Method for retreading old porcelain brick wall by paint

Abstract

The invention relates to a method for retreading the old porcelain brick wall by the paint, a retreading decorative layer composed of a interface binder layer (2), a first polymer cracking-resistant putty layer (3), a second polymer cracking-resistant putty layer (4), a glass fiber girding cloth (5), a third polymer cracking-resistant putty layer (7), a double-component flexible putty layer (9), a smooth surface putty layer (9), a seal coat layer (10), a middle coating layer (11), a flexible silicone-acrylate latex paint layer (12) and a fluoric-carbon coating varnish layer (13) is formed on the old wall surface porcelain brick of the old wall (1), an anchor nail (6) passes through the glass fiber gridding cloth (5), the second polymer cracking-resistant putty layer (4) and the first polymer cracking-resistant putty layer (3) and is embedded in the old wall (1) for the mechanical reinforcement, all layers above are dried and solidified and are integrated with the old wall (1) firmly to complete the retread of the old wall surface. The construction cost and the labor strength are low, the old porcelain brick on the wall surface can not fall off, the decorative is high.

Description

technical field [0001] The invention relates to a method for renovating old wall surfaces of ceramic tiles with paint, which is suitable for renovation and decoration projects of various old wall surfaces. Background technique [0002] In recent years, incidents of cracking and falling of tiles, stones, face bricks, mosaics, etc. on the outer walls of high-rise buildings have often occurred. At the same time, after long-term exposure to the sun and rain, many old walls of existing buildings such as: All kinds of ceramic tiles, stone materials, face bricks, mosaics, etc. no longer have decorative effects, so the old walls need to be refurbished. At present, the renovation of old walls such as tiles usually involves knocking out tiles, stones, face bricks, mosaics, etc., and then repainting and decorating. The disadvantages of this method of renovation and decoration are: high construction cost, high labor intensity, and also affect the normal operation and use of buildings. ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method of renovation and decoration are: high construction cost, high labor intensity, and it also affects the normal operation and use of buildings.

In recent years, there has been a transformation method of painting and decorating directly on the old wall of tiles, for example, the method disclosed in Chinese patent application 01129004.8, but the potential safety hazard of tiles falling in the future has not been completely resolved.
