About to lay down 100% solids epoxy. no primer?

[JohnnyK81]

Hi guys. Covered my garage in Resurfacer (It was pockmarked) and purchased a bunch of kits of 100% Epoxy (Nothing special. From a local retailer in Canada. I ordered them in).

There is nothing about using a primer.

I know on cars, we can use reducer on epoxy and spray it as a primer/sealer before hitting it with full thickness.

Is this frowned upon for a floor with 100% solids? Should I just go gung-ho at full strength?

HAs anyone attempted what I suggest? I WOULD Like to use a kit or two to fill some low spots and ugly transitions but don't know if there is a max thickness I can apply it at (The datasheet and customer service is spotty at best).

Thanks guys!!

you are setting up for a marginal surface at best...

prep - acid wash and diamond grind for best adhesion.

The resurfacer needs something to stick to, chemically and physically - so it needs to be in the same family/maker as your epoxy.

Primer prepares the newly washed floor for the epoxy, again from the same maker/family of epoxy.

Reducer MAY be available, depending on the epoxy, but I would use it as the directions specify, doing anything else will be a **** shoot.

Most epoxy is not made to "fill" low spots, unless they are within the coverage specs of the epoxy, usually measured in thousandths of an inch for each layer applied, and there are restrictions on how thick each layer can be.

Were I you, I would return what you have and check with one or more of the known vendors here on GJ....All of them have proven to be leaps and bounds above the fray. And they know floors, epoxy and their products.

Hi there, thanks for the reply.

Yes I will be acid etching. My question was more regarding if 100% solids is ever reduced to be used as a primer before applying at full viscosity.

I have already extensively looked into the vendors here. It is too expensive now that our dollar has taken a tumble (Plus, I tell myself it's just a garage floor).

Hi,
You should be able to thin 100% solids epoxy with xylene to thin it and use as a primer....but TEST first small quantity to make sure it cures and such. Good luck.

 

[JohnnyK81]

So if it could be done would you recommend? Or just pour it on and squeegee it on as is?

Thanks!

I would never do 100% solids without a primer

If it is a repair coat that you will pull tight with a squeegee and coat again , then go for it.

Thin it out to make a looser and therefore more penetrating primer.

As Justin stated, I would never, ever apply a 100% solids epoxy onto an unprimed concrete surface.

Ever.

If you add solvent to it and pull it over pock marks, the solvent will want to escape as the material skins and you get tiny volcanoes. Primer will do the same.

Again, if this is a REPAIR COAT and you will PULL IT TIGHT with a squeegee, then you can get away without the primer. If any surface anomalies occur you can easily sand before next coat, it's worth the risk.

If this is a finish coat, then I agree with my colleagues, primer all the way!
