Substrate preparation

Proper substrate preparation is a fundamental step to guarantee the adhesion and durability of your microcement. Here’s how to optimize this preparation:

1. Cleaning the substrate: start by thoroughly cleaning the surface to remove any traces of dust, grease, or old coverings. Use soap and water for general cleaning and a degreaser for more stubborn stains. This creates a clean base for applying microcement.
2. Repairing imperfections: carefully inspect the surface for cracks or holes. These imperfections must be repaired with a suitable repair mortar to avoid later problems such as microcement cracking. Once repairs are done, sand the surface to ensure perfect uniformity.
3. Choosing the right microcement kit: depending on the type of substrate, you’ll need to choose between a kit for absorbent substrates or a kit for non-absorbent substrates, like those offered by Smartcret. Absorbent substrates, such as concrete or a cement screed, often require a specific pre-treatment to optimize decorative microcement adhesion. On non-absorbent substrates like tile, specific preparation is also needed to ensure microcement bonds properly.
4. Applying a primer: before applying microcement, it’s recommended to use a primer suited to the substrate type. For absorbent substrates, a primer that penetrates and consolidates the surface is ideal. For non-absorbent surfaces, a primer that creates an effective bonding layer is preferable.
5. Cleaning the substrate: start by thoroughly cleaning the surface to remove any traces of dust, grease, or old coverings. Use soap and water for general cleaning and a degreaser for more stubborn stains. This creates a clean base for applying microcement.
6. Repairing imperfections: carefully inspect the surface for cracks or holes. These imperfections must be repaired with a suitable repair mortar to avoid later problems such as microcement cracking. Once repairs are done, sand the surface to ensure perfect uniformity.

Protecting the work area

Before starting, protect the surroundings (floor, sanitary ware, faucets, and adjacent areas) with plastic or cardboard and masking tape. Next, apply the primer with a roller or brush, evenly, and let it dry completely (usually a few hours, depending on the product). This stage is key for a durable microcement application with no adhesion issues.

Mixing and preparing the microcement

To achieve an optimal result, it is essential to scrupulously follow the manufacturer’s instructions for mixing the components. In traditional systems, the process usually involves combining a powder component (A)—which may include cements, mineral fillers, and pigments—with a liquid binder/resin (B). This ensures a suitable consistency for application and a durable finish.

If you’re looking for a simpler, faster option, there are solutions such as Smartcret’s ready-to-use microcement. These pre-mixed formulas eliminate the need to measure and mix on site, reduce the risk of mistakes, and speed up preparation. In addition, they provide consistent quality and a homogeneous mix, making application easier even for beginners.

Whether you choose a traditional mix or a ready-to-use product, make sure the surface to be treated is clean, dry, and properly prepared before applying it. This guarantees optimal adhesion, good durability, and an impeccable aesthetic finish.

These two microcement approaches offer flexibility and options depending on your needs and your level of experience. Whether you're an experienced professional or a DIYer, microcement coating can aesthetically transform any space while also delivering long-lasting performance.

Applying the microcement

Applying microcement requires precision and care, especially to achieve a smooth, even finish that meets your aesthetic expectations. Here is a detailed guide to help you master the application stages, taking advantage of each tool’s specificities to customize the result:

1. Tool preparation: before you begin, make sure you have all the necessary tools. For textures and material effects, a polycarbonate trowel is recommended. If you’re looking for a “burnished” effect, choose a stainless-steel trowel. For a smooth, even surface, opt for roller application.
2. Initial application: start with the corners and edges using the polycarbonate trowel to apply a first thin coat of microcement. The trowel allows greater precision in hard-to-reach areas and also helps create interesting material effects through varied, controlled movements.

   The spatula will mainly be used to keep the trowel clean and to load microcement onto your main tool.

3. Spreading over large areas: for wider sections, use a roller to apply the microcement. This method is ideal for covering large areas quickly with a very smooth finish. Make sure the roller is evenly loaded and roll it over the surface with steady movements to avoid marks and buildup.
4. Drying and sanding: let the first coat dry completely; the time may vary according to the manufacturer’s instructions. Between coats, light sanding with fine-grit sandpaper may be necessary to remove small imperfections and ensure better adhesion of subsequent coats.
5. Applying additional coats: repeat the application process, choosing trowel or roller depending on the desired effect.

   If you’re unsure about the final effect, do a test on a small area. Taking the time before you commit will save you a lot in the end.

Remember, each coat should be as thin as the previous one. Wait for the previous coat to dry completely before applying the next. This ensures a flawless finish.

• Final check: after applying the last coat, carefully inspect the surface for any irregularities or defects. A final sanding may be necessary to perfect the finish before proceeding with the final protection of your bathroom microcement.

  Small reminder: make your finish choices before you start and trust yourself. Reserve the trowel for textured effects and the roller for smooth finishes. Keep it simple, follow the microcement application process, and you’ll turn your work into a true personalized work of art.

• Finishing and protection: once the microcement has been applied, it is crucial to seal it to protect the surface against water, stains, and wear. Use a suitable sealing product, applied with a roller or brush. Let the sealer dry for at least 24 hours.
• Final cleaning: after full drying, remove protective coverings and clean the workspace. For microcement, use a specific mild cleaner and avoid abrasives that could damage the surface.

This step-by-step guide with precise, structured stages will help you create an elegant, durable microcement walk-in or classic shower. It ensures you combine aesthetics and functionality in your bathroom renovation project.
