Strengthen. Seal. Protect.
EnviroSeal is a ready-to-use, penetrating concrete sealer formulated to deliver long-term protection by converting water-soluble minerals into insoluble compounds. This reaction reduces porosity and permeability, while increasing chemical resistance, hardness, and durability of concrete and masonry surfaces.
Key Benefits:
- Permanently seals capillaries in concrete and cementitious substrates
- Prevents efflorescence and improves chemical resistance
- Strengthens concrete to extend service life
- Will not peel, scratch, or wear away like surface sealers
- Compatible with polishing for a glossy, high-sheen finish
- Environmentally friendly, inorganic, and water-soluble formulation
Ideal For:
- New or existing concrete, mortar, stucco, plaster, and porous limestone
- Foundation walls, retaining walls, driveways, sidewalks, patios, pool decks, and slabs
- Interior and exterior applications
Limitations:
Not intended to seal cracks, joints, or gaps
Not suitable for:
- Concrete less than 3 inches thick
- Fiber-reinforced or lightweight/low-cement-content concrete (e.g., split-face, popcorn, or dry-pressed blocks)
- Surfaces with integral colorants, patching compounds, or leveling additives
Why EnviroSeal?
Unlike membrane-forming sealers that wear away in high-traffic areas, EnviroSeal penetrates deep into the substrate, delivering long-term protection without compromising aesthetics. Safe, sustainable, and high-performing EnviroSeal is the smart choice for lasting concrete care.
EnviroSeal CONCRETE DENSIFIER
EnviroSeal is a cost-effective concrete sealant, but like cement itself, it yields the best results to those who thoroughly understand how it works.
When dry cement is mixed with water, the cement particles begin to dissolve and react to form a calcium silicate hydrate (C-S-H). The volume of C-S-H is greater than the original unhydrated cement particles, so as C-S-H forms it fills in porosity, providing strength and rigidity to the cement. Another by-product of cement hydration is calcium hydroxide (Ca(OH)2). The presence of Ca(OH)2 adversely affects the properties of cement because it is attacked by acids and other chemicals. It also tends to crystallize as hexagonal platelets near the paste/aggregate interface, resulting in a poorly packed (i.e., low density) weak area. Applying EnviroSeal, however, reduces the amount of Ca(OH)2 near the surface because EnviroSeal reacts with Ca(OH)2 to form C-S-H (see chemical equation below). As a result, the surface is less permeable, more resistant to chemical attack, and overall more durable.
Ca(OH)2 + sodium silicate = C-S-H + free Na or NaOH
The C-S-H gel formed from this reaction is insoluble in water and more resistant to acid and other chemical attack.
All concrete is porous, although the type and amount of porosity can vary greatly from one concrete to the next. These differences occur because of the water-to-cement ratio, amount of working, quantity and type of aggregate, temperature and various other factors. Depending on its quality, method of placement and curing, a standard concrete can contain a significant percentage of Ca(OH)2 which also contributes to porosity when it dissolves. Therefore, it is essential to convert the Ca(OH)2 to C-S-H in order to increase the life of the concrete.
