Tips for 4800 Industrial Floor Epoxy

4800 100% Solids Industrial Epoxy
Coating Over Concrete
4800 is an industrial grade epoxy that has great flow and leveling however it should not be applied direct to concrete. Be sure to use a primer suited for concrete before use.
Coating Large Areas
For large with widths of more than 30 feet it is best to maintain a wet edge by having 1 squeegee operator per 30 feet and 1 backroller per 60 feet of width. Also have a 1 mixing operator for every 3 squeegee operators. The idea is to start at one end of the facility and have all squeegee operators spread the material towards the other end while they are all working in infusion with each other to maintain the wet edge. Then the backrollers are following behind them on cleats backrolling the squeegeed material to a uniform level. Always plan starting and stopping points to be at joints in the concrete.
Using As a Build Coat Over Chip
Be sure to use the 4800 Non Yellowing material when using the 4800 as an inexpensive build coat over the flake. Do not apply the coating beyond the point where the garage door touches the ground. 4800 will yellow when exposed to normal exterior exposure so if you coat the outer lip of concrete beyond the garage door you can expect it to yellow. If needed use the final topcoat as the build coat for areas getting exterior exposures. Allow the 4800 to completely dry before top coating it. If top coating it with a waterbased topcoat then be sure to lightly sand the 4800 first.
Pot Life:
As is the case with most epoxy's yet more so with 4800, it is very important to keep the material cool and also to get it out onto the floor before it starts to exotherm (get hot and start to set up). Pour out the material into bands onto the floor and then begin spreading the material.
Accelerating:
Use 48 accelerator to increase the set time in cold environments. at 50 degrees 1 accelerator will cause the material to dry as if it were 70 degrees, use 2 accelerators at 40 degrees. Do not use accelerators to shorten the set time so the job can be done faster because this can decrease the adhesion and MVE protection.
Customer Comments:
F.Y.I. (from Shayne)
I recommended the 5205 as a primer coat under the 4195 for a monolithic floor.  Cliff of Hyteck painting advised that worked great.  The 4195 glided over the floor and it was so shiny that he thought it wasn’t dry after 45 minutes and had to touch to see if it was dry.  He also mentioned that he got better coverage out of the 4195 with that primer.  He thinks he is going to try the entire hybrid system on his next job, but he said he will not use the 4195 without that primer under it again.
