How To Densify Polished Concrete Correctly

[@calistiae]

this was an outstanding video to learn from. thank you. all the videos I've seen, the people are spraying a tiny bit with the sprayer. this is clearly not enough. I appreciate your insight and sharing this knowledge.

YOUR AMAZING KEEP UP THE GOOD WORK - LOVE THE EXPLANATION OF THIS PROCESS BEST I HAVE EVER SEEN

Great job explaining the application, how long should we let the densify dry? Overnight?

[@onelife69]

Most densifiers do work better the longer you can leave them, especially with softer floors that you've needed to apply many coats to. But we've successfully continued working within 1-2 hours of a light application.

What are disadvantages of densified concrete ? And how much it is expensive than epoxy/PU flooring ?

[@evansjackson4426]

When installing epoxy floors and you wanna densify the concrete. Which one do you do first. Polish then densify ànd right then the primers or you polish the floor again after the densifier for good concrete bonding with the primer

Great video! This weekend our mouldy carpet was lifted and the slab underneath ground, a sealer was applied but it seems many steps have been missed. Is it too late to apply a densifyer? How do we know if it's a soft floor?

[@onelife69]

If you can scratch the concrete easily or it visibly dusty then there's a chance that it'll be soft. You can use densifier at any time after the first 28 days of laying.

How do you suggest to have a polished concrete floor for blast freezer operations usually operating at minus 40 deg Centigrade

This is one of the best videos I have I have seen in which someone explain the principles of getting a nice concrete finish . Does your work cover small jobs ? I was thinking of using Diathonite Screed, as it has a heat retaining qualities with underfloor heating in a small extension? Would I be able to get a decent finish on it

[@onelife69]

It's not a screed I have used to be honest, so I couldn't how it'll turn out. If it sets hard enough and has good abrasion resistance then it stands a good chance of being polishable.

Thanks for the informative video. I'm looking to densify a white micro concrete wear layer (3mm thick) over a SLC levelled floor. I'd prefer the surface remain matt or satin, rather than gloss. I was looking at Everbuild (a Sika brand) silicate based 403 concrete hardener. It's about 1/3 the price of other products that are also silicate based. I'm wondering if it's a false economy. Will test first of course. Is your product suitable for ending with a matt or satin finish (so, could the floor be lightly sanded with say 120 grit afterwards to take away the gloss)? The other query is, is densifying a thin (albeit fibre reinforced and polymer modified) mortar layer (the 'micro concrete') a bad idea if the floor has encapsulated electric under floor heating? i.e. is it quite likely to break up if the surface becomes much harder, when subject to thermal expansion? Last query, in your view would a 5% SBR content (effectively 2% SBR solids), WRT cement, interfere significantly with the effectiveness of a silicate densifier?

[@thelist1372]

Any thoughts on a densifier/sealer like ps104 as a final layer on a garage floor? I'm thinking of sanding then sealing without polishing as it's a bit out of price range unfortunately. But it could be polished in the future right?

[@onelife69]

Hi there, it's not a product we've used, but if it converts the free lime into CSH then there's every chance it will provide a more usable floor surface with added protection. Yes you'll still be able to polish later on.

How would a densities work on a soft clay floor? Claycreat?

[@onelife69]

I wouldn't think this would work, sorry

[@chalmerelkins8965]

What about concrete countertop

[@onelife69]

Hi Chalmer, you can use a densifier on a countertop but as most countertop mixes have a very low water:cement ratio they tend to be very low porosity. So there maybe a chance that some densifiers will not penetrate fully.

What would you recommend to use in a jail where inmates are going to piss and crap on the floors?

[@onelife69]

You'd need some kind of topical sealer or resin
