Waterproof ventilating type old wall ceramic tile retreading interface agent and using method thereof

Abstract

The invention discloses a waterproof ventilating type old wall ceramic tile retreading interface agent. The waterproof ventilating type old wall ceramic tile retreading interface agent consists of copolymer solution, 42.5 ordinary portland cement and fine sand, and a small amount of fly ash, water reducing agent, cellulose ether and PVA are added at the same time; a using method of the interface agent comprises the following steps of: (1) cleaning a base layer: cleaning floating dust, residues, oil stains and the like on a base surface of the well, preferably by using oxalic acid; (2) preparing the interface agent: mixing and preparing the interface agent according to the formula; (3) constructing the interface agent: constructing the prepared interface agent by using a spray gun or a roller, wherein the thickness of the constructed interface agent is 0.8 to 1.2 mm, and the construction is not carried out in rainy days; and (4) maintaining: after the completion of the construction, maintaining the interface agent for 12 to 24 hours and performing plastering construction.

Description

Waterproof and breathable old wall tile renovation interface agent and its application method technical field The invention belongs to the technical field of building materials, and more specifically relates to a waterproof and breathable interface agent for renovation of old wall tiles and its application method. Background technique Houses built in the 1970s and 1980s have been exposed to wind, rain, and sun, which have seriously affected the appearance of the building, and even caused water seepage on the outer wall, hollow tiles and falling off, etc., and must be repaired or rebuilt. Rebuilding will waste a lot of manpower, material and financial resources. . Therefore, the best way is to renovate the old wall and reshape the waterproof system of the exterior wall, which can achieve an aesthetic effect. If all the old wall tiles are removed and re-pasted, a lot of dust and noise will be generated, which will affect the life and work of nearby residents. Therefore, the...
