Inadequate preparations for the construction of floor paint, easy to cause sand, powdering so that the surface pull strength decreased, or poor surface treatment, the ground oil and other objects can react with the floor paint, thus affecting the adhesion of floor paint caused by the floor shell. The water content of the grass root is too high, it will also affect the bonding of the paint film, handle the substation, can avoid the surface shell, bubbles, de-layering and other ills to a great extent.The requirements of floor paint construction on the base surface
1, the grass-roots surface must be dense, no loose, sand, de-layering phenomenon;
2, floor concrete strength finally reached C25 or more, surface pressure of more than 60Mpa;
3, grass surface flatness reached 2 meters, straight-foot test high and low drop difference is not greater than 3mm;
4, the first layer of epoxy ground construction, should first carry out ground moisture treatment
the requirements of flooring paint construction on the space environment
1, construction site floor piles, engineering waste and construction equipment clearance;
2, other construction team evacuation operation area, in the floor paint construction area non-construction personnel and vehicles are not allowed to enter;
3, wall, top wall must not leak, seepage phenomenon;
4, construction area to ensure adequate lighting, to ensure that construction personnel have a good line of sight;
5, construction area has good ventilation facilities, to ensure that the construction or post-construction air flow, help paint layer drying, shorten the solidification time.Front ground treatment
1, for cement or hydrate ground oil (cooking oil, oil, etc.), first with sodium hydroxide (commonly known as soda) sprinkled on the surface has been wet with water, with bamboo broom repeated scrub, and then rinsed with water, can be repeated 2-3 times, until the surface is oil-free. Construction personnel should wear long water boots, wear rubber gloves to operate, in order to prevent soda corrosion of the skin.
2. For ground with old paint, if the paint is prone to shelling, falling off, or reacting to paint, it must be completely removed or polished before construction can take effect. If most of the paint surface adhesion is good, and does not react with the floor paint, then first remove the easy to fall off part of the paint skin, and then use a grinder or hand-held sandpaper to coat the surface of the old paint, in order to enhance the inter-layer adhesion of the new paint.
3, not very flat, there are cement lumps, floating cement slag on the ground, first with diamond water mill polishing, and then cleaning, vacuuming.
4, for deep telescopic seams, must first be filled with color elastic glue to a height about 1-2mm below the ground plane, and then with fast-drying hard paint putty scraping flat;
5, for wet or part of the water and urgent need for construction of the ground, to take water absorption, drying, sunlight, hot fan blowing or gas flame burning and other measures to speed up drying, in order to meet the construction requirements.
