DE1958733A1 - Decorative concrete floor covering - Google Patents

Abstract

Decorative concrete floor is produced by placing a porous foil having a decorative pattern print onto the concrete and applying a self-hardening synthetic resin layer. The resin, which is pref. solvent-free and an epoxy resin, polyurethane or unsaturated polyesters, penetrates the foil to form a hard, smooth, wear-resistant layer in which the foil is embedded. Suitable foil material is paper or fibre fleece. Floor is for offices, terraces, balconies etc.

Description

Decorative concrete covering The invention relates to decorative concrete covering, e.g.

for cement screeds in basements, on terraces and balconies. It is known to make cement floors so attractive by painting that they e.g. can also be used for office space. It is also known the monotonous effect of such To loosen up the paintwork a little bit by placing small different colors in the paint layer Particles scatter.

The invention aims at concrete coverings, e.g. cement floors of any kind decorative effect.

According to the invention, a decoratively printed porous is on the concrete Foil and then a transparent, wear-resistant one that penetrates through the pores of the foil Layer of a self-hardening synthetic resin.

Porous film is understood here to mean any type of thin material, that is so porous that the plastic applied to it through the pores on the Concrete penetrates and can adhere to the concrete.

Such films can, for example, be made of paper, fiber fleece, fabric consist, the fibers being natural or synthetic, organic or inorganic Can be fibers. As a rule, thin foils come into consideration, however In principle, there is no limit to the thickness, provided the porosity is sufficient.

The synthetic resins used are predominantly solvent-free or low-solvent self-curing resins Synthetic resins into consideration, in particular epoxy resins, polyurethanes, unsaturated polyesters, which can be applied in liquid form and easily due to the addition of a hardener harden quickly.

The drawing shows a cement-concrete slab as an exemplary embodiment according to the invention.

Fig. 1 shows the plate in a perspective view.

Fig. 2 shows on a larger scale a section through the plate.

The plate shown in FIG. 1 may have a length and width of 1 up to 2 meters and a thickness of a few centimeters. She likes cement concrete exist.

On top of the plate 1 is a thin with a decorative Pattern printed fiber fleece 2 placed and then with a solvent-free reactive synthetic resin has been coated. The synthetic resin is through the pores of the nonwoven fabric reaches the concrete and is then hardened so that it is above the nonwoven fabric a transparent, wear-resistant layer 3 forms. The invention relates to not only on slabs that can be laid, but especially on floors as a whole Seamlessly covered with printed porous foils and then with transparent self-curing Are coated with synthetic resin.

The film thus only represents the carrier of the decorative pattern while the synthetic resin allows the pattern to be recognized undisturbed and creates a hard, smooth, forms wear-resistant layer.

The manufacture of such a decorative concrete covering is simple: The printed porous film is placed on the carefully cleaned concrete surface or glued on and then the liquid synthetic resin mixed with hardener as thin layer applied.
