Polybonding concrete floor

r3nu4l

I need to put polybond on a concrete floor. I plan to use a roller to do so. Is there any advantage to wing the concrete first, before applying the polybond out should I only do it on a dry floor?

Also, I read somewhere that a floor should have a water: polybond ratio of 10:1. Is that correct?

Whats the project purpose: PB may not be the right answer
glad to see you can still type after getting the saw

No accidents yet, touch wood (though not while sawing )!

It's mainly just to reduce the amount of concrete dust coming off the floor. Not sure if polybond is the right stuff for the job but thought it would help...

The theory with the diluted polybond is so as it gets absorbed into the substrate, floor in this case.
If it goes on too thick, then it just forms a skin which will peel off and can also be somewhat slippy, especially if it gets wet.
So an initial couple of coats of 1:10 will get you started and then a couple at 1:5, I wouldn't go much stronger for reasons mentioned above.

Have you dismissed industrial floor paint on cost grounds?

The others here may have some better ideas, fingers crossed

Thanks, good tips there, I hadn't even considered whether the floor would get slippy, I've only ever used it on walls...

I was going to see how the polybond went first, then paint if I need to.

some handy tips there, thanks.

The PB may preclude industrial paint as it may need to bond directly with the concrete, I don't know, but if it is oil based...maybe an oil based primer would kill two birds with one stone, seal the floor and allow for industrial later, again just shooting the breeze here ideas -wise

jack of all

+1 regarding not using polybond if you want to use another coating later.

Where is the floor/ what's the room used for? If the existing concrete is clean, bare and has some surface roughness you could paint it with a polyurethane floor paint, which is very economical and easy to ease. I did a small floor area with a polyurethane paint from Castle paints in Tullamore. Only downside is it's only suitable for domestic/ light trade use. Advice I got from Castle Paints was that polybond preludes pretty much all coatings. Polybond is cheap and fine for dust-proofing concrete floors that will be covered over in carpet, lino or wood.

Glad I didn't just plough ahead with the polybond now! I've some research to do. Thanks.
