Agree with LegacyIndustrial. Grinding it first will get the loose stuff out and then use some kind of patch. I use a cement based floor patch and then coat the floor. The problem with pitting like that is it can disintegrate if you don’t grind it out. You can’t just coat it or patch it.

Most rental units ****. I have the Husq PG450 and it barely does the job. Check bigger concrete supply companies for rentals. It ***** because it’s expensive, but in the world of floor prep, it’s either done cheap or done right. You can always hand grind with a 7” grinder and a cup wheel. That...

I shut the garage door and trace the weatherstrip with a pencil. Open the garage door and cut that line with a grinder and a diamond cutting wheel about 1/4” deep. Let your epoxy flow into the cut and fill it up. It is a sharp line and is a much stronger edge than using tape.

Hypothesizing... I get $1.00-$1.50 per square foot to grind floors. 400sf with the cracks and putting would put you at $400 for prep. Prepped with a 7” hand grinder and diamond cup wheel, cracks filled with a cement based patch. My partner gets about $1.50/sf to paint, throw flake, and clear...

My partner tells me it’s just fine, I wanted some other professional opinions. I appreciate it!

I can’t always wash them out because my partner may need come and paint right away, no time to wait for it to dry.

It’s not a pretty answer, but grinding those spots is the most assured way to get the epoxy to stick. Anything else and it may or may not stick.

Late to the party here, but I am spreading the word. I have owned a Husqvarna PG450 for 3 years and it’s worthless!!! The rental places have the 110v model and I have the 220v model.

Don’t rent a 110v Husqvarna PG 450. I have the 220v model and it’s garbage!!! The 110v model is a joke. A very expensive joke.

Hey all, new to the boards. I prep 3-4 floors a week for epoxy. My partner and I are both professional Firefighters and do this on our days off. We haven’t had any issues with our floors after we are done. With that being said, I obsess over how much remaining dust is ok. I use a 7” hand...

You can just re grind the areas where your tires were. Make sure water absorbs very quickly again to make sure you got it all.

It happens man...always! If you ground it, just get it coated and your flake will cover any tiny imperfections. I sweat the small pop outs and I prep about 3 floors a week. My partner paints them and shows me how I am obsessed over nothing!!

Ivinjacob, hate to say it, but that still looks too shiny. Acid etching doesn’t always guarantee a proper “cut”. You may have to redo some spots. Grinding is simpler. It’s a lot harder but it opens the pores better.

Lots of cheap cat litter or floor dry. Step on it and it will crush and turn to dust. Leave it sit a couple days if you can. Sweep it up and spray brake parts cleaner on the area and wipe it with a rag. I did this procedure and then ground it for epoxy prep. 3 years so far with no issues.

We just make sure the saw cuts are scratched up really well if you can’t remove the current paint. I have a Husqvarna PG450 and it’s worthless especially at removing paint. I use a PCD diamond blade on my 7” grinder. I use a Dustbuddie dust shroud with an Ermator S26 vac. If you use a shop...
