Epoxy floor paint base surface treatment methods

first step: concrete (cement) based ground handling:

1. first on the concrete (cement) basic area of the ground is uneven with epoxy resin plus quartz sand patch level, hard work polishing machine polished off a floating, obvious bulge, primer construction clean up can do. (Roughness, base no uneven surfaces can be polished directly on the ground clearing).
2. repair of concrete surface crack: available for thick crack repair material directly repair electric cutting machine for thin cracks should first cut about 1 cm wide seam along the crack, and then reinforced with fiberglass epoxy mortar + patch.
3. base surface strength C25, can't afford to not dusting powder, just grinding machine polishing, cleaning can be laid after epoxy floor coating.
4. basis of dust or powder on the surface: sand blasting or other mechanical treatment to remove floating layer and loose material, making the surface hard, rough and smooth. Then, use oxalic acid to acid-washed ground, repeated washing with water again thoroughly scrub the cement surface. Carefully check the grinding results, sanding again if necessary.
5. base surface dust or powder is very serious: it is recommended that relocating the 3-5cm cement screed and epoxy floor coating.


second step: Emery based ground processing:

Emery based surface is smooth surface, directly in surface layer construction of words will appeared adhesion not strong, easy off layer, first to on Emery surface layer for polished to surface formed a rough surface weizhi, again for epoxy resin to ping coating construction, put Emery surface layer polished into rough surface is to increased and ring oxygen material of adhesion prevent off layer.

third step: terrazzo based ground processing

terrazzo based ground processing
concrete based completed Hou surface polished of products on called terrazzo, it surface smooth, not can directly in surface layer laying epoxy resin to ping engineering, because terrazzo surface layer smooth adhesion not strong, easy off layer, to on terrazzo surface layer for polished to surface formed a rough surface weizhi, increased and ring oxygen material of adhesion prevent off layer.

fourth step: laying had not saturated resin to ping and ring oxygen to ping of based ground processing
laying had not saturated resin to ping and ring oxygen to ping of based ground processing live
with shovel knife shovel off old ping coating, polished cleanup clean Hou, on rugged of based ground with epoxy resin added quartz sand patch leveling, curing Hou for polished cleanup Hou do ring oxygen primer roll coated; flat degrees good, based ground no rugged of on can directly polished cleanup do primer construction can.

 
the fifth step: crack patch

for a heavy crack patch directly patch available for electric cutting machine for thin cracks should first cut about 1 cm wide seam along the crack, and then reinforced with fiberglass epoxy mortar + patch.
