Golmex plaster is a high-quality Portland cement composed of lime, graded silica sand and admixtures to create the appearance of polished concrete on interior and exterior wall surfaces.
Our pre-mixed dry powder substrate is formulated for superb adhesion, workability, and durability. A wide range of interior and exterior textures can be achieved with Golmex; including the natural look of concrete and textured designer wall finishes from the hands of a skilled plasterer.
Avoid extended skin contact. Use eye protection and breathing apparatus when sanding material. Keep room well ventilated when working indoors.
Use a stainless steel trowel or a spatula to apply the two coats of Golmex.
Surface should be clean, dust and oil free.
Any surface with sheen should be sanded, then prime the surface with multi-purpose primer and let it dry fully. Next apply one coat of Meoded Quartz Primer allowing it to dry for 3 to 5 hours. Preparation of flat surface requires the application of Meoded Quartz Primer only.
Prime drywall substrate with PVA acrylic primer and let it dry fully. Next, apply one coat of Meoded Quartz Primer, allowing it 3 to 5 hours to dry.
Exterior Brown Coat:
Surface should first 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 to 5 hours. It is recommended to apply three thin coats of Golmex plaster over the brown coat to achieve a smooth surface.
– If the surface absorbs the material unevenly the final “look” will be different, (part of the wall is joint compound and the other part is painted drywall)
– If they are using 2 buckets for the wall, and mixing different amounts of water and mixing time varies, the cement will hydrate differently and cause the plaster to dry differently.
– If someone mixed 2 buckets of material and immediately use 1 and let the other bucket sit, he will notice the material has dried a little, you will need to mix more water to re-hydrate the material. Doing this will cause the material to dry to a different color. You must mix only what is needed and mix the entire material using the exact amount of water and exact amount of time in order to assure consistent color.
– People who use cement material, will typically spray water on the material while smoothing the surface, doing this will cause the a color inconsistency if different amounts of water are sprayed on different areas.
Golmex should be applied thinly and evenly, covering the entire wall. It is recommended to use a damp sponge in a circular motion over the surface while the first coat is still tacky to raise the grain and make the surface more even. Allow at least 12 hours for the first coat to dry.
Apply the second coat just like the first, while working in small sections.Use the metal trowel to gently compress the material, this will create a smooth even finish. The more you compress the smoother the material will be. You can use a spray bottle to spritz the surface while compressing to achieve an even smoother look, but the same amount of water should be sprayed on the entire wall to prevent color inconsistency.
Golmex can be left with a smooth or pitted finish, if a polished concrete look is desired, you can come back the next day and sand the surface with 220 grit sandpaper.
Golmex is a natural plaster and has its own characteristics, this can add a slight color difference on when the material dries completely.
To enhance the rich appearance of Golmex, glazing and sculpturing effects can be applied using standard plastering tools.
Sealing and Clean Up:
Seal the surface after a minimum of 48 hours of dry time, clean up with warm water and avoid letting spillage to dry.
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.
Golmex plaster comes in a standard cement gray color that can be custom tinted to darker shades with any universal and powder colorants. It can also be glazed with Meoded’s Velature Glaze, a color wash that provides a semi-transparent finish.

Depending on surface conditions, a 5 gallon container (50 lbs) of Golmex will cover between 80 to 140 sq. ft. up to an 1/8″ thickness with two coats.
