Black Jack Neoprene SuperflashHigh Performance Elastmeric Flashing Cement

Black Jack Neoprene Superflash
High Performance Elastmeric Flashing Cement

Neoprene flashing cement is a unique professional elastomeric flashing and repair product that cures to a long lasting rubber membrane. This product remains flexible through extreme temperature ranges.

It’s non-sag properties and it’s exceptional adhesion guarantees that Super-Flash is the ideal cement for sealing cracks, holes, and tears in built-up roofs (asphalt and tar) and modified bitumen single plys.

Super-Flash may also be used as a topical repair for EPDM rubber sheets.

It’s advantages include:

  • Remaining flexible and watertight for up to 20 years.

  • It is up to 50 times stronger that plastic roof cement

  • Elongation reaches 250%

  • It is elastomeric

Acousti coat Textured Acoustical spray coating

Florok Acousti-coat is a heavy bodied rubber based coating, in which is suspended millions of “punkey” sand like particles.

It’s pleasing heavy texture, provides a rough matty coating capable of absorbing sound. It cushions and diffuses harsh noise and “bounce back” similar to conventional acoustical tile.

Acousti-coat was originally desgined for concrete ceiling which is often rough, pourus and contoured. It will seal and hide fine cracks, voids, blemishes and discolorations.

Acousti-coat may be sprayed on almost every type of ceiling surface, such as;

    • Prestressed concrete plank or builing members.
    • Plaster or sheet rock
    • Wood or accoustical tile
    • Metal Ceiling Decks

Acousti-coat has been used on many fine churches, restaurants, office buildings, gynasiums, class rooms, apartments, motels, swimming pool ceilings, etc.

Crystal Stain Acrylic Masonry Stain

Crystal Stain is a translucent sealer containing acrylic copolymers of indentical nature to Crystal Clear; however, in addition it contains non-fading, inorganic oxide pigments, and ultrviolet stable colorants of sufficient strength and quantity to uniform concrete, masonry and brick color variations.

Crystal Stain will provide long lasting architectual color toning effect to concrete and masonry without giving the surface a painted look, or changing it’s texture or natural beauty.

Crystal Stain is designed to penetrate into the substrate. The acrylic resins chemically and physically lock into the masonry or concrete surface to become part of it, to form an exceptionally durable and effective moisture barrier to help prevent exterior dampness form entering the interior.

Crystal Stain will hide stains and discoloration caused by efflorescence and other natural defects and imperfections found in most concrete and masonry surfaces.

wet or excessively damp areas.

It advantages include:


    • Excellent adhesion to concrete, metal, cement plaster stucco, cement based paint such as Thoroseal or Quickseal.
      Also, fiber glass and certain plastic surfaces.


    • Easy application by brush, roller or spray.


    • Bright colors that maintain their beautiful lustre for years.


    • Chemically resistant to alkali, strong cleaning and purifying agents required to maintain pool cleanliness.


    • Stain resistant. Dirt and scum scrub off easily.


    • Will not support growth of algae, mildew or mold.


    • No special primer needed. Merely thin first coat with SOX solvent. Apply second coat full strength.

Non Metallic Grouting Compound

Florok non-metallic grout standard grade and High Fluidity grade are complex compounds composed fo selected silica sand conforming to Federal Specification SS-A-281, Portland Cement, hydraulic cement, pozzualonic plasticizing, water reducing, and shrinkage compensation agents.

When mixed with water they develop a positive expansion factor right from the time of placement, with no intermediate or final
shrinkage occurring. Expansion is mass expansion, and final volume filled is not effected by restraining, as with gas evolution or gas liberation type grouting materials, which eventually shrink during final set.

Florok non-metallic grout is applied by trowel or dry pack method. To be used for general grouting or repairs, wherever a very high early and final strength is required and where non shrink or non staining is an important factor.

Plasticized Cement

Florok plasticized cement/dowel system of pile splicing is the only method and material design for use in splicing both preplanned plices
as well as the unexpected emergency or occasional splice.

Florok plasticized cement is a hot melt, fast setting splicing compound. It is supplied in convenient brickett form.
When heated to between 265 and 290 degrees faranheit it melts to a thin, pourable liquid. Upon cooling, which is within 15 to 30 minutes depending on the ambient temperature,
it resolidifies to its origninal compressive and structural strenghts, completely filling all voids and openings.

It has been in use througout the world, sind 1959, as a prestressed concrete pile splicing compound. In addition, it has been used for grouting columns, shear key grouting in concrete beams and floor deck planks,
setting bolts, rails, etc., and wherever speed in setting and economy are of great importance.

Due to it’s special plasticized agents., it has the ability to withstand the shock, strain, and abouse of both hard and soft pile splicing without loosing bond or shattering under impact.

Florok plasticized cement is NOT effected by sea water, salt or brackish water or ground water. It will withstand the effects of underground burial and it is not effected by most acids, sewage or industrial waste.


1. Drive the first section of the pile to a convenient working height.

2. If required, drill holes in the proper pattern, diameter and depth. The holes should be larger than the dowels and their sides, whether cost in place or drilled, should be of a roughened nature and the dowels should have a deformed pattern to provide good mechanical bond. (Avoid smooth surfaces)

3.Dowels may be varied in length to reduce the discontinuity at the end of the dowels. However, the holes to receive the dowels could be of a constant depth to facilitate installation.

4. Place a steel spacer shim 1/2 ” x 1″ x 1″ directly in the center of the top of the first section of the driven pile.

5. Lower the second section in place and line up evenly and true.

6. Using masking tape 2″ or 3″ wide seal the entire space between the two sections to prevent escape of molten cement. Strip back the tape only where the lip of the pouring spout is to rest on top of the first pile section.

7. When splicing long lengths of pile, use a yoke or steel jig for the secure and properly align both sections and to avoid movement or vibrations during cement cooling period. A favorable design includes a small yoke. This allows for a resting surface while securing the yoke as well as to direct the flow of molten cement away from the pile edge and toward the holes to be filled.

8. If the second section to be spliced is a short length, it may be possible to disregard the use of the steel yoke. Use proper spacer or shim as above. Prefabricate light metal pouring spouts, similar to spouts in the
steel yoke, and tape to sections. Use appropriate securing methods, such as guy wires, etc., for safety and to avoid movement for a few minutes while the cement sets up.

9. Depending on the ambient temperature, the steel yoke can be removed as soon as the cement has cooled. (five to fifteen minutes)

10. Redriving of pile can be resumed within 15 to 30 minutes.
