Garage Floor Repair With Quickrete Polyurethane Concrete Crack Sealant

We were asked a while ago by the nice folks at Quickrete if we wanted to try a new product they were bringing to the market called Quickrete Polyurethane Concrete Crack Sealant.

That certainly is a long name for this new product.

Its product label indicate it ‘permanently seals & water proofs’, is ‘textured’ and provides a ‘superior bond & flexibility’.

As I had both cracks in my 24 year old concrete garage floor as well as separation between the floor and the concrete foundation, this sounded like a perfect product to use.

Separation Between Concrete Garage Floor and House Concrete Foundation

Here is the first situation. Look at the space all along the edge of concrete garage floor where it is supposed to meet the poured concrete vertical foundation of the adjoining house.

My initial use of this new product saw me treat it as I would any silicone caulking tube. That was as I came to learn a mistake. I simply cut the tip of the tube and then used the small tool underneath the caulking gun (as you can see in the picture below) to puncture the membrane inside the plastic tip at the top of the tube itself.

I then attempted to apply this new concrete crack sealant product into the gap between the concrete floor and the foundation wall. Oh my poor hands. It was really tough to come out of the tube. Because of this, my hand did not have the strength to force a sufficient quantity into this gap as shown in the picture below.

As I came to learn from both personal experience and in speaking with Dan Moy, QA Process Engineer for Quickrete in Atlanta, because this product is much thicker than interior silicone sealant, you need to make a lot of holes in the membrane inside the plastic tip.

Three days later (the product label says to allow ’72 hours before painting or exposing to traffic’) I opened another tube of the Quickrete Polyurethane Concrete Crack Sealant, made sure to puncture a lot of holes in the membrane at the base of the plastic tube. What a difference. The polyurethane sealant flowed out very nicely.

So, I placed a second layer over the initial polyurethane sealant and used the tool above to smooth out the edge.

Once I used the plastic edging tool, the finish was quite nice as you can see above.

I then used this new product to seal several cracks in our concrete garage floor.  Here is a ‘before’ picture of the cracks.

First I applied the polyurethane sealant to a portion (say around 6 to 7 foot length) of one crack at a time.

I then used a common drywall scraper to flatten the excess sealant and ensure it fully covered the cracks.

The entire process only took about 1 hour.

And, I used the GREAT STUFF Work Wipes to clean the tip of the sealant tube, the drywall scraper and even my hands where I found a spot of the sealant.

I then waited 12 hours before I closed the garage door. By that time the sealant was sufficient dried. While the sealant tube labeling states a full cure in 5 to 8 days, it also says ‘Tack free in 2 hours at 75 F with 50% relative humidity’.

I like this product. It should help stop the deterioration of my garage floor by containing the cracks, preventing water from further deteriorating the cement floor, etc.

Thank you Quickrete for providing the products!

    I have tried 2 tubes of this product and purchased them at two different hardware stores. I followed the instructions from on-line and on the canister.I pierced the seal larger than indicated on the tube. It was very granular and thick. The first tube was very difficult to apply with regular gun and did not penetrate 1/8″ cracks in concrete garage floor and resulted in poor adhesion. The second tube was so thick, the trigger on the gun let go before the product got up halfway into the applicator tube. This product has either viscosity or distribution problems.
    I have since tried another higher priced product with lower viscosity and it worked great.
