OWL Force 10 Tanking Slurry 20 KG

OWL Force 10 is a cementitious waterproofing system that creates a monolithic bond using crystalline chemicals . When mixed with clean water and applied correctly, FORCE 10 forms a permanent waterproof coating to the concrete and masonry and is easily applied by brush, roller or spray

Owl Force 10 Tanking Slurry waterproofs against positive and negative hydrostatic heads of water, and is suitable for use internally, externally, above, and below ground. It is also ideal for use in damp-proofing applications.

  • Suitable for damp-proofing and permanent waterproofing applications on concrete and masonry
  • Resists positive and negative water pressure
  • Superior bond strength - becomes part of the structure
  • Resists salt contamination in masonry
  • Suitable for use above and below ground level
  • Suitable for internal and external use
  • Safe to use in contact with potable (drinking) water
  • Can be applied using a brush, roller or spray
Typical uses

Owl Force 10 Tanking Slurry can be used in basements, cellars, foundations, swimming pools, concrete, renders, brickwork, blockwork structures and lining water tanks, pools and planters, etc.

Substrate preparation

All active water leaks must be stopped using Waterstop (rapid setting plugging compound) before continuing to the next stage of application.

Uneven surfaces

Remove by suitable means, all loose pointing, any remaining render or plaster, wood, dust, grease, oil, organic growth, or other foreign materials that may cause contamination or adversely affect adhesion properties. To create a level surface, Universal Mortar should be applied in line with the relevant data sheet, which is available upon request or can be downloaded from our website. Follow the Universal Mortar priming requirements before application.

Level Surfaces

If there is any exposed steel present, apply two coats of suitable corrosion inhibitor to the exposed steel, by brush. Remove all loose material and surface latencies, i.e. dust, oil, grease, corrosion, and organic growth, preferably by using wet grit or water blasting techniques. The strength of the concrete subbase must be a minimum of 25 N/mm².

Note: Special precautions may be necessary to ensure a continuous waterproof barrier at the wall to floor joints and corner joints. This is to avoid sharp changes of angle in the tanking membrane. The joints should be thoroughly raked out and cleaned prior to an application of Universal Mortar as a fillet seal.


  • Using a brush, roller, or spray, apply SBR Latex, mixed 1:1 (by volume) with water.
  • Allow to become tacky to the touch. This will take approx. 30 mins to 2 hours.

OWL Force 10 is a minimum 2 coat application, with each layer applied at a uniform thickness of at least 1 mm per coat.

Brush and trowel applied:

Apply in even layers using a stiff bristled brush or broom/trowel on vertical surfaces and a rubber squeegee or stiff bristled brush/ trowel for horizontal surfaces. It is essential the first coat is well brushed or trowelled into the surface to ensure a good bond with the substrate. Allow the first coat to harden (approx. 2 - 5 hours). Apply a second coat of Force 10 as soon as the first coat has hardened, but not fully set. Apply the second coat at 90° angle to the first, ensuring a minimum overall thickness of 2 mm.

Spray applied:

Use traditional wet mortar spraying equipment and processes, ensuring the final coat provides a uniform thickness of at least 2 mm.
