Concrete Plaster FAQs answer common questions about application methods, surfaces, durability, cost, sealing, maintenance, and design uses. This guide helps homeowners, designers, and contractors understand how concrete plaster works and where it performs best.
Concrete plaster is a decorative wall finish made from cement, limestone, and fine aggregates, designed to mimic the look of real concrete with either a smooth or textured, stone-like appearance. Applied by hand in thin layers, it’s versatile for interior and exterior walls, ceilings, fireplaces, accent walls, and other architectural features, offering a stylish, modern finish.
Concrete plaster is applied in thin, even layers with a stainless-steel trowel over a clean, dry, and primed surface. Apply two or more coats, allowing each to dry before the next. Once the final coat sets, the surface can be smoothed, textured, or burnished for a polished, natural, or pitted concrete look. Sealing enhances washability and eases maintenance.
Concrete plaster and microcement may look alike, but they differ in application, finish, and function. Microcements like Concretta are thin coatings ideal for showers and adhere to almost any surface, including tile. Concrete plaster is applied in thicker layers to create authentic concrete effects with stone-like textures, depth, and variation. Microcement is versatile, while concrete plaster provides a true-to-concrete aesthetic.
Concrete plaster can be applied to a variety of surfaces, provided they are properly prepared and primed. It works well on drywall, plaster, cement board, block, brick, and even previously painted surfaces, making it a versatile option for achieving a concrete-style finish in many interior and exterior applications.
Concrete plaster walls are low-maintenance, but proper care helps preserve their look. For routine cleaning, dust or gently wipe with a damp microfiber cloth. Avoid harsh chemicals or abrasive scrubbers. If the plaster is sealed, maintenance becomes even easier, mild soap and water can be used for occasional deeper cleaning.
Yes, concrete plasters can be tinted, but achievable shades depend on the type of concrete plaster. For example, Vega by Meoded, has a natural white base, and can be tinted to almost any shade, while concrete-base plasters like Golmex are better suited for deeper tones, as lightening is difficult. Selecting the right plaster ensures a consistent, vibrant, and natural-looking finish.
High-end concrete plasters made from both lime and cement are less susceptible to cracking when applied over a properly prepared, stable substrate. Cement-only plasters are more likely to crack due to reduced flexibility. Decorative plasters like Golmex and Vega by Meoded use limestone to minimize shrinkage and enhance durability, creating a smooth, long-lasting finish.
Natural, mineral-based concrete plasters formulated from limestone and cement are generally eco-friendly and contain 0 VOC, such as Meoded’s concrete plasters. In contrast, some cement-based plasters include synthetic resins, solvents, or other chemical additives, which can result in VOC emissions. Ultimately, whether a concrete plaster is eco-friendly and low-VOC depends on its specific formulation.
Yes, priming is essential before applying concrete plaster. The primer type depends on the surface: use PVA for new drywall, a multipurpose primer for previously painted surfaces, followed by a coat of Meoded Quartz Primer to ensure proper adhesion. Proper promotes strong adhesion, reduces cracking or uneven texture, and helps achieve a smooth, consistent, high-quality finish.
Sealing concrete plaster finishes is not always required, but it is highly recommended in many cases to enhance washability and protect the surface. A suitable sealer can reduce dusting, prevent staining, and make cleaning easier, especially in high-traffic areas, kitchens, or bathrooms.
Concrete plasters create a smooth, seamless finish with no grout lines, giving walls and surfaces a sophisticated, high-end appearance. They are highly durable and resistant to daily wear, impact, and heavy traffic. Concrete plasters like Vega by Meoded offer a wide range of colors and textures. When sealed, they are easy to clean and maintain, ensuring long-lasting beauty and performance.
Small concrete plaster projects may be suitable for skilled DIYers, but larger applications are best handled by professionals. The plaster powder must be mixed precisely for consistent color and texture, and with a quick drying time of 1–1.5 hours, achieving a smooth, even finish on large surfaces is difficult for beginners, while professionals can work efficiently within the timeframe.
Yes, concrete plaster can be applied over existing textures or old paint with proper preparation. The surface should be clean, dry, and free of loose paint. Glossy areas must be sanded, then primed with a Multipurpose Primer and Quartz Primer, or just Quartz Primer for flat paint. Textured walls may require a base coat to level deep grooves before priming.
Sealed concrete plaster is easy to maintain. Simply wipe with a soft cloth or sponge and mild soap, avoiding abrasive tools or harsh cleaners. Reapply a sealer every 2–3 years to keep it washable. Unsealed plaster is more prone to stains and moisture, so clean gently and address spills immediately; sealing helps protect and preserve its finish.
The cost of concrete plaster depends on the product and application. Decorative Concrete plasters like Golmex by Meoded is $167.75 per bucket, covering about 110 sq. ft. with two coats, while Meoded’s Vega costs $143 per bucket, covering around 40 sq. ft. Professional installation typically ranges from $12 to $15 per sq. ft., depending on project size and complexity.
Stainless steel trowels with rounded edges are ideal for applying concrete plaster, providing smooth, even coverage and helping to achieve a seamless finish. For decorative or textured effects, tools like sponge floats, patterned rollers, or concrete stamps can be used. Selecting the right tools help achieve a professional, high-quality surface that showcases the plaster’s versatility and aesthetic appeal.
