showers or moist areas, be sure to waterproof the substrate before beginning application as Concretta is only the finish coat plaster. 

Shower Tile/Marble – First, surface should be clean and dust free. Clean the grout lines to make sure there are no loose or flaking particles. No primer is needed when applying Concretta directly over tile or marble.

Exterior Brown Coat:

First, surface should be pressure washed and cleaned. When the surface is fully dry, apply Meoded Quartz Primer diluted up to 30% water. Let it dry for at least 3-5 hours.

First Coat:

Concretta FS should be applied thinly and evenly, covering the entire wall.

It is recommended to use a wet sponge or a plastic trowel in a circular motion before Concretta dries to create a more uniform design, expose the aggregate, and eliminate all imperfections. Allow at least 12 hours for the first coat to dry.

Second Coat:

Smooth Finish – Apply the second coat in the same manner as the first coat, but this time apply it a bit thicker to embed the large aggregate. Spread the material evenly maintaining the same thickness across the wall. For a smooth finish, smooth the wall with the trowel applying minimal pressure and cleaning off all excess material. If extra smoothing is needed, spray minimal amounts of water before the plaster dries and continue burnishing. Then, let the plaster dry for a minimum of 72 hours before applying a sealer.


Sealing and Clean Up:

Seal the surface after a minimum of 72 hours of dry time, clean up with warm water and avoid letting spillage to dry. Consult our team of experts for the best recommended sealer for your project.


Store material in a dry and dark place, void of humidity, protected against damage from weather and direct sunlight. Use within 10 months of production.


Mix 5 gallons (50 lbs) of Golmex powder with approximately 1.5 gallons (192oz) of clean water.
