All kinds of SOLVENTS mainly plays dilution and is dissolved into membrane substance, reaches working viscosity, is easy to construction.
Construction technology is:
A. processing base level: before base treatment, concrete wall needs the maintenance of certain hour, and the curing time in general new cement wall surface winter is 28 days, and the curing time in summer is 14 days.Maintenance is arrived the pH value of basic unit less than 10, and water ratio carries out processing base level again after 10%.Should thoroughly remove loose, peeling, hollowing, atomizing basic unit, remove pollutents such as dust, greasy dirt.
Base materials such as ceramic tile, marble, metal must carry out necessary polishing to be handled, and thoroughly removes loose, peeling, hollowing, atomizing basic unit then, removes pollutents such as dust, greasy dirt.
B. elastic metallic luster coating: press component 1: component 2=8: 1 mixed is good, converts 20% special diluting agent again and dilutes.Directly evenly spray on the object plane, generally spray twice.In order to make protective material reach good perviousness, back one time and then last time directly spraying must pitch time.Spraying must put in place, and the spray of leakage and uneven phenomenon can not be arranged.With joining with usefulness, the same day, allotment will use up in 4 hours after preparing in the use.
Elastic metallic luster coating of the present invention belongs to the solvent-borne type product, and service tool cleans with special diluting agent and gets final product.
Through specific embodiment, the present invention is described further below.
