How To Repair Stained Concrete

Question:

I recently patched some pocket-size cracks in a concrete floor and at present I want to stain the entire floor. Volition the repaired areas absorb the stain like the residue of the flooring? I desire the colour to be uniform.

Answer:

Any time you stain a floor with repaired or patched areas, await a color difference. The base colour and graphic symbol of the concrete has a lot of influence on the last color and look that is accomplished when you utilize translucent stains or dyes. Since a concrete patching material will take a different porosity and contour than the existing concrete, information technology tin exist expected that the repaired areas will stain differently. Sometimes the differences will be subtle, and sometimes they tin exist extreme. Always do a test to determine the actual color difference that might occur. If the color difference is unacceptable, consider applying a concrete overlay or microtopping over the unabridged slab to achieve a new, uniform surface on which to apply your stain.

Question:

I saw your Concrete Network articles and those of others about acrid-stained concrete floors. Only I did not come across whatever articles on retouching stained concrete floors. The reason I'm contacting you is that I have a 2x2-pes hole in the middle of my beautiful stained and scored concrete living room floor caused by jack hammering to repair a water leak under the foundation. Any suggestions you could give me regarding how to go about repairing and restoring the floor to its original status, and on a $two,270 budget, would be appreciated.

Can the hole be filled in with concrete and bull floated evenly, and then rescored with a new diamond bract at the appropriate depth? Tin can the 2x2-foot balderdash-floated area exist retouched to match the original brownish-red stain colour, and if so, can you recommend what acrid stains to employ? Or will we take to employ an overlay on the entire living room floor to get a reasonable friction match?

This is one of the more interesting issues I take come up across in 10 years. What a tough break and situation. Trying to patch a stained floor is truly one of the hardest rehab jobs out there. You demand to match the texture and finish of the concrete, and and then match the color and tone of the stain. Whatsoever patch textile - concrete or polymer - will stain differently, then it will be virtually impossible to get a practiced texture and color match with any type of patch. These are the options I suggest:

• Cut the pigsty to the closest sawcut lines to create a neat and uniform opening. This way you will be working inside a designated space and won't take to worry near blending outside the lines. Make full the hole with concrete, then come up back with a white or calorie-free-colored microtopping skim glaze to match the profile and texture of the residuum of the floor. Become a professional to work with the stains to match the original color.
• Fill the hole with physical, then grind down the entire floor and cover it with a microtopping (come across Decorative Concrete Overlays). Adjacent, restain and seal the entire flooring.
• Since money is an event, endeavour your best with a patch and use a throw rug to cover the area. Not the best solution, merely I have seen information technology done successfully. Or you lot could even create a "faux" throw carpet by stenciling a design over the patch and turning it from an eyesore into a decorative focal indicate. (See Stenciling Concrete Interior Floors.)

So, basically the options are to try and match a patched hole to the balance of the floor or redo the unabridged flooring. I am not sure either remedy will work inside your upkeep. The patch method also runs the risk of creating a spot on the flooring that looks so different, it attracts attention and becomes a bigger eyesore.
