How To Seal Concrete Floors With PVA?

Before brushing your PVA solution on your concrete floor you must make sure it’s free of dust and grit.

We use a hoover and a stiff brush to remove any debris from the concrete floor.

Once you have made sure there is no debris left then grab a soft brush and apply the solution evenly.

You will only need to apply one coat and it should dry within 8 – 10 hours.

Once it dries it becomes waterproof and clear so you will not see the milky white solution.

Another benefit of sealing your concrete floor with PVA is that it soaks deep into the concrete making it waterproof and ready for painting.

  1. Hi if I use the 50/50 pva mix on my garage floor, do I still need to thin the first coat of garage paint as some suggest? Also I was going to use Leyland floor paint.. What’s your recommendation?

  2. I have lots of old paint on my concrete thats near impossible to get off. Can I play over it and repaint?

    • Hey Edward,
      I would suggest you sand away the paint to it’s flush before painting. Seal it again and paint, if you do not sand the previous paint it will stick out once painted again.

      Hope this helps
