Epoxy resin floor is a kind of high-strength, wear-resistant and beautiful floor. It has the advantages of no joint, solid texture, convenient maintenance and low maintenance cost, so it is deeply loved by users.

However, the general service life of epoxy resin floor is 8-15 years, but many epoxy resin floors are often in 2-3 years, or even in a shorter period of time there will be peeling damage of the coating.

Let's analyze the reasons for this kind of situation of epoxy resin floor coating!

1. Bulge and crack of epoxy resin floor coating:

The local bulge of epoxy resin floor coating is mainly manifested in the bulge with diameter of 2-5mm and 30-50mm.

The main reason is that the base is not dry enough, the gas gathers under the paint film, the surface of the paint film absorbs moisture and bulges, or the impurities are not cleaned when the paint film solidifies. There are cracks in the coating, which are shrinkage cracking of the coating and tensile cracking of the coating due to cracks in the base layer.

2. Peeling damage of epoxy resin floor coating:

There are two main reasons for the large area peeling damage of epoxy resin floor coating:

The first one: the interface between the epoxy resin layer and the concrete base is damaged, which shows that the epoxy coating falls off, the concrete base is normal and undamaged, and large area appears, the direct reason is the lack of interface adhesion;

The second is that the epoxy coating is closely combined with the mortar on the surface of the concrete base. The failure surface appears in the interior of the concrete base, and the failure surface is located in the mortar plane of the concrete base.

This kind of failure usually occurs in a large area, which is directly caused by the insufficient tensile strength of concrete. Different coating layers of epoxy resin floor coating also peel off, the main reason is the lack of adhesion between different coatings, which generally occurs in local areas, large areas are not common.
