The Clear Choice. Protection, not Appearance

Ghostshield Siloxa-Tek 8505 makes absolutely no change to the looks of your garage floor, sidewalk or driveway. It is a penetrating sealer with the addition of a fluorocarbon to aid in the prevention of oil stains or the absorption of other automotive fluids. If you would prefer a permanent product that adds sheen or gloss, consider TrueLock PPC.

The Process

The first step is cleaning the concrete and removing any existing sealers or coatings. Then you need to densify the concrete. You should wait 7 days after densification before proceeding with the GhostShield Siloxa-Tek 8505 Oil Repellent Sealer. You should apply two coats. Wet on wet, typically only waiting 5 minutes between coats in any one area — so you work in smaller sections. Please see the installation instructions. PLEASE VERIFY WHICH PRODUCT YOU HAVE AND IF IT NEEDS TO BE DILUTED. <

What is Ghostshield Siloxa-Tek 8510

Ghostshield Siloxa-Tek 8510 offers all the protection of 8505 in a superior penetrating formula. 300 Sq. Ft. per gallon coverage, this solvent based concrete sealer easily repels oil and water while being easier to install and offering better overall penetration and performance. For best results using a densifier 7 days prior is suggested. We suggest Lithi-Tek 4500 mixed with 3-5 gallons of water. See notes below. VOC 300 g/l. A solvent safe sprayer is suggested. Not all inexpensive sprayers are safe for solvent-based applications. 8510 Flood Coat Modified Floor Coat Application Tip Sheet

Why Is it So Expensive

Unlike traditional penetrating sealers and waterproofers, Ghostshield 8505 is scientifically formulated and proven to withstand automotive chemicals. Typical sealers may afford some short term protection, but if you are worried about constant exposure to oil you would want the 8505. The superior technology and additional ingredients make the product more expensive. Like the saying goes, you get what you pay for.

Where to Use It

Ghostshield 8505 is typically used anywhere you would park a car. Normally that includes driveways and garage floors but there are other applications as well.

Easy on the Densifier

It is very very important that you do not over apply the densifier (or 8505 for that matter). Do not allow it to puddle. Apply only what soaks in immediately. Dilute 4000 before application. For average concrete 3 parts water to one part 4500 densifier. For smooth or polished concrete 4 parts water to 1 part densifier. Over application of densifier or 8505 will cause horrible white area that is tough to remove. Depending upon how much is applied it can usually be removed with a nylon bristled broom, if heavily over applied a floor buffing machine with a scotch pad may be required.
