OK, the floor is done. First up observations.
1. 1500 SqFt is an ass kicker!
2. Use proper PPE (personal protective equipment) when putting down the coating especially the paint respirator. The fumes are pretty heavy, you NEED a respirator! Use gloves, lots of them. Get a box of nitrile, latex or whatever but use them. You will go through a lot of them. Make sure you have a dust mask if grinding the cement.
3. Take the time to properly prep the floor. Grinding is the most preferred but also the most labor intensive. I did a chemical etch on the areas that the grinder could not get to.
4. Section off your work and lay the coating by sections. This helps determine how much is needed per section, and gives you a good feel for how thick it should be. I did not do this initially so some areas are heavier than others.
5. Use a hand held quart measure, painter's helper cup, and pour a quart at a time to work with especially the base coat. Don't pour a big glop on the floor, make a ribbon that you work with, it is easier and spreads better.
6. Use spikey shoe strap-ons, you will have to walk on areas where you have laid coating, you will need the spike shoes.
7. Clear coat is really friggin slick!!! Be very cautious when you walk on it with the spike shoes. The anti-skid ingredient, if used, doesn't work until after the floor dries.
8. Clear coat goes on a lot easier and quicker than the base coat.
9. If you grind and use water with the grinder, use two people. The slurry masks the area as you go so you lose site of where you need to grind. The second person can work the hose and help spray the slurry away so you can see what you are doing.
10. If you are dry grinding, get a good vacuum to help keep the dust down. Same issue with slurry, the dust will obscure the area so you can't see what you have done and what you need to do.
11. Make sure the roller you use is for epoxy/polyurea application. DO NOT use just a regular roller. You can get them at Home Depot or Lowes or order them on Amazon.
12. When using the anti-skid in the clear coat, always stir it well before applying to the floor. It is a heavy metal that will sink and settle, you need to make sure you keep stirring it before you scoop any up and apply it.
This is not a couple of hour project! It took me two days to grind the concrete and about a half day to remove all the dust and chemical etch the rest of the floor. It took me 7 HOURS to lay down the base coat. So basically, 3 1/2 hours for about 750 SqFt, it is very labor intensive and the base coat is the most challenging to lay down.
It took me only about 3 1/2 hours to lay down the clear coat as the base is relatively smooth so the clear coat glides on easier. It is a bit more difficult to see the areas you have covered with the clear coat, make sure you have good lighting so you can see the "sheen" of the freshly applied clear coat.
Pictures will follow shortly, they aren't a lot but they will give you the general idea.
