Acrylic high-performance shockproof multifunctional concrete varnish
Teknocila 300 is a one component, high-performance, shock-resistant acrylic concrete varnish based on an organic solvent used to seal, preserve and strengthen concrete surfaces. It is a varnish with a high degree of gloss and resistance to atmospheric phenomena. It has a high dry mass residue.
Teknocila 300 is applied to a cleaned, fat-free, dried and moisture-protected surface. It is used to protect concrete and other cement surfaces to increase their service life. Suitable for finishing vertical and horizontal surfaces. Suitable for protecting concrete surfaces reinforced with Teknoser topping. It is usually used on buildings and infrastructure facilities to increase the service life of concrete.

Foundation quality / preliminary preparation
The surface must be completely cleaned (including from fungus), degreased, dried and protected from moisture. Old coating layers must be removed mechanically. On fresh concrete surfaces, the varnish can be applied at least a month after pouring concrete. The film of cement milk, which prevents the adhesion of the material to the surface, should be removed by grinding. The manifestation of salts should be removed with a stiff brush, however, if it is intense and constant, the surface cannot be treated until the causes are clarified and eliminated.
Before applying Teknocila 300 acrylic varnish, mix well. It can be applied with a brush, roller or mechanical spray. It is recommended to apply the material in 1-2 layers to achieve a "wet stone". With each subsequent one, the gloss and density of the coating increases. When applying the material to a surface with a different structure or layers of different thickness, the shade may differ. After applying the material, the surface should be protected from rain for one hour.
To protect and finish concrete surfaces, special varnishes are often used, thanks to which a durable, protected matt or glossy surface can be achieved.Read article
