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 this product be applied over texture painted concrete (RUST-OLEUM Deck & Concrete Restore)? I have two small but long cracks across the concrete slab. Rain water works its way into the basement through them.

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.

surface cleaning or prep of two month old garage floor,prior to applying 4500? thanks
Asked by: steve
You will want to strip and etch (acid) before applying. HOWEVER, if you don't have reason to believe your slab is weak/soft and you're not polishing it you really don't need to apply a hardener/densifier like this. I would simply go with a clear or other concrete sealant, or epoxy garage paint that is rated for new slabs. Save yourself A TON of heartache and work.

1 gal. Invisible Penetrating Concrete Sealer Plus Densifier and Hardener is rated 4.0 out of 5 by 7.
Rated 4 out of 5 by from Use with 9500 I wanted to get the absolute best results so I contacted Ghostshield and told them my situation. They recommended 4500 followed by the 8500 for my badly worn 98 year old concrete. I had already purchased the 9500 and had it laying around and they said it would work as a substitute for the 8500. After cleaning, acid etching, and neutralizing and letting the concrete dry I applied the 4500. Apply it thinly or it may show white residue. The residue can be scrubbed off. I let the 4500 cure for 7 days then I applied the 9500--2 coats. I had significant efflorescence, dusting, etc prior to sealing with this two coat process. I can tell you the efflorescence has been reduced significantly and water beads right off. Hope this helps someone trying to find their way in the crowded world of concrete sealers.

Easy to roll on. be sure to clean the surface on all concrete dust or you will have white patches of concrete on you finished work(I have not been able to remove this on tested location). I guess it will make the concrete as hard. I used a hard bristle bursh and a blower and got great results.

Rated 2 out of 5 by from Sealer? I don't think so. Followed the instructions to the letter, put this on my driveway, walkway, and front porch and then nothing. There is no difference in my drive before the application. Waste of time, waste of money. Skip this step and just go right for the sealer.

I used this product as a primer before using the Siloxatek 8505 in my garage. After six months and a winter season they have held up great. I will say make sure you apply one coat very even since in the beginning we went a little heavy and it left some white spots. They easily came off by sweeping and then we were safe to apply the topcoat.
