Exposed Aggregate Sealer

The Siloxa-Tek 8510 is our flagship exposed aggregate sealer and a triple threat when it comes to protecting against water, salts and staining. This can include oil and grease that may leak from a vehicle on a driveway or salt water that may splash from a salt water pool. Because of the small amount of solvent carrier, this high actives penetrating sealer is the deepest penetrating and longest lasting sealer in the Siloxa-Tek line.

Available only in a ready to use version, two coats are easily applied wet-on-wet with a solvent rated sprayer, roller or brush.

The 8500 is used to protect exposed aggreagte from water, salts and weathering. This can include deicing salts and salt water that may splash from a salt water pool. If concrete is exposed to salt and left unsealed it can result in spalling, pitting and cracking. The Siloxa-Tek 8500 is able to resist this salt damage and keep concrete strong and waterproof. Not only that but mold, mildew and efflorescence growths are reduced and are easily cleaned off.

Available in a ready to use version, or an ultra concentrated version. The ultra concentrated version is mixed with 4 gallons of distilled water prior to application. Two coats are easily applied wet-on-wet (the second coat is applied immediately after the first coat while the first coat is still wet) with a sprayer, roller or brush. The concrete retains its natural appearance after sealing and will not yellow or fade with UV light exposure.

When you are looking to bring out the colors and textures of exposed aggreagte with a clear, non-yellowing finish the 5505 is an excellent choice. Since the 5505 is solvent based, it is the longest lasting sealer in the Cryli-Tek line. The 5505 can be applied to a substrate that has been previously sealed as long as the previous sealer was a solvent based acrylic. Keep in mind acrylic sealers do not last as long as penetrating sealers and may need to be reapplied more frequently.

One thin, even coat of the 5505 is applied with a 3/8” nap solvent rated high quality roller.

The 5505 may be slippery when wet. The Grip-Tek 250 slip resistant additive can be mixed in to the 5505 for added traction. If the wet look finish of the 5505 is too shiny the Matte-Tek 5000 may be added to reduce the gloss.

We took all the best attributes of the 5505 - clear, non-yellowing, UV stable and made it into a low gloss, water-based formulation. It is not overly glossy or shiny but will keep exposed aggregate protected from weathering while remaining breathable.

The 5500 is water based and VOC compliant in all 50 states making it a great option in areas with strict VOC laws.
