Concrete sealer/primer

sonic85

Hows it going? I want to paint a garage floor and I was just wondering if anyone has any recommendations for primer or sealer of some kind to keep dust down and so the paint adheres properly to the cement?

I was going to go with something like this but I dont know if its suitable

Yep, you need to water it down a good bit.

What kind of paint did you intend to use on your concrete floor, most of the 2 pack epoxies and polyurethanes recommend that only a thinned coat of that coating is used to prime the concrete. In other words if you use PVA you may not be able to use these type of coatings, you may have to stick to the water-based alternatives. I used zylene with 2 pack epoxy as a primer/ first coat. With ployurethane I used white spirit for the first/ primer coat. Do your homework on what paint you intend to use and follow the instructions as regards primer. Just my tuppence worth....

I have the paint but not sure what it actually is! Its quick drying synthetic paint of some description and one of the main ingredients seems to be white spirits. Would my best bet be to give the concrete a brush down with white spirits first then? Thanks for the replies!

What do the instructions on the can say? If no information there see if there's a contact email for it- that's what I did when using those products and the manufacturer was happy to advise. White spirit clean-up IMPLIES white spirit as a thinner.

Theres nothing on the cans besides a list of ingredients so I'll send an email to the manufacturer and see what they say. I'll have to give the cement a powerwash first anyway because its filthy so I have time!

What's the brand of the product, any photos? Don't overdo it on the powerwashing- the concrete will need to be bone dry before coating with any floor paint, would be a good idea to run a dehumidifier if you are going to soak it.
