Has anyone ever had problems with an oil-based primer like KILZ being sticky or not drying correctly?
We removed some vinyl tiles and mastic from a basement laundry room floor (concrete) using BEAN-e-doo. After that we washed several times with a degreaser and dried the room with a dehumidifier for a day. It's a dry climate here so the floor felt dry, but there was a grid-patterned dark stain where the tiles had been. We had some KILZ Original Primer leftover from covering pet odors in other rooms, so I decided to prime it with that.
After a more than a week, most of the floor is fine, but there are patches of sticky primer (it feels solid, but sticky like tape), and there are a few small areas where the primer is still a bit soft and tacky.
I just read the KILZ page about Blocking Stains:
Although it may seem counterintuitive, water-based primers are the recommended choice for sealing oil soluble stains.
My guess is that residue from either the mastic, the BEAN-e-doo or both is still embedded in the concrete, and I should've used a water-based primer.
What is the best way to proceed?
- Give the primer more time to dry
- Paint over it with water-based primer
- Strip the floor and start over
It's about 350 square feet, so really don't want to strip it, but I also don't want to create a bigger mess by doing the wrong thing. My hope was to prime it and paint it with something durable.
