Ghostshield 9500 over Cure and Seal 1315

[ManOnTheCouch]

I’m building a new house and detached garage. When the builder/concrete contractor poured the basement floors and slab for the detached garage, they used a 1315 cure and seal.

Any issues with going over that with Ghostshield 9500?

Thanks

I'm sure the experts will weigh in but cure and seal products form a barrier on the surface of the concrete to seal in moisture for curing and seal out stains. Even if they are advertised as dissipating, they still block penetrating sealers that are usually applied after the concrete has fully cured in 28 days. I suspect you'll have to remove the 1315 for the Ghostshield to work.

Well said.

@OP First, unless you are in an area that does not have snow or freezing temperatures and no road salts 9500 is a waste of money. It also does little for stain resistance and does not repel oil. A true densifier would be a better choice and 8510 over a densifier would be the best choice for a sealer.

Prior to doing anything the cure n seal needs to be removed. The issue becomes sealers don't fill, they penetrate.... You do not want to create any additional surface texture while removing.
