Coating before 24 hrs after washing

[Koehler87]

I'm in a time crunch, need to beat the cold weather in ny area.

There was still dust after grinding, power washed got it all off. Ive had two big fans going all night. Now I have a heater and a fan going. Looking to coat at 6 tonight that will be 20 hrs dry time total.

Will that be sufficient?

A solvent wipe would have been a better option rather than power washing. If it were me, I would wait a few days at least before coating it. Pressure washing your floor injects moisture which in turn causes hydrostatic pressure. This of course all depends on your temperature and relative humidity also.

Because i already tried the solvent wipe the pores were so full of dust. It made the floor feel Smooth. After I washed it all the pores were open and floor was rough again.

I see.. Usually a good vacuum removes all the dust from the pores, but I understand your situation. What is your weather like for the next few days?

I tried couple different vacuums, stuff was stuck. Here's a screen shot of my weather. Supposed to rain Saturday i know that day is out.

Which epoxy are you using?

 

[Koehler87]

Armorgarage epoxy chip. Manufacturer state 55 is the minimum temperature.

Ok, Armorgarage has multiple different epoxies. So you might want to call them and explain your situation and see what they recommend

I doubt pressure washing creates hydrostatic pressure. I went to water borne epoxy primer back in early nineties and have never had an issue with them after a wash down. See if they offer one compatible with your system.

Hi, if you rush coating over a floor that can still be outgassing from moisture you can end up with bubbles. Our suggestion is to apply the primer first and apply neat and tight (hopefully you are using primer). If that goes down without bubbles you should be ok.

Most epoxies can be applied somewhat colder than 55, they just take longer to cure. A space heater in the area can help wonders.
