What Is PVA?
PVA or (polyvinyl acetate) is well-known wood glue that has many names such as white glue, chippy glue, school glue and bulders glue! It has many names and is suitable for many jobs.
When you apply PVA it’s white, but when it sets or dries it becomes translucent (clear). It is the most used glue for DIY purposes and will always be.
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 your concrete making it stronger, waterproof and ready for painting.

There are many versions of this PVA mix, but we keep it simple because we know it works. Grab your self a bucket, add 2 litres of water and 2 litres of PVA, give it a good mix and you’re ready to go.
- Half PVA and half water

Conclusion
PVA is a great solution, there are many brands of concrete floor sealers available in the UK. But PVA has always been our first option because it’s perfect for concrete.
Many discussions have been surrounded by this formula but the arguments are from companies selling their sealers and DIY enthusiasts with not much experience in DIY.
All we know it works and works extremely well, we advise our readers to take advantage of this solution and enjoy a waterproof and sealed concrete floor for many years to come.
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?
Hey Peter,
No, because you have sealed the floor with a PVA 50/50 mix you can apply any floor paint neat from the tin. The watered-down paint solution is a bad way to seal your concrete floors!

Hope this helps
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
