To remove a resin based curing agent off a hardened concrete floor?
Hi please help!!
We have installed a power floated concrete floor with a light grey floor hardener. The concrete floor came out great and we applied a resin based curing agent. Now 3 months down the line the client wants to paint the floor as the resin curning agent has stained the concrete floor where it has been applied to thickly. You can clearly see the markings. Normally this will work away as soon as you get some traffic on the floor, but this is not the case as it is a resin based curing agent. We want to strip the curing agent (becuase it did it's job) and leave the floor looking uniformly great as it is. I'm left with two options, either strip the curing agent with a floor scrubber/polisher that they use in the supermarkets to clean floors or use our Husqvarna P820 with resin pads to strip it and polish it up at the same time. The supplier told me not to use any metal tools as heat is generated and may cause some problem with the resin, but is ok with any plastic tipe brush or tool. I will try to remove the resin with a floor scrubber but do you think I can use the grinder to stip it and polish it up at the same time to leave my client happy as he should be!!
Please help!!
just throw some 200 grit and go wet. If it comes off smoothly then clean and let it dry. Hit it with the 400 dry and you should have a clearer finish about the same shine as a very well troweled concrete floor. If you want to go higher you can. If it still leaves some cure you could go down to the 100's. If you go lower or slower you will pick up salt and pepper with that husky. If you are worried you can always start at the 400's and work lower to get the cure off. The only issue I've had with this process is the areas around the edges or poorly troweled areas. They will look worse. But the floor overall will look great.
Awesome job Dubbs!! Thanks for the advice! I am waiting on a PG530 and vac as the premises does not have any 3phase power supply!! As soon as I take possesion of it I will start with the prosess. The concrete floor that we initially did looks great and 95% of my clients would of been satisfied with the result, but this client wants the stains to be completely removed. I would try and remove the stains by slightly polishing them out rather my client painting the floor (maintenance). He would struggle in any event to paint a floor with a resin based curing agent installed. Again thanks for the help it is much appreciated!!
If you are asking if you can strip and polish in one step with a resin, the answer is no. However, you can often use a resin tool underneath a grinder, full wet, to remove cure and seals and pretty much any gaurd product that is on the market. We have a lot of customers having great luck using our HTC Fenix Pads in 100 or 200 grit full wet to remove different gaurds and sealers. However, a one step strip/remove and polish is not really a reality. Not that familiar with the exact staining you are referring to with the resin based curing agent, but I imagine when you polish those same stains will still exist.
