Is It Necessary To Acid Wash My Bedroom Concrete Floor Before Painting It?

Nano Tech wood and concrete sealer


I have a concrete bedroom floor with some old paint on it and carpet glue.  Is it necessary to acid wash this or is their a simpler solution?  Please advise.  Thank you!

People often paint concrete floors!  I will lay out the process here.
Professionally coating concrete is very different than what is typically done at a diy level.
If I had a bedroom floor that I wanted done fast, safe and affordably, from a diy perspective, I would:
1. Earth Clean
2. Clear Skies Eggshell (any color)
3. NanoTech Clear 00 x 2 coats rolled
That provides a beautiful, easy to clean surface that is very durable. Whenever painting concrete you want to make sure that the concrete is very, very clean.
There is a micro fine dust that forms on concrete. Watch for that. If full prep is skipped, then it’s important to know that the concrete must be washed very well. Remove glue if possible.
The better the prep the better it will last. These recommendations are particularly important for high traffic floors and commercial floors. If the floor was raw and was prepped a bit better you could use a clear sealer like Bio Poly Natural. But since the prep is going to be limited I would stick with the Clear Skies and NanoTech clear coat.
I did this on my dog room floor…actually…come to think of it, my whole basement is painted like that. The water heater leaked (badly) but we only had to touch up one small area right under it; other than that the floor looks great. It had some odor that was sealed in as well.
Sample pints are a great way to test it out and see how the paint will look on your concrete floor.
Hope this helps.
