Got a call to fix the floor that is peeling along the expansion joints. I wasn't original installer,but it wasn't installed more than couple years ago. As we started to peel whatever is loose, kinda got obvious that all the moisture that runs inside the joint, pools up and because inside of it wasn't coated at all,that moisture repells the flake with base coat ,only couple inches away from the joints.The rest has good bond. Customer also said he is washing the car there all the time and there's a good slope towards the drain, but whatever water gets in the joints just sits there ,dirt being soaked also inside of it. Would you cover the joints all together or just clean it up, let it dry and coat the inside of the joint, just to seal it? I told him I can blend the patches in as good as I can, he doesn't care if it looks a little different, but my concern is that it doesn't happen again more than esthetics of it.

Looking for some recommendations for your favorite crack filler you’ve used, something strong, doesn’t sag much, 1:1 ratio for less errors mixing, easy to spread doesn’t need to be ground afterwards. Currently using ChemTec Chem Filler. Does a decent enough job but looking to see if there’s better on the market. Thanks!

The first time I accepted the job just over the phone and gave an estimate from the picture, which I knew right away will have have some "flaws" , but it was significantly worse when we showed up and I had to tell the homeowner that we CAN do it, but I can't warranty this because of the condition of the concrete ,which he was OK with and said that he understands everything, due to circumstances, he wasn't pouring new concrete 🤷🏻‍♂️ Once we opened up the cracks and cleaned everything, it made it look 100 times worse 😁 . Have you done jobs like this or would you ?

Hello all, Here’s a conflicting issue , I come from a Flooring background , I started studying epoxy resins around six years ago and with a lot of practice and quite a bit of frustration started and Epoxy Resin business around a year ago . With different products, I always consult the manufacturers technical team. We’ve recently started a project where by I’ve had to lay a levelling compound. It’s fibre reinforced, flexible and has compression strength of 30 N plus , I always apply a DPM primer and I always grind, but when I recently spoke to the manufacturing company, they stated that the DPM would easily adhere to the Levelling compound because it’s cementitious and there is no need to grind …. ! what’s everybody else’s thoughts on this? Thanks and regards, Reece

A lot of times when we see bubbling / product peeling ( like in the pic ) ,first thing comes to mind is bad prep, meaning didn't grind or surface was dusty ? But what are other possible reasons theoretically at least? I'm still battling with my decals, redoing them again and peeled the whole thing off and the product ( base layer ) was stuck to the decal more than to concrete, which made me very skeptical and obviously upset. I know for fact I grinded the surface and there was no dust, because I was prepping specifically for putting decals on and I acetone whiped it before putting the base layer. It was polyaspartic and after couple hours I slapped stickers on, highly doubt that sticker glue could have effected it, or could it? I won't be able to sleep at night now 😬 I cut the outlines of the stickers, so it didn't peel anything else and there's only gonna be foot traffic in there, but overall situation is not good. Any thoughts?
