We are so frustrated that we are considering a different floor material altogether. Owners' and customers' expectations are rightfully high and their level of scrutiny is intense. These different troweling methods make the concrete surface less dense at the edges. On interior concrete slabs, this is usually caused by overfinishing or excess water in the concrete, resulting in a weak surface. Then a penetrating dustproofer and hardener is installed, extending the life of the worn concrete.
Because this type of repair is more visible than crack injection, aesthetics are very important. Then you can apply a stain, tint or dye that penetrates into the concrete. In many areas, the cream is popping off of underlying large aggregate, and in other areas, pieces of the floor are starting to come out, which is causing a hazard for women wearing high heals. Our contractors have tried both a matte and high-gloss finish. The main worries here are if the separation will lead to joint edge deterioration over time especially with seasonal changes impacting on the level of separation or if sanitation is a concern.
Over the long run, this can save you a considerable amount of money and effort over replacing flooring every few years. A model concrete slab contains more water than is needed to activate the cement. Aside from the number of cracks, their severity leads me to believe they are beyond what I would consider acceptable for a floor of this type. Any input you could give us would be great. Did the concrete freeze after placement? Fill the crack with joint repair compound. No expansion joint material was wrapped around these metal boxes before the concrete was poured. I've been told that it is too late to have the concrete polished because of the color application.
The dirt comes right up, but the tracks and scratches from any object that comes in contact with the floor remain. Not all waxes are alike. Finally, seal your work with a good sealer, followed by a finish wax designed for stained concrete floors. Some of the common flaws associated with concrete include: pop-outs, pinholes, gouges, spalling joints and cracks. Having Problems With Your Polished Concrete Floor? Change to diamond resin-based pads to begin polishing. May be influenced and exacerbated by climatic conditions. Venable said that cracks, spalls and other deformities in the concrete must be properly repaired before polishing.
Wait for the adhesive to dry to a point where it no longer appears wet but remains sticky when touched. Repair of minor flaws is easy and can turn a potential safety hazard or unsightly blemish into something barely noticeable. The inherent coldness of concrete can be offset to some extent through the use of carpets and throw rugs. The cracking is probably causing an already weak surface to come off. We usually cover this with a bridging membrane and finish material.
Substantial likelihood of larger spalls and impact damage. Edges are exposed to impacts resulting in greater spalling. I know the wax is a Johnson product, and the floors were not buffed. Does it state that it needs to be burnished? The process involved in repairing a chip in the concrete surface is quite simple. The tape marks are about an inch wide. Unfortunately, the contractor went out of business shortly after project completion, and the general contractor has been less than sympathetic about the problem.
After adopting this process, the repaired polished concrete floor could be ready for traffic again in as little as 30 minutes. The first option involves cleaning out the separation voids by removing loose debris mechanically or with compressed air and then refilling it with a fast-setting semi-rigid polyurea; or slower-setting epoxy joint filler. Since the water was added at the ready-mix plant under controlled conditions, it's more likely that your concrete was overfinished. If either of these includes the issues being faced, then the joint should be addressed. We had to sawcut and remove portions of the floor for new underground mechanicals and then pour these sections back. This is where joints come into play. I always look at control joints as cheap insurance.
Concrete repairs needed to be functional but not necessarily aesthetically pleasing. Concrete floors experience dynamic changes throughout their service life. Wait 30 minutes for the remover to strip away the sealant and then scrape the remover from the concrete surface using a putty knife. High gloss finishes, stained concrete and decorative designs demand a much higher degree of expertise when performing joint and crack repairs. As a general rule, these finishes should not scratch under normal daily use, but they are not immune to wear over time.
About six months ago, the builder removed the sealer and waxed the floor to allow it to breathe and the salts to rise through the floor. These products are applied to the crack or joint with a caulk gun and are available in a wide range of colors. If the subbase is jeopardized or was not prepared properly, no number of control joints will limit the cracking. By utilizing high quality concrete floor repair products and processes, we can guarantee that our repairs will last under the heaviest of industrial conditions. Chips and spalls weaken a floor's structural integrity and worsen over time. The fact that the contractor who installed the concrete is out of business also does not give me a lot of confidence in the quality of the work. We were told we should rewax yearly, but have not been able to remove the scratches or prints since the floor was waxed the first time a month or so ago and then again a few weeks later.
