Installation Video 4: Apply Colored Epoxy Midcoat Quartz Sand


Colored Epoxy Midcoat Sand Layer is used to smooth the concrete floor,fill the cracks,joints,holes,etc., and it can improve the floor's impact resistance,compression strength largely.


Material:  CP-MA(Paint) , CP-MB (Hardener), Quartz Sand (60~100#)

Tool:  Spatula, Electrical Mixer


1)Open the tins of CP-MA and CP-MB,mix them based on A: B=5:1 by weight,stir for about 2 minutes by electrical driller;

2)Add quartz sand (80%~100% of the mixture of A and B) into the mixture, stir it for another 1-2 minutes by electrical driller. 

3)Pour the mixture on the primed floor, start to scrape it with flat spatula to cover &fill the whole floor. Corners,edges can be painted by brush. 

4)Finish the application within its pot life 20 mintues, and Maintain the floor for about 8~10 hours before the next layer.


Key Notes:

1),The consumption of CP-MA and CP-MB is 0.4~1 kg /sqm,depending on floor condition & designed solution;Quartz Sand is about 0.3~1kg/sqm according to design,generally ranging from 50%~100% of that of Epoxy.

2),You can do it one coat at one time or two coats at two times. The application interval is about 8 hours at 25 degrees. 

3),Before massive application, trial test is recommended,because you need to get familiar with the epoxy features. Open the barrels,take out ,for example,CP-MA 5 kg, CP-MB 1 kg to start mixing and add sand 3~4 kgs,

4),Epoxy thinner can be added to dilute the mixture for a better feeling of application,generally 5%~10% by weight would be ok.

Coating Layers:

Generally one layer of screed midcoat is enough. If there are flaws after the first layer, it's ok to apply the second layer.


The epoxy screed surface on floor must be dry,flat,sound,hard without bubble, crack or hole.
It should not be sticky to hand or tool.
All the floor surface must be covered without any leak.
