Water Repellents Stain Repellents Graffiti Management Acid Rain Resistance

Water Repellents

Major contributors to the increased rate of disintegration of masonry surfaces:

• Layers of dirt retaining water on exposed surfaces
• Freezing and thawing, acid rain, stains and chemical reactions

Diedrich water repellents stop deterioration and will reduce bonding of airborne dirt and hydrocarbons.

• 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 40�F

Diedrich 303WB Water-Base Siloxane Water Repellent is a VOC compliant, water-based, penetrating, breathable siloxane product

Advantages:

• Specially formulated for use on precast and poured in place concrete, sandstone, clay and concrete brick, and stucco surfaces where surface darkening is unacceptable
• Can be used on both horizontal and vertical applications
• Reduces bonding of airborne dirt and hydrocarbons
• Water damage caused by freeze/thaw cycles is reduced
• Provides protection against efflorescence and exhibits excellent resistance to ultraviolet rays, acid rain and chlorine ion penetration

Limitations:

• Air and surface temperatures must be 40 F or higher at time of application. Re-pointing should be done and allowed to dry before application. Caulking must be done and allowed to cure or until material is set, as per manufacturer=s instructions. Protect surrounding non-masonry surfaces such as glass, aluminum, painted surfaces etc. Any inadvertent drips, splashes or runs should be removed with water before solution has dried on the surface. Application of the product should not occur when rain is expected within 4 hours. Do not allow product to freeze, store at room temperature (65F).

Typical Coverage Rates:

Note: must be applied as packaged and per recommendations, do not alter or dilute the product

• Poured in place & pre-cast concrete: 100-150 sq. ft./gal.
• Hard burnt brick: 125-150 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 20�F 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
