How long to new concrete have to cure before you can install the product? Will this prevent oil and diesel fuel from staining concrete
Asked by: newshop
New concrete should be cured for at least 28 days before sealing with our Lithi-Tek 4500. If you would like protection from oil based materials, we would recommend treating the surface with our Siloxa-Tek 8505 once your Lithi-Tek 4500 has cured for at least a week.

Can this be painted over and will it fill in shrinkage cracks?

Asked by: capt
While our Lithi-Tek 4500 will not fill cracks like an epoxy will, it will help to protect cracks up to .3 millimeters wide. Once our Lithi-Tek 4500 has been able to cure for a week, you can paint it as you like.

Is 4500 best product for this application? Nearly 100 year old poured basement walls which are dusting -- when I run my hand across the surface, sand-like material falls to floor. A few coating remnants are covering about 20% of wall. I have improved outside gutters and slope around foundation so moisture coming in is limited and want to harden walls before I cover them with foam insulation panels, framing and sheetrock.
Asked by: mplsthomas
Our Lithi-Tek 4500 is a fantastic choice to harden concrete, although needs be applied over a bare concrete surface. Once our Lithi-Tek 4500 has been allowed to cure for a week, we would recommend also treating with our Siloxa-Tek 8500 to help with protection from organic growth.

1 gal. Invisible Penetrating Concrete Sealer Plus Densifier and Hardener is rated 3.0 out of 5 by 2.
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.

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.
