Which primer is suitable for epoxy self-leveling flooring?
The principles of installation of cement and epoxy self-leveling floors differ significantly. For each of them, a different set of base materials, the number of layers, the need to use additional protective coatings, etc. is determined. But only one stage remains unchanged – priming the rough base before applying a self-leveling floor.
The primer or primer for epoxy self-leveling floor is responsible for three important tasks:
- Makes the surface layer more durable.
- Fills the smallest pores of the base to reduce the absorbency of the finishing material, and also fills small cracks.
- Improves the adhesion of the substrate to the polymers in the epoxy floor.
How to prime the base for a self-leveling floor?
The basis for choosing a primer is a set of properties of the rough surface. According to experts, the best result is achieved when using a primer for a self-leveling floor corresponding to the material used for filling layers. In the case of an epoxy self-leveling floor, it is best to use an epoxy primer.
An epoxy primer or primer helps in the preparation of concrete surfaces, as well as rough floors based on modifications of concrete, wood and other materials. It is the epoxy primer that demonstrates the best results of strengthening the concrete screed, protecting it from water and absorbing moisture from the finishing layer.
Typically, epoxy primers have a two-component composition based on epoxy resin and hardener, respectively. Primers that differ in composition come in different degrees of viscosity. The less viscous the soil, the better it penetrates into the pores of concrete or other material with a cellular structure, thereby improving its performance properties and further adhesion. Thicker primers can be used to level the base and seal cracks. Such primers can be used not only for epoxy self-leveling floors, but also for polyurethane ones.
Teknobond 300 – preparation of the base for the epoxy floor
To achieve the best adhesion with the self-leveling floor, to protect the base and the finishing layer from moisture and fungal formation, experts recommend using the Teknobond 300 primer. It is a two-component low viscosity epoxy primer without solvents in the composition.
This material has a number of important features:
- High penetrating power
- Excellent adhesive strength
- Versatility
- Ease of preparation of the mixture and its application
- Fast drying of intermediate layers
Teknobond 300 primer can be used to prepare concrete and cement surfaces for any subsequent work, as well as pre-priming rough substrates before applying epoxy self-leveling floors. A durable protective film is created on the surface, protecting the base from moisture penetration, which adheres well to the polymers in the composition of the self-leveling floor, ensuring the absence of gaps and places of moisture seepage.
