Acid Rain Resistance

303-S Siloxseal Siloxane Water Repellent is formulated to protect against the intrusion of moisture that causes efflorescence, leaching, mildew, atmospheric staining and freeze/thaw cycles.

Advantages:

Effectively resists the effects of acid rain and carbon buildups
Ideal for concrete flatwork, parking ramps, stadiums and vertical concrete surfaces
Reduces migration of sodium chloride ions through cement thereby reducing corrosion of rebars in reinforced concrete
Formulated for low-pressure spray application

Limitations:

May not be suitable for some types of natural stone, limestone & marble
Not suitable for surfaces to receive paints or coatings
Must be applied above 40ºF

Typical Coverage Rates:

Note: This product should not be diluted

Salt-Bloc Chloride Barrier: is an all-purpose, deeply penetrating siloxane water repellent and chloride barrier for concrete and pavers.

Advantages:

Blocks absorption if chloride ions from de-icing salts into concrete, brick, and concrete paver sidewalks and driveways
Protects against efflorescence, leaching, mildew, atmospheric staining, chloride salts and freeze/thaw cycles.
Ideal for horizontal surfaces, retaining walls, bridge pilings and other vertical concrete applications
Highly effective in coastal areas by protecting surfaces from airborne salts

Limitations:

May not be suitable for some surfaces - gypsum plaster, synthetic resin paints and other non-masonry surfaces.
It is not recommended to paint over surfaces treated with Salt-Bloc
Do not use on surfaces subject to constant water spray (i.e., car washes, water fountains)

Typical Coverage Rates:

Clay/Brick Pavers: 100-150 sq. ft/gal
Cement Brick Pavers: 100-150 sq. ft/gal
Pre-cast & Steel Troweled Smooth Concrete: 125-175 sq. ft/gal
Exposed Aggregate Smooth Concrete: 100-150 sq. ft/gal

333 Omegaseal Water Repellent: is a split face block sealer with heavy-duty solids and provides hydrophobic protection to masonry surfaces through the formation of a semi-permeable membrane.

Advantages:

The flexible membrane remains intact through thermal movement of masonry, rejects water in the solid state and allows for moisture vapor transmission - it breathes.
Can be applied year round at 20ºF and above
A unique blend of silicone polymers provides maximum resistance to ultra-violet light and acid rain
Functions very well for graffiti protection

Limitations:

Can not be applied to wet, damp or dirty surfaces
Not suitable for any polished masonry surface
