At the time of the replacement of the old and the new, the biggest problem we are facing is not how to choose a better epoxy floor, but how to remove the waste epoxy floor paint. This is often more difficult, the construction period is large, and will bring many problems. Our company in the long-term construction process, summed up four commonly used clear methods, to introduce to you, I hope there is a need for it. People are helpful. Before that, we should look at the situation of the old floor. If the epoxy floor is damaged in a small area, we only need to remove the partially damaged coating, retain the intact coating, and then repair it with the same color epoxy resin material. If there are serious conditions such as scaling, foaming, corrosion and cracking in a large area of the floor, we need to remove all the coating on the whole floor surface until the base is exposed. Material, then coat the appropriate floor. 我们经常会用到的几种除漆方法如下：
Several paint removing methods that we often use are as follows:
I. Mechanical Paint Removal
Mechanical paint removal refers to the process of removing paint by means of a certain construction machine, such as manual polishing, shot blasting, high pressure (abrasive) jet and other methods, which can effectively remove the old floor paint layer.
2. Flame Paint Removal
If the bond between the old floor paint and the base is firm, the floor can be heated by flame to make the old paint coke and foam, and then eradicate the old floor paint with a scraper. This method is called flame paint removal.
3. Paint Removal by Alkali Solution
Alkali solution paint removal method is to use the corrosion of alkali solution to make the old paint film swell and soft, so as to achieve the purpose of removing the old floor paint film.
IV. Paint Removal Agent
Paint remover can dissolve or swell the coating. It is an economic or paste, mainly composed of solvent with strong dissolving ability, paraffin, cellulose and so on.
In the floor coating industry, the main mechanical methods of removing old coatings are hand-baked shovel, shot blasting and so on. If the previous floor primer is epoxy or polyurethane paint, there are many kinds of coatings that can be matched, most of them can be directly painted on it; if the primer uses one-component acrylic acid or other volatile paint, if you choose floor paint to paint at will, it will be easy to bite the bottom of the situation, when painting must be done. Choose paint carefully. If we need to build epoxy flooring on new ground, we must choose a regular company to design the construction plan. We should not choose the wrong flooring material because of greed for cheapness. Otherwise, there will be quality problems in the short term when the flooring is completed. We must remove the old film layer and make a new epoxy flooring. In this way, we will pay a greater price.
