Patchy - that describes what my 1st coat looked like as well (I should really put up some photos). I had some of those pits after my 1st coat as well (in addition to my bubble issues). I think the 70% epoxy primer was a smart move. I assume you are doing a single-pass of epoxy-coat which will...

Thanks. I did give it a good sanding before filling the divots and will do so again before the next coat.

Nope no rain, and the humidity hasn't been high for the past 2 weeks. I spent the morning on my hands and knees filling grinding marks, bubbles and every other divot imperfection I could find with an epoxy crack filler. Not much fun but it should fix my issues with the floor after a little...

Things to consider: - Sawdust on epoxy is going to be slipery. Use mats around your workbenches and any machines. - Antislip grit will help, but make the floor more difficult to clean. Probably not too much of a concern if you are going to be using a shop vac or dust collector. - If you are...

A question for those with some experience... is it better to broadcast chips in a thicker or a thinner epoxy coat? I have the choice of either putting down two 5 mil coats or a single 10 mil coat.

Good luck today. The above DFT info should be a sticky. I made some similar calculations on Saturday and realized that I only put down a 4 mil thick primer coat which is why so many imperfections were showing through.

I did a test with a small batch for a 2nd coat and sure enough, some of the areas where the concrete has a small pit have again bubbled, fish-eyed or simply been left void of epoxy. I will be filling/patching each hole in the primer before I continue with the next coat. Many thanks for the...

In general, to convert between measurements of volume and weight, you must factor in the material density (usually given in g/mL or oz/cu in or lb/gal). Your mixing stick is clearly used as a proxy for volume while your scale is measuring weights. The mixing ratios may differ depending on the...

I sanded the whole floor today and have put a 2nd coat on the worst areas as an experiment to see how it looks. I think my expectations of what 100% solids epoxy would do were a little too high given the condition of the floor after grinding. The epoxy isn't leveling to fill what I originally...

Thanks everyone. I've decided to do another 'primer' coat of epoxy without flaking and then pickup a 3rd coat with more flakes on Monday. I don't currently have enough flakes for a heavy broadcast (I have 1 lb for 220 sq ft which would be pretty light coverage according to some other posts)...

Thanks. No acid washing and no pressure washing. Just used a hose and a stiff brush to remove all the ground away material. Used compressed air, a brush and an industrial vacuum after that. I ground the floor wet 6 days ago and it has been sitting since. I taped down plastic 48 hrs test spots...

Hi all. I'm using a 100% solids epoxy and was advised that I should apply 3 coats: The first works as a primer, add flakes to the 2nd coat and then anti-slip grit to the 3rd (clear). The floor was diamond ground, patched and well cleaned. Prep went well but after spreading the 1st coat I have...
