Following is an introduction to the construction steps of epoxy floor: 1. Foundation treatment 1. Comprehensive grinding with a grinder. Let the damaged, sand-lifting, weak viscosity, cracking, empty drum parts completely exposed; and the floating mortar, old epoxy cement caking and other grinding flat. 2. Grounds with loose, cracked or delaminated surfaces must be thoroughly polished to a compact base, ensuring the cohesion of the ground 3, cleaning up the floating ash and pollutants on the base surface, and ensuring the cleanliness of the base surface. 4. Clean the treated ground.
Inspection method: After treatment, the floor surface is smooth, compact, dry, no oil pollution, and no loose and fragile particles, before the next process of construction can be carried out.
Special treatment for expansion joints, cracks, hollowing floors and loose old epoxy
1. Cutting slices into V-shaped grooves are used to repair and fill the cracks. Fine cracks can be repaired with epoxy resin and Extender T thickener. Fine cracks can be smoothed by hand grinder after solidification.
2. Cut hollow drum and loose parts of old epoxy, such as deep concave, use high-power medium-coated mortar to flatten them, and then grind them fine to flat after solidification.
3. All special sites should be cleaned once again after repair.
Methods of inspection:
A. The treatment of the above parts is an important part of the whole service life of the floor, otherwise it will lead to cracking of the floor.
B, after processing, and the entire ground level, the repair place without separation, dense, hard, smooth.
Two. Epoxy primer
1. Ensure construction before construction.
2. Mix the epoxy resin and the curing agent in the right proportion.
3. After mixing evenly, apply scraper or roller.
4. It is required to soak and strengthen the attachment force.
5, after the first dry, the epoxy coating will be applied again.
Three. Epoxy coating
1. Before construction, make sure that the floor is clean.
2. Mix the epoxy resin and the curing agent in the right proportion and add a certain amount of quartz sand to the ratio.
3. After mixing evenly, dump it on the ground. Use trowel to evenly trowel the material according to the designed thickness, so as to increase the strength and impact resistance, and make the ground stronger and more compressive.
4. After dry coating, the middle coating is ground and smoothed by grinding.
5, dust disposal is clean.
Inspection method: Whether the construction handover treatment is appropriate, the position of kick line is straight, no separation from the wall, flat.
Four, epoxy putty layer
1. After mixing the epoxy resin and quartz powder in the right proportion on the clean ground, the batch knife is used to scrape evenly on the ground to increase the combination between the middle coating and the surface layer and further adjust the levelness of the ground.
2, depending on actual needs, the number of construction is required to achieve smooth, non hole, no batch knife printing and sand grinding.
Inspection method: To make the ground completely flat without holes, no batch of knife prints and sanding prints before surface coating construction can be carried out.
Five. Epoxy coating
1, before construction should be kept clean.
2. First, evenly mix the B components of the surface coating material; then add the curing agent and mix well and stir well.
3. Use roller to evenly coat the material.
4. Once the first coating is dry and solid, then the second surface coating is then constructed.
5, self flow flat coated trowel scraping again.
6. Attention should be paid to the treatment of the successively constructed juncture.
Test method: uniform color, no hang, no pinhole, smooth and smooth.
