Questions and Answers for Ghostshield 1 gal. Invisible Penetrating Concrete Sealer Plus Densifier and Hardener

A:  Thanks for showing an interest in Ghostshield products. Lithi-Tek 4500 is a densifier and will increase the mass of a concrete slab - making it slightly more difficult to drill. However, the most significant changes to the concrete occur near the surface.

A:  Thanks for showing an interest in Ghostshield products. Yes, we recommend letting it dry. However, like most densifiers, the longer you leave them, the better they work. Additionally, there is no one-size-fits-all scenario. Expected dry time can vary depending upon temperature and humidity. Most surfaces should be dry and walkable and ready for next stage of polishing in 1-2 hours.

A:  Thanks for choosing Ghostshield products. Lithi-Tek 4500 creates crystalline structures in the concrete after application. This process can take up to 7 days. We suggest waiting 5-7 days before applying Siloxa-Tek 8505. Be sure surface is clean and dry before applying.

A:  Thanks for showing an interest in Ghostshield. We've never tested our products on Bostik Trucolor. However, we would suggest treating the floor with Lithi-Tek 4500 prior to using the urethane grout. Seal using Siloxa-Tek 8505 after using the grout. We also suggest testing for color / capability in inconspicuous area prior to treating the whole floor.

A:  Thanks for showing an interest in Ghostshield. Stains from fallen leaves are unavoidable no matter which concrete sealer you use. The secret is finding a top coat sealer that makes cleaning those stains simple and easy. For that, we would recommend Cryli-Tek 5500 or 5505.

A:  Thank you for showing an interest in Ghostshield products. - Taken from article via Concrete Network, "When it comes time to applying densifier to concrete that will be acid stained or dyed, the timing differs. With acid stain, it's best to apply densifier after the acid stain has been applied, rinsed off, and neutralized because the densifier creates a more impermeable substrate that could inhibit the penetration and reaction of the stain. Dyes, on the other hand, can be applied after you have densified because they are 100% soluble and penetrate readily." We agree.

A:  Thanks for considering Ghostshield. As with any silicate-based densifier, Lithi-Tek 4500 forms new crystalized concrete particles within the pores of the concrete. These crystals reduce the porosity of concrete and works to strengthen it from within. These crystals can create a white/haze look in concrete that was colored with a dark integral color. If the integral color is dark, we would recommend testing in a small inconspicuous area for suitability. Wait at least 7 days after treatment before making your final decision.
