Concrete Repair Fine: How to Prepare a Perfect Surface for Exposed Concrete Paints?

The Key to Perfect Surface Preparation for Exposed Concrete Paints

As an essential material for modern architecture, exposed concrete stands out for both its durability and aesthetic appeal. However, proper surface preparation is essential to reveal and preserve this character. This is where Bautera Concrete Repair Fine comes in. So, how can you achieve the performance expected from exposed concrete paints? The answer lies in perfectly preparing the surface with Concrete Repair Fine .





Why is Surface Preparation So Critical Before Concrete Painting?

Silicate-based paints work by forming a chemical bond with the concrete. For this bond to be strong and long-lasting, two things are necessary:


1- A Solid and Clean Substrate: No matter how good the paint is, if there are cracks, dust or a weak layer on the surface underneath, the life of the coating will be short.


2- A Smooth and Porous Structure: Silicate paints penetrate the pores of concrete. A rough or irregular surface can result in an inhomogeneous appearance and color deviations.


Concrete Repair Fine is produced to meet exactly these two critical needs.





Concrete Repair Fine: The Perfect Repair Material for Exposed Concrete

Concrete Repair Fine is a cement-based, thin-coat repair and leveling mortar that ideally conditions the surface before applying exposed concrete paint. Here are the features that make this product indispensable for exposed concrete paint applications:


- Perfect Correction with Thin Film Thickness: Can be applied in thicknesses ranging from 0.5 mm to 4 mm. This covers fine cracks, pits, and roughnesses on the surface, creating a perfect base on which to apply your exposed concrete paint smoothly and homogeneously.


- High Adhesion and Durability: Thanks to its resistance to water, frost, solvents, and abrasion, creating a durable and reliable primer is essential for the paint to be applied. The lifespan of the paint is as long as the repair that prepared the exposed concrete.


Breathable and Bubble-Free Surface: Concrete Repair Fine 's bubble-free structure ensures a smooth surface. It also allows the concrete to maintain its breathability, preventing moisture and swelling problems in coatings made with silicate paints.





Concrete Repair Fine and KEIM Concretal-Lasur: A Perfect Technical Match

KEIM Concretal-Lasur is a silicate-based, translucent paint that enhances the natural appearance of concrete and exposed concrete. When used in conjunction with Concrete Repair Fine, it creates a perfect synergy in technical and aesthetic terms.

- Chemical Compatibility: Both products are mineral-based. The cement-based surface prepared by Concrete Repair Fine forms a seamless chemical bond (silicification) with Concretal Lasur 's silicate binders. This creates an extremely durable system that works as a single layer.

- Aesthetic Integrity: Concrete Repair Fine smooths the surface without altering the concrete's characteristic texture. Concretal-Lasur applied over it creates a homogeneous color transition across this smooth surface, fully revealing the concrete's natural texture. Paint doesn't conceal the concrete's essence; it emphasizes it.

- Long-Lasting Protection Cycle: Concrete Repair Fine ensures structural integrity, while Concretal Lasur adds superior protection against UV rays, weather, and moisture. This combination delivers performance that lasts for years.

Lay a solid foundation with Concrete Repair Fine , protect it and make it aesthetic with KEIM Concretal Lasur .
