Refund of Delivery Charges (Cancelled Orders)

If you return an order in its entirety, then your outbound delivery charges will also be refunded (for orders within the South Africa’s Local Area’s.

If you return only part of an order, then the outbound delivery charge refund will be calculated based on the total postage cost of the original order (using standard service) minus the cost to send the items you are keeping (using standard service). Due to the way that shipping costs are incremented, this will often result in no delivery charge refund being due.

Any goods found to be faulty or defective and notified to us within 7 days of delivery can be returned to us for a full refund.

Refund of Delivery Charges (Faulty/Defective Goods)

If you are returning faulty or defective goods, then your outbound and return delivery costs will be refunded in full (for orders from within South Africa’s Local Area’s.)

In the event that you are returning faulty or defective goods which were ordered as part of a larger order then the outbound delivery charge refund will be calculated based on the total postage cost of the original order (using standard service) minus the cost to send the items you are keeping (using standard service).

Directions for Use

Surface preparation

The concrete surface must be clean and free of standing water. Remove any sealer or other material that may prevent adhesion of the Concrete Sealer.


AMT Concrete Sealer requires no pre-blending and should be used directly from the container.


Apply at a uniform coverage by spray or roller application. Product may be sprayed with a hand-held “pump up” sprayer or with an airless industrial sprayer. If roller applied, use a short napped solvent resistant sleeve. Do not over-roll as Concrete Sealer Crystal Gloss is very fast drying and the product will web.

Concrete curing

For the best cure of freshly placed concrete, apply AMT Concrete Sealer as soon as possible after finishing operations and/or immediately after the disappearance of the “sheen” of surface moisture.


When sealing, the surface must be clean and free of standing water. Remove contaminants and stains such as waxes, grease and oil with strong soaps or caustic rather than acids. Badly worn or porous areas may need a second application to attain a uniform seal and surface gloss.


Tools and equipment may be cleaned with AMT Concrete Sealer Brush Cleaner. Run cleaning solvent through spray equipment to remove residual materials and prevent clogging of nozzle in future use.

Sealer removal

Dried, cured sealer may be removed with strong solvents such as Concrete Seal Thinner. Also acceptable are commercial paint strippers (always heed directions and warning labels).
Alternatively, the sealer can be removed by sandblasting or by other similar mechanical action.


  • Material will not freeze in storage but should be allowed to rise to 4°C before application.
  • Do not apply when concrete surfaces or ambient temperatures are below 4°C
  • Do not apply over bleed water or free standing water.
  • Use with adequate ventilation and keep away from open flames. If solvent odour is objectionable, use a water-based product for Concrete Curing.
  • Although compatible with many carpet, tile and foot covering adhesives, a test section is recommended.
  • Do not use as a bond breaker for tilt-up construction.
  • HVAC intake ducts will distribute solvent odour into adjoining occupied areas of the building; care should be taken to block these ventilation vents.
  • No heavy traffic until product has cured.
  • Do not use in areas subjected to hot grease or oils.
  • Not resistant to gasoline or brake fluid.
