BEHR advertises their Premium Protector and Waterproofer product as a silicone waterproofer to penetrate and keep water out while shielding against corrosion and salt damage. The Behr premium interior and exterior waterproofer claims to protect concrete for 10 years. It uses water based silicone technology designed to penetrate surfaces up to 1/2 inch. The waterproofer creates a barrier inside the surface that keeps water out but lets water vapors escape reducing corrosion, spalling, efflorescence and freeze-thaw damage. The protector and waterproofer can be used on horizontal and vertical uncoated concrete and masonry surfaces such as concrete block, pavers, stucco, brick, unglazed tiles, exposed aggregate, concrete, sandstone and slate. Before you apply Behr premium protector and waterproofer it is essential you have a properly cleaned surface. Apply until saturated by brush roller or garden sprayer to a dry surface.
The Siloxa-Tek 8500 manufactured by Kretetek Industries is an excellent example of a concrete sealer. The Siloxa-Tek solution is a special one that promises waterproofing protection. While many sealers offer this level of protection, which is such a huge benefit for people looking to protect their concrete, the Siloxa-Tek is of a different chemical make-up; it is, therefore, much better suited to locking out water.
The Siloxa-Tek is a silane/siloxane solution, which both penetrates within the concrete as well as giving it a level of surface protection. Because of this, water is locked out in two steps: from within and from without. The water will actually bead on the surface of concrete treated properly with the Siloxa-Tek 8500, so you can see the sealer in action. The sealer is water-based and VOC free, offering such benefits as preventing efflorescence and resisting stains, as would be expected of any high-quality sealer.
The Siloxa-Tek 8500, a DOT approved, water repellent impregnating sealer changes the surface tension of mineral substrates to produce a water repellent surface to keep water and aggressive water-soluble salts, such as chlorides and sulfates, out. Also the 8500 provides excellent resistance to freeze-thaw cycles, spalling, cracking and pitting. While the Siloxa-Tek 8500 is not suitable for every single concrete sealing project (such as for decorative concrete on a pool deck, for instance), it is one of the best choices for many of them especially driveways, sidewalks, roads and bridges. Readily available at HomeDepot.com this sealer is an excellent choice for most projects.
DryLok has been around for many years with their traditional DryLok formula claiming waterproofing, yet never living up to the hype causing consumers trouble. Finally DryLok is out with a new patent pending formula. DryLok Clear Masonry Waterproofer. How does it perform and does it cause the same amount of headaches that DryLok the original latex based ‘waterproofer’ does?
DryLok’s website description states, “DryLok Clear Masonry Waterproofer is the first non-pigmented masonry waterproofer specifically formulated for use on bare masonry floor and wall surfaces. This technology provides a durable, waterproof, easy to clean, non-yellowing high gloss finish. DryLok Clear Masonry Waterproofer incorporates environmentally safe green biocides, to resist the growth of mildew on the dry paint film. DryLok Clear Masonry Waterproofer has been tested in accordance to requirements of ASTM D- 7088 Resistance to Hydrostatic Pressure at 4 P.S.I. and ASTM D-6904 Resistance to Wind Driven Rain of 98 mph.”
Claiming to stop hydrostatic pressure and wind driven rain while leaving a high gloss finish this acrylic latex based formula is still not the solution for concrete waterproofing problems. You would have thought with all of the knowledge out there about latex and water they would have come up with a different composition for their new product.
The Concrete Sealer X-2 product manufactured and distributed by Stone Technologies is a high quality concrete sealer. It is a water-based sodium silicate sealer that features a low volatile organic content that is compliant with most strict state regulations (though be sure to check the requirements for your particular state before purchasing any product). The Concrete Sealer X-2 is an environmentally friendly and well reviewed product that offers a solid level of protection.
The only problem with the Concrete Sealer X-2 comes with its marketing on the website. On the site, the Concrete Sealer X-2 is purported to be an excellent concrete sealer for those looking to seal exceptionally porous materials like brick and concrete block. However, sodium silicates are penetrating sealers that do not work on extremely porous materials. Their small particles are meant to penetrate the equally small surface pores on traditional slabs of concrete. If a sodium silicate sealer were to be applied to a porous concrete, as is advised on the website, the solution would simply leak right through the concrete without chemically reacting (which is where the sodium silicate features most of its strength and protection).
The Concrete Sealer X-2 is a great concrete sealing product for any projects requiring a strong penetrating solution; however, it is not the best choice for more porous concrete.
The Eagle Seal Satin Seal concrete sealer is a non-yellowing acrylic sealer that offers to provide an appropriate level of protection for all types of concrete. However, the Satin Seal is only an acrylic sealer, according to information found on its SDS sheets. Therefore, it is not an appropriate choice for any and every type of concrete; rather, it is appropriate for certain projects that require a surface-level sealer.
The Satin Seal will bond to the concrete’s surface, featuring large particles of acrylic sealant that will not penetrate past the tiny surface pores natural to all concrete. While a penetrating sealer will, of course, penetrate to chemically react within the concrete to provide protection, a surface-level sealer, like the Satin Seal, remains on the surface of the concrete to function like a raincoat; It will repel up to a certain level of water and salts. We would recommend the Satin Seal for delicate types of decorative concrete, stamped concrete and pavers.
If you are looking for a decorative sealer with a satin sheen it would be best to use this product. Just remember that decorative sealers need to be reapplied every year or so, more frequent than penetrating sealers which can last upwards of 5 years.
