Which Substrates Can Microcement Be Applied On?

Microcement is a versatile material known for its excellent adhesion properties, making it suitable for application on a variety of substrates.

Here are the main types of supports that microcement can be applied to:

 

1. Concrete

New Concrete: Microcement can be applied directly to new concrete surfaces, provided they are properly cured and free of dust, grease, and loose particles.

Old Concrete: For older concrete, it's important to repair any cracks and level the surface before applying microcement.

2. Tiles

Ceramic Tiles: Microcement can be applied over ceramic tiles after ensuring the tiles are securely fixed, clean, and free of grease. Joints may need to be filled and leveled.

Porcelain Tiles: Similar to ceramic tiles, microcement can adhere well to porcelain tiles with proper surface preparation.

 

3.Wood

Plywood: Microcement can be applied to plywood, provided it is stable, dry, and securely fixed. A primer may be necessary to ensure proper adhesion.

Hardwood: When applying microcement to hardwood floors, it is crucial to ensure that the wood is well-secured and free of any movements or vibrations.

 

4.Drywall (Plasterboard)

New Drywall: Microcement can be applied directly to new drywall after ensuring it is properly primed to enhance adhesion.

Old Drywall: For existing drywall, any damages or irregularities should be repaired and the surface should be clean and primed.

 

5.Plaster

Gypsum Plaster: Microcement can be applied over gypsum plaster surfaces that are stable, clean, and primed. Cracks or damages in the plaster should be repaired beforehand.

Lime Plaster: Similar to gypsum plaster, lime plaster surfaces need to be stable and free of dust and grease before application.

 

6.Cement Boards

Fiber Cement Boards: Microcement can adhere well to fiber cement boards, making them a suitable substrate. The boards should be clean and primed to ensure good adhesion.

 

7.Stone

Natural Stone: Microcement can be applied to natural stone surfaces that are clean and stable. Any loose or flaking parts of the stone should be removed and repaired before application.

Engineered Stone: Similar to natural stone, engineered stone surfaces need to be clean and stable for microcement application.

 

8.Existing Coatings

Painted Surfaces: Microcement can be applied over existing painted surfaces, provided the paint is in good condition and securely adhered. Any flaking or peeling paint must be removed, and the surface should be cleaned and primed.

Varnished Surfaces: For varnished surfaces, it is crucial to ensure the varnish is not peeling or flaking. The surface should be sanded to create a key for the microcement to adhere to.

Important Considerations

Surface Preparation: Proper surface preparation is crucial for ensuring good adhesion and a long-lasting finish. This includes cleaning, repairing any damage, and priming the substrate.

Stability: The substrate must be stable and free from movement or vibrations, as these can cause the microcement to crack.

Priming: Using a suitable primer is essential to enhance adhesion, especially on non-porous or smooth surfaces.

 

Conclusion

Microcement's versatility allows it to be applied to a wide range of substrates, including concrete, tiles, wood, drywall, plaster, cement boards, stone, and existing coatings. Proper surface preparation and priming are key to ensuring a successful application and a durable finish. By adhering to these guidelines, microcement can provide a seamless, durable, and aesthetically pleasing surface for various applications
