Embodiment 1

[0033] Apply fluorocarbon paint to the exterior wall of a high-rise hotel for renovation, including the following steps:

[0034] (1) Clean the wall surface: clean the efflorescence part with oxalic acid; remove the peeling, foaming and pulverized parts with a spatula first, then scrub with a wire brush, and clean the floating dust with a brush to make the surface of the base layer clean and sturdy.

[0035] (2) Classify the cracks in the base layer: for the tortoise cracks less than 1mm, use an electric grinder to grind along the cracks, the grinding depth is 2-3mm, and the grinding width is 100mm. For regular cracks and tortoise cracks larger than 1mm, first use Open a V-shaped groove with a width of 16 mm and a depth of 8 mm along the crack with an electric polisher, and clean up the floating ash, then brush a functional reinforcing interface agent on the V groove and both sides, and fill the V groove after the interface agent is dry. Putty TB-998, after the putty is dry, ...

Abstract

The invention relates to a method for renovating an outer wall coated with fluorocarbon paint, comprising the following steps: (1) cleaning a wall face: cleaning up paint films of the wall face in saltpetering, pulverization, peeling and blistering; (2) classifying cracks of a base layer: for less than 1mm of a craquelure, polishing along the craquelure; for regular cracks and craquelures with more than 1mm, making a V-shaped groove along the cracks; processing the V-shaped groove by a bonding agent, plaster and a crack repairing agent to the V-shaped groove and two sides of the V-shaped groove and embedding an anti-crack cloth; (3) treating an interface of an old fluorocarbon paint base layer: evenly mixing the bonding agent with quartz sand and Portland cement, and roller-painting; (4) scraping anti-crack crosslinking slurry in batch on the wall face based on division blocks as units, and further hanging reinforcing ribs: after coating the anti-crack crosslinking slurry on the wall face, pressing the reinforcing ribs into the slurry; and (5) scraping the anti-crack crosslinking slurry in batch for the second time: making the total thickness of a dry film of the anti-crack crosslinking slurry be at least 1.5mm.

Description

technical field [0001] The invention relates to a method for renovating old fluorocarbon paint on the exterior wall. Background technique [0002] Fluorocarbon paint refers to the paint with fluorine resin as the main film-forming substance, also known as fluorine paint, fluorine resin paint, etc. Due to the high electronegativity of the introduced fluorine element and the strong bond energy of carbon and fluorine, fluorocarbon paint has particularly superior properties, such as: weather resistance, heat resistance, low temperature resistance, chemical resistance, and has unique non-toxic properties. Viscous and low friction. In recent years, there have been many fluorocarbon paint decoration projects in the exterior wall coating market. The general method is to use leveling putty or flexible leveling putty to scrape 2-3 times, and then scrape oily polishing putty 1-2 times, and then spray fluorocarbon paint base , middle and surface coating, due to the complex conditions ...
