As the saying goes, a good start is half the success, and so is the construction of the floor. The preparation before the approval of epoxy sand floor paint material affects the bonding degree of the base and epoxy sand paint and the length of life of the floor. Whether from the environment or construction should pay attention to strict control, to meet the following requirements
china
.
, the grass-roots pre-construction requirements
1, construction personnel before entering the site, the water content test, to determine the ground water content rate of less than 8% of the construction standards. If not meet the requirements, need to set up moisture-proof layer, can carry out grass-roots construction.
2, the grass must be reinforced concrete structure, strength level can not be lower than C25.
3, if it is the old floor refurbishment, the construction personnel need to use cleaning tools will be the original ground loose layer, cement stains, lime film and other foreign objects.
, the grass-roots construction requirements
1, the new ground grass-roots initial condensation, to determine the bureau tribal differences, the use of a grinder to polish the raised part.
2, if the old ground, to first use the grass-roots repair materials to repair the ground larger grooves and cut seams.
3, the use of dust-free grinding machine to polish all the ground, raw pulp surface, machine lighting, in order to achieve flat. Finally, use a vacuum cleaner to suck the ground and corners clean.
, after the grass-roots construction requires
1, concrete ground grass-roots treatment in summer needs at least 28 days of maintenance time, winter appropriate extension.
2, before the construction of epoxy paint, the grass surface should be kept clean, not allowed to have pollutants. All contaminants such as fat, grease, paint residues, chemicals and syrup must be removed.
, the construction environment requires
epoxy-colored sand floor construction temperature should be controlled at more than 5 degrees C, relative humidity should be controlled at less than 60%. The water content of concrete should be less than 8% to ensure the binding strength of epoxy resin coating with concrete substation.
the above requirements are epoxy sand floor paint pre-construction preparations, to know the epoxy sand floor paint construction process, please see the next decomposition.
