Self-Priming:
- Perma-Top needs no additional primer for satisfactory adhesion to concrete.
- Skipping a prime coat puts the floor area back into service faster with less downtime in high-traffic areas.
VOC Compliant:
- Perma-Top is a solvent-free product, permitting its use anywhere a nonflammable, odorless product is required.
- Perma- Top is acceptable anywhere clean air regulations or employee health and safety are a concern.
Impact Resistant:
- Perma-Top has extremely high impact resistance and compressive strength, allowing it to withstand the heaviest of forklift and steel-wheeled traffic.
Kit Packaging:
- Perma-Top comes in one container for easy storage and mixing.
- All neccesary components are included in the shipping container (which can be used as the mixing pail).
Applications & Uses
- Markets
- Application Method
- Compatible Substrates & Surfaces
- Application
- This product can be hand-troweled from 1/8” to 1/4” (3.18 to 6.35 mm) to resurface small rooms or to restore floors to a smooth surface.
- It can also be used to repair holes left by equipment that has been seated in concrete or around the bolts that anchor newly placed equipment.
- Perma-Top can even be used to “ramp” sections of adjoining concrete slabs that are uneven.
- Surface Preparation
- Bring the material to normal room temperature before using it.
- Continuous storage should be above 5°F or the product will crystallize.
- The most suitable surface preparation would be an aggressive shot blast to remove all laitance and provide a suitable profile.
- All edges and around columns or beams should be mechanically scarified.
- All termination points should not be feather-edged but should be sawed cut with the termination ending at the saw cut.
- All large cracks should be V-cut and filled with an appropriate filler.
- All expansion joints should be filled with an appropriate joint filler.
- When overlaying an expansion joint a single saw cut along the joint will prevent random fracturing.
- A test should be made to determine that the concrete is dry; this can be done by placing a 4’ x 4’ (1.22 m x 1.22 m) plastic sheet on the substrate and taping down the edge.
- If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating.
- The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.
- Product Mixing
- No primer is necessary.
- However, a suitable primer can be used.
- Product Application
- The mixed material should be applied at 1/8” to 1/4” (3.18 to 6.35 mm) thickness.
- Apply the material with a hand trowel or other suitable equipment.
- Do not over trowel.
- Maintain temperatures within 55 and 90 °F (13 to 32 °C) during the application and curing process.
- Re-coat or Topcoating
- If you opt to re-coat or topcoat this product, the material must be fully-cured.
- Many epoxy and urethane coatings are suitable for use as topcoats.
- It should be noted that when excessive expansion joint movement is involved, topcoats may chip or crack.
- Floor Cleaning
- Some cleaners may affect the color of the floor installed.
- Test each cleaner in a small area, utilizing your cleaning technique beore cleaning the entire surface.
