Best Concrete Sealers
Concrete sealers play a major role in strengthening and protecting concrete works. A number of concrete sealants are now available, including gum resins, linseed oil, silicon derivatives and film formers such as acrylics, urethanes and epoxies.
Film-former sealants containing solvent-based acrylics are the best choice for sealing surfaces in the case of outdoor applications, as these allow easy escape of moisture. If working with heavyweight concrete blocks, urethanes and epoxies are the most suitable.
Epoxy sealers are ideal for industrial environments, concrete countertops, and food preparation areas since it can form a thicker and tougher film for chemical resistance. Significant types of epoxies are epoxy penetrating sealers and water-based epoxy sealants, which are used in marine applications. For maintaining concrete durability in highways, epoxy-based sealers coated with steel are used. In order to provide an abrasive-resistant finish to commercial areas, urethane sealers are the best. Urethanes can last five to eight years and epoxies up to 15 years.
Concrete penetrating sealants such as silane, siloxane, and siliconate are the most excellent alternatives to treat concrete structures and parking garages affected by deterioration and acid rain. The main advantage of penetrating sealants is that they penetrate into the capillaries of the concrete surface and safeguard the concrete from stains, abrasions, and other harmful factors.
Best concrete sealers must be environmentally safe. They should also have the ability to form an impenetrable barrier to protect concrete surfaces from bacteria, fungus, and corrosive materials such as acids and salts. Further, these should not alter the surface appearance of concrete surfaces. The durability of a sealer depends on the wear and tear of the surface, the maintenance schedule, and the use of appropriate chemicals. It is best to avoid harsh chemicals and cleaners.
In the US, there are a number of local hardware and online stores to provide the latest as well as the best in concrete sealers.

| Product | Description | Uses | Get Data sheet |
|---|---|---|---|
| BARACADE M.E | an oligomeric alkyl alkoxy siloxane concentrate. | When diluted with water, BARACADE M.E. self-emulsifies into a unique product capable of repelling water on concrete or masonry surfaces. BARACADE M.E. is a breathable, non-staining, colorless material which penetrates deep into the surface to seal out moisture, reduce efflorescence and minimize the damaging effects of freeze-thaw cycles. BARACADE M.E. protects without altering the appearance or texture of the treated surface and improves resistance to airborne dirt, smog and other air pollutants. | |
| BARACADE SILANE 100 C | a breathable, ready-to-use, colorless, non-yellowing, deep penetrating concrete and masonry water repellent | BARACADE SILANE 100 C is a 100% silane formulation that produces a hydrophobic treatment to reduce water absorption. BARACADE SILANE 100 C protects concrete, block, stone and brick against the damaging effects of water intrusion, deicing chemicals, freeze-thaw exposure and airborne contaminants such as acid rain, smog and industrial fumes. Due to the 100% silane composition, BARACADE SILANE 100 C exhibits low volatility and higher coverage rates than solvent based silane materials. | |
| CHEMSTOP WB | water-based, ready to use, siloxane/silane water repellent. | CHEMSTOP WB REGULAR is formulated for use on dense surfaces, such as pre-cast or poured-in-place concrete. CHEMSTOP WB HEAVY DUTY is used on porous surfaces such as light weight concrete, concrete block and mortar joints. | |
| EUCO DIAMOND HARD | a unique blend of silicate and siliconate polymers that penetrate concrete surfaces and chemically react to provide an increase in surface density, durability, and abrasion resistance | Concrete treated with EUCO DIAMOND HARD is dust-proofed, resists tire marks, and is easier to maintain. Over time, EUCO DIAMOND HARD provides an attractive, slip resistant sheen to concrete that never peels, fades, or wears away. | |
| EUCO-GUARD 100 | a deep penetrating siloxane sealer designed to protect concrete structures, decks, pavements and surfaces against the adverse effects of de-icing salts, moisture, weathering and freeze damage. | EUCO-GUARD 100 reacts chemically with the concrete to provide a highly effective chloride screen and water barrier. In addition to its ease of application, EUCO-GUARD 100 has the added versatility to be used on both new and old concrete surfaces. | |
| EUCOSIL | water-based sodium silicate solution used to densify and dustproof concrete | EUCOSIL chemically reacts within concrete and becomes an integral part of the surface, making treated concrete denser and easier to maintain. | |
| SURFHARD | water-based magnesium fluorosilicate solution that reacts chemically with alkaline materials in concrete producing a more dense, durable, and chemically resistant floor. | SURFHARD is especially effective at strengthening weak, soft, or dusting concrete surfaces. A patented penetrating agent in SURFHARD assists in its penetration and reactivity, enabling SURFHARD to dustproof and densify at a greater depth. | |
| ULTRAGUARD | water-based polymeric protectant that improves the appearance and durability of concrete floors | ULTRAGUARD contains a powerful stain-resistant additive and is further enhanced with lithium silicate, which provides densification of the concrete surface. This product also contains UV absorbers that enable the ULTRAGUARD to protect coloured or dyed concrete against UV degradation. ULTRAGUARD can be used alone or in combination with a reactive sealer such as EUCO DIAMOND HARD or ULTRASIL Li+ to give concrete floors a glossy finish, harder surface, and protective seal. | |
| WEATHER-GUARD | siloxane penetrating sealer designed specifically for the treatment of masonry materials and concrete surfaces | WEATHER-GUARD protects concrete and masonry surfaces from the effects of exterior exposure and weathering. WEATHER-GUARD penetrates deep into the surface pores and reacts chemically to provide a durable, long lasting barrier against water and salt intrusion. This level of protection can substantially reduce the damaging effects of freeze/thaw cycling, precipitation, acid rain, efflorescence, and dust/dirt degradation |
