Exposed Aggregate Sealer - Ghostshield Concrete Sealers

EXPOSED AGGREGATE

Exposed aggreagte sealers and coatings

When it comes to choosing an exposed aggregate sealer or coating you must first decide the finish and the level of protection you are looking for. If you are looking for an exposed aggregate sealer to enhance the colors and textures with a wet look or gloss finish you are going to want to use a decorative concrete sealer. If you are looking to keep the appearance of the exposed aggregate in its natural state you are going to want to use a penetrating concrete sealer.

Decorative concrete sealers are used to add a decorative finish and they are usually acrylic or urethane based. They are used to protect concrete stains and concrete dyes bringing out the colors and textures.

Penetrating sealers are used when a natural, flat finish is desired. Penetrating concrete sealers can be water based or solvent based. They are used to protect against salts, including deicing salts and salt water pool decks, and they are able to resist staining from oils and greases.

SILOXA-TEK® 8500

A natural, flat finish exposed aggregate sealer that will not change the look or appearance of any driveway, patio, pool deck or walkway. Water repellency and salt resistance make this our favorite patio sealer.

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.

SILOXA-TEK® 8510

All the benefits of the 8500 with the added benefit of resistance to staining from oils and greases.

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.

CRYLI-TEK® 5505

Best used where a high gloss or wet look finish is desired to enhance and darken the substrate.

VIEW CRYLI-TEK 5505

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.

CRYLI-TEK® 5500

Best used where a satin or low sheen finish is desired. This low VOC, water based sealer will not enhance or darken the substrate but will give it a subtle shine.

We took all the best attributes of the 5505 - clear, non-yellowing, UV stable and made it into a satin finish 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.
