Floor paint construction specifications are as follows:
1, the original floor must have 3000psi or more strength, the surface of the whole flat, there shall be no sanding phenomenon, the water content of 8% or less before construction.
2, the ground level, flatness to two meters of horizontal ruler difference Shunping 2-3mm.
3, the floor surface PH value should be between 6.8-8.0.
4, the ground without oil, wax, paint, latex paint and other residues, if any must be cleaned with special solvents or polished clean.
Floor paint construction process
1, ground treatment
Floor paint construction first remove the surface of the cement mortar as well as adhering to the garbage and debris; floor surface hair, need to be completed with the grinder, and thoroughly cleaned; machinery and equipment below the grinder grinding position, need to use a steel brush to clean up. Position, need to use the steel brush to clean up; ground with oil stains on the part, need to use special methods to deal with clean; on the surface of the floor holes and obvious depressions should be putty to fill the batch of scraping, after drying, sanding and vacuuming.
2, primer construction
In the treatment of clean, flat surface, using penetrating solvent-based epoxy resin primer material closed batch coated once; primer material has a strong penetration, can penetrate the grass-roots level of the interior, to enhance the coating and grass-roots level of adhesion, which must be coated continuously, not intermittent, coated amount of the surface just saturated. The amount of coating should be just saturated on the surface.
Refer to CNS8083 requirements in 25kgf/cm2 or more. Quartz sand layer with epoxy resin (EPOXY) and 40-100 mesh quartz sand (natural quartz sand, hard and wear-resistant) mixed, fully mixed, will be stirred evenly mortar with a trowel flat spread on the primer, the formation of pressure-resistant quartz sand layer.
Epoxy resin mortar has fluidity, can fill the original ground depression in this construction process, make the ground more flat. Quartz sand has a hard, wear-resistant, pressure-resistant performance, quartz sand layer can withstand the floor due to the frequent movement of heavy objects on the floor of the crushing pressure, increase the service life of the floor. After the quartz sand is hardened, the quartz sand particles form a little bump, and the floor is smoothed by grinding machine.
3, medium coating construction
Visual inspection on the surface of the quartz sand layer after grinding to ensure that the floor wear resistance, pressure resistance, no collision, water, mineral oil, acid and alkali solutions, and adjust the ground level. With quartz powder and epoxy floor paint, as a medium coating, to be fully mixed evenly, scraping, this channel is mainly used to enhance the leveling performance of the ground.
After solid drying, such as pitting, cracks should be repaired first, and then sanded with a flatbed sander to make it flat, and vacuum clean. This time can make the ground more level, more convenient to find the ground still exists defects, so that the next layer of construction leveling. Floor paint construction surface layer in the coating is dry, epoxy floor surface coating, coating method with flat coating construction method.
If the party in the middle coating is dry, the first equipment installation and commissioning, resulting in the formation of new defects on the ground, the application of scraping material leveling, grinding, and vacuuming, cleaning and construction of the surface layer. With the prepared epoxy resin, filtered, with a trowel evenly spread in the middle coating, the formation of bright color self-leveling epoxy resin floor.
