Preparing the surface before applying microcement
Proper surface preparation is essential to ensure successful microcement application. A clean, level, and well-protected base helps prevent imperfections and improves adhesion. Following these steps carefully will help you achieve a smooth, long-lasting finish.
1. Protect your workspace
Before starting, it’s important to properly protect the work area to avoid damaging surrounding surfaces.
- Use a plastic drop sheet to cover the floor and prevent microcement splashes.
- Secure the sheet with tape to prevent slipping or lifting.
- Apply masking tape to baseboards, corners, and sensitive areas for clean, precise edges.
- Remove fragile furniture and objects from the room to make application easier and prevent accidental damage.
2. Clean and prepare the surface
The cleanliness and condition of the surface directly affect microcement adhesion and durability.
- Thoroughly dust the surface using a vacuum or dry cloth to remove any debris.
- Degrease the surface with a mild cleaner if necessary, especially in areas exposed to oils or grease.
- Check for levelness, as an uneven wall or floor can affect the final appearance; if needed, use a levelling compound to even out the surface.
- Make sure the surface is dry and free of cracks; fill any imperfections with a suitable filler and allow it to dry completely
- Avoid unstable surfaces such as crumbling or poorly fixed materials, as these may compromise adhesion
3. Apply a primer
The bonding primer is essential to improve adhesion and prevent premature cracking.
- Choose a primer suited to your surface type (tile, raw concrete, drywall, wood, etc.).
- Apply a thin, even coat with a roller or brush, covering the entire surface.
- Follow the manufacturer’s drying time instructions—usually between 4 and 24 hours depending on the product.
- keep the primed surface clean and dust-free to ensure optimal adhesion.
4. Final checks before application
Once all steps are complete, do a final inspection:
- Touch the surface to ensure it is dry and not tacky.
- Inspect for any remaining irregularities.
- Prepare all your application tools so everything is ready when you begin.
Conclusion
Careful surface preparation is the key to a successful and long-lasting microcement application. Protecting, cleaning, levelling, and priming are essential steps to achieving a clean and durable finish. By following these guidelines, you’ll ensure the best quality results and long-term satisfaction!
