ULTRA MASONRY BLOCK SEALER is a non-toxic, non-caustic, non-flammable formulation with no equal. It permanently waterproofs and preserves with one easy application. (Normally with one coat at 200 sq. ft. per gallon) is approximately 4.9 square metre/litre

MASONRY- A LIFETIME BOND All foreign chemicals are cancerous to concrete and masonry.

Foreign chemicals is any acid, alkali or oil found in the masonry or spilled on it (Such as lactic acid in milk, oil, alkali, chemicals, etc.) These cancerous substances embed themselves in the masonry.

Benefits of Ultra Masonry Block Sealer

  1. Ultra Masonry Block Sealer when applied to the masonry, concrete, plaster and stucco will penetrate and bind all component parts of the masonry into a more dense or solid mass.
  2. As the masonry increases in density, it becomes waterproof and resistant to acid, oil and grease.
  3. Ultra Masonry Block Sealer stops dusting, rutting & spalling. This process will stop cracking, crumbling, seepage and pitting while increasing the density of the masonry.
  4.  Ultra Masonry Block Sealer also increases the tensile strength of the concrete as it fills all the voids preventing any penetration of water or contaminants from the surface either horizontally or vertically. Anything applied only to the surface of the masonry must eventually come off due to aeration and deterioration.
  5. Can not deteriorate or wear off. Masonry Block Sealer soaks into the surface. Instead, it cures, waterproofs and seals the masonry permanently.
  6. Abrasion resistant


Because Ultra Masonry Block Sealer seals the concrete so well, non-moisture resistant paints such as latex may not bond well.
Only a good quality acrylic or oil based paint should be used over an ULTRA Masonry Block Sealer treated surface.
After treating the masonry with ULTRA MASONRY Block SEALER, no foreign substance can penetrate into the masonry and will stay on the surface where it can be washed off easily.

All masonry treated with ULTRA MASONRY Block SEALER will stop disintegrating. You will no longer be able to remove a portion of the concrete, brick, stucco etc. surface by running your finger across the surface based on the fact that component parts of the masonry are solidified into one mass, rather than a billion independent particles.

Untreated Concrete     |       Treated with Ultra MBS    


For industrial, commercial and residential use on concrete, brick, stucco and all masonry. For homes, warehouses, commercial buildings, factories, roads, tunnels, bridge decks, parking lot structures, driveways, concrete roofs, subways and basements.
Seals inside or outside on new or old masonry.
Authorized by USDA for use in federally inspected meat packing plants and poultry houses.


All surface cleaning materials should be pressure washed off to remove completely.

Apply in good weather when air and surface temperature are above 5 °C.
The temperature must remain above 5°C. for 24 hours after application. For optimum application properties, materials should be between 5-35 °C prior to application.
Maintain unmixed material in closed containers in protected storage at 5-35 °C.


Latex paints form a very weak bond. It is NOT recommended that latex paint be applied over ULTRA MASONRY BLOCK SEALER, especially on horizontal surfaces.
Use only a good quality moisture resistant acrylic or oil-based paint over an Ultra treated area.


Good surface preparation is essential to a satisfactory coating. Surfaces to be coated should be clean and dry. Remove all dirt, dust, oil, grease, mildew, rust and loose or cracked paint or other contamination by first cleaning the surface with CONCRETE CLEANER rinse thoroughly and allow to dry.


  1. Pressure wash the surface to make sure that it is clean and all cleaning materials are completely removed.
  2. Apply Ultra over block, brick, concrete or any type of masonry surface using a low pressure sprayer (Hudson type) or any spray at no more than 20 psi.
    Consumption: approx. 1 lit to 4-5m2. area.
    Allow to dry.
  3. Allow 5-7 days for completion of the curing process and penetration after application. Prior to painting walls or slabs, wait 24-36 hours.
    Use only a good quality moisture-resistant acrylic or oil-based paint over an ULTRA treated area.

See MSDS Sheet for application over existing paint. Wash all tools and equipment with soap and water as soon as possible.
Any spills may be cleaned with soap and water before it dries.
