Here is the recommended process for repairing an interior concrete floor crack:
1. Vacuum dirt and loose debris from the crack.
2. Apply SealGreen Patch Cement as you would grout ceramic tile. For help, watch this video: https://youtu.be/twEDdmZhq8Q
3. Allow the filled crack to dry completely.
4. Choose the closest match from our SealGreen Color Chart. Mix with water according to the bottle instructions, then apply to the crack with a sponge or small brush. Let dry.
5. Once colored, the crack should blend in like a natural vein in the floor.
6. After the repair and color are complete, restore the shine to your floor.
To restore the gloss to the floor:
- I would allow the SealGreen W10 about 8 hours to dry completely. You could walk on it in about 2 to 4 hours but before moving furniture, etc. I would allow 8 hours.
- There should be very little odor with the W10 Some people say they can smell it but I personally can’t. It is not like the solvent-based sealers that will drive you out of the house.
- A gallon of the product will cover 1600 sq ft. The positives of using this product is that it can be used on a regular basis as it does not build up and will never need to be removed like a wax. You can use it to keep the traffic areas of the floor shiny on a weekly or monthly basis.
- For the areas that need repair you should use our Concrete Patch Repair product to fill in the cracks. We use this product because it will take the colored stain (I would recommend #280 Bark Brown based on the color of your floor). You will still be able to see the repair but it will look like a feature of the design
- I would recommend that you use the E10 Epoxy Sealer over the areas that you repair. And then finish with the W10.
