Are you considering covering your spaces with ready-to-use microcement and want to guarantee a perfect and long-lasting finish? If this is the case, the application of a microcement surface sealer and pore filler is crucial in any type of style renovation. This product not only protects the surface, but also ensures that the finish is smooth and aesthetically pleasing.
The use of a microcement surface sealant is essential in the preparation of supports after applying the polyurethane varnish. It acts as a primer that seals the pores of the base, preventing the ready-to-use microcement from absorbing moisture unevenly, which can lead to problems such as discoloration or premature degradation of the coating.
To delve deeper into how microcement surface sealant can enhance both the durability and aesthetic appearance of your areas, and to familiarize yourself with the most effective application techniques, we encourage you to continue exploring this Cementec article. Discover the significant impact that such a simple gesture can have on the longevity and aesthetics of your microcement surfaces.
Let’s start!
What types of sealants are there?
Thus, in the construction sector, sealants are classified into various families according to their specific properties and uses. The most common categories include:
- Silicones.
- Hybrids.
- Polyurethanes.
- Acrylics.
- Butyls.
However, in the context of microcement, a type of water-based sealant designed specifically for this application is preferred. This microcement pore-filling surface sealer, a one-component polyurethane consolidant, stands out for its ease of application, excellent waterproofing and durability.
Let’s immediately analyze this product from Cementec.
Microcement surface sealer closes pores Cementec Primer
n line with the above, Cementec Primer microcement surface sealer is essential for treatments on walls, floors and other areas coated with ready-to-use microcement. This product is effectively applied on previously sanded microcement and after the first layer of polyurethane varnish.
The use of Cementec Primer ensures uniform absorption of the support, which significantly improves the performance of the varnishes applied in later stages. In addition, it increases the impermeability of the surface and maintains the original colour tone, thus guaranteeing long-lasting protection and a superior aesthetic finish.
Advantages of using the surface sealer for pore-covering microcement Primer from Cementec
- Easy application: designed for simple and efficient application.
- Odorless: its low volatility formula prevents the emission of annoying odors during and after application.
- Mark protection: prevents marks from rollers and other applicators, ensuring a smooth and uniform finish.
- Resistance to yellowing: maintains its clarity without yellowing over time, preserving the aesthetics of the microcement.
- Hardness and impermeability: increases the resistance of microcement against bumps, scratches and water penetration.
- Colour stability: prevents changes in the tone of the microcement, guaranteeing the consistency of the original colour.
- Preparation for finishes: creates an optimal surface for the application of final finishing varnishes, improving adhesion and performance of the varnish.
What diference there are between primer and microcement surface sealer filler?
Bassically and for understand it well, the improvement and the sealer microcement surface fillers fulfil different roles in the surface finishing and protection process.
- First apply: It is used as the first step in preparing any surface, whether wood, metal, plastic, or masonry.
- Improves adhesion: increases the adhesion capacity of subsequent paints or coatings.
- Uniform base coat: provides a uniform surface that facilitates the application of subsequent coats, ensuring better adhesion and finish.
Microcement surface sealant:
- Final application: used at the end of the coating process to seal and protect the surface.
- Pore sealing: closes the pores of the microcement, protecting against humidity and other environmental factors.
- Colour protection and durability: helps maintain colour integrity and improves finish resistance to abrasions and chemicals.
- Varnish base: commonly precedes the application of polyurethane varnishes, which enhance the shine and durability of the finish.
What materials do you need to apply the surface sealant to the ready-to-use microcement?
The tools you will need to apply the Primer product, microcement surface sealer, are the following:
- Bucket.
- 22 cm microfiber roller.
- Brush.
- Measuring jug.
- Primer.
- Finish Forte or Finish Forte Plus.
To protect the areas that are not going to be covered, you will need the following materials:
- Corrugated cardboard.
- Black plastic to cover.
- Masking tape.
Likewise, the essential protective equipment consists of:
- Dust mask.
- Gloves.
- Protective cap.
- Knee pads.
- Appropriate footwear.
- Clean work clothes.
How to apply surface sealant to ready-to-use microcement
In effect, the application process of the microcement surface sealer or filler must be as follows:
- Once the microcement drying time has elapsed, apply the Primer diluted with 20% water with a short-haired microfiber roller. This product provides homogeneity and sealing for the subsequent application of Finish Forte or Finish Forte Plus products. Use the brush for more inaccessible places.
- Soak the roller well and wring it out to distribute it correctly throughout the microcement, to prevent drops from falling on the surface and the possible generation of “lies.” Apply covering the entire surface without leaving excess material.
- Once the minimum drying time of 3 to 4 hours has elapsed, begin applying the finishing systems: Finish Forte or Finish Forte Plus. Step by step application process you can follow here.
Tip: It is crucial to ensure that the microcement surface sealer is applied evenly across the entire surface. If any area is omitted, this could be problematic when applying the polyurethane varnish, as it can cause a change in tone towards a darker tone, thus interrupting the uniformity and aesthetics of the finish. If there is any uncertainty about the complete coverage of the sealer (“lie”), it is advisable to apply a second coat to ensure complete protection and avoid colour irregularities.
How many layers of surface sealant do you have to apply to microcement?
For microcement filler surface sealer, common practice is to apply a single coat of Primer sealer. However, to ensure complete coverage and avoid any unprotected (“lying”) areas, it is advisable to apply a second coat. This ensures uniform and complete protection of the entire surface.
How long does it take for the pore sealant to dry?
Finally, the drying time of the pore sealant generally varies between 3 and 4 hours, depending on factors such as the ambient temperature and the ventilation of the space where it is applied. To ensure complete and safe drying, it is recommended to wait at least 4 hours before proceeding with the application of polyurethane varnishes.
Conclutions
In summary, Cementec’s Primer microcement surface sealer stands out for being an essential and effective product, essential to ensure an optimal finish in any microcement coating project. Providing key properties that facilitate completion of the work with the highest quality standards.
Therefore, it is crucial to follow the manufacturer’s instructions exactly for the correct preparation and application of the sealant. Additionally, it is recommended to enlist the help of qualified applicators to ensure that the finish is not only aesthetic, but also durable and functional in the long term.
