In this regard, it is important to note that there are strict construction standards in this case, and there is an excellent comparison table in this regard, as long as you follow the comparison table.

Construction, there are still a lot of his flat screens, and we will all get better use, and we should take him to divide it in time. Now,

The standard body size is not the same, and the cars that require noodles are on the back shelves, and the face without regrets is also.

Also raising his land, average his level, his Libina construction, his standards are still very accurate, and able to bring him mobile empty numbers.

Epoxy flooring has construction standards for cement floors, and I think there are still many standards like this, so I think you can check it on the Internet.

The construction standard of epoxy flooring for cement flooring, I think that if there is a standard like this, there will be many requirements for this standard on the Internet, you can take a look.

This requires some professional knowledge, and how much is the customization of a standard for this aspect of the country?

The main materials are epoxy floor primer, intermediate paint, topcoat, quartz sand, etc., which will be configured and produced by these urban professional manufacturers, and there are many small materials to buy.

Epoxy floor coating is a kind of high-strength, wear-resistant, beautiful floor, with no joints, solid texture, good chemical resistance, anti-corrosion, waterproof, dustproof, easy maintenance, low maintenance cost and other advantages. A variety of schemes can be designed according to different application requirements, such as epoxy thin coating flooring, epoxy thick flooring, 1 5mm thick epoxy self-leveling flooring, anti-slip and wear-resistant coating, mortar coating, anti-static, anti-corrosion coating, etc. Epoxy floor coatings have been used for functional flooring since the beginning

Such as anti-corrosion, wear-resistant, anti-slip, developed to the general general industrial floor; In addition to the functional requirements, it also has a decorative effect.

Since its introduction in China, epoxy resin flooring has been widely used in all walks of life, and has played a significant role in the production of enterprises with high-quality performance. Let's find out together.

1. The cement foundation surface is required to be firm, strong and not shelled, and it is best to pour cement and concrete bottom together to prevent the mortar layer from crusting, and the concrete foundation is dry for 28 days. The ground on the first floor needs to be waterproofed.
