Questions & Answers

Can this product be used as a clear coat over Behr Premium Concrete Stain?

Asked by: Jeff
NO. This should be the FIRST thing you put down to harden and reduce porosity on weak concrete or to provide and extra durable surface for polishing a slab. THEN apply the 8505 product as a primer if using a latex or water-based (non-enamel) finish. Or, apply oil or enamel paints, finishes directly over the top of this product without any additional primer.

Can you use a concrete stain or a garage paint on top of this product

Asked by: Sleepy
I don't know why not. All the does is harden the concrete. I just applied it and left it plain to reduce dust from abrasion.

I plan to seal a stamped concrete paver (small 75 sq ft) patio extension with #8505. Is #4500 really necessary for this small area and when is it advisable to use #4500 prior to #8505? If I don't use the #4500 will my project be expected to fail?
Asked by: alh
Hi Al. You can go directly toward sealing with the Siloxa-Tek 8505 as long as the patio has not been previously sealed. Lithi-Tek 4500 is recommended for natural poured concrete, rather than stamped, colored concrete.
