Description

Plaster should cure for at least 3 days and surfaces must be dry prior to the application of Poly Damp Seal. “In situ” application by low-pressure spray (knap-sack), to saturation and run off. WIPE DOWN GLASS AND WINDOW FRAMES IMMEDIATELY AFTER APPLICATION. Wash hands and equipment with soapy water after using Poly Damp Seal.

DRYING TIME: 1 Hour

ECONOMICS: Primer paint may be dispensed with. Paint yield per square meter is greater using Poly Damp Seal. Bagging and bitumising may be dispensed with. Creates waterproof single skin walling systems.

APPROVAL: Poly Damp Seal has been tested by the SABS. Test results show conclusively that the product meets the requirements of the rain penetration test SABS 0400 [KK 17.1]. A test by Draper Penhall Associates concluded that Poly Damp Seal waterproofing provides an excellent barrier against water absorption. The product has been successfully used over the past ten years.

WARRANTY: The product carries a 5-year manufacturer’s warranty.

Features Water based, UV resistant, compatible with all type of cement based surfaces, Excellent Sealer

Preparation A comprehensive inspection of the surface to be treated must be carried out. New Works Restoration Ensure that the surfaces are clean of any carbons, salts, fungi and other contamination. This can be achieved by using high-pressure cleaners, brushes and organic citric acid. Ensure that the surface is sound and stable with no friable joints, distemper or other faults.

Application Apply Poly Damp Seal wet on wet to saturation and run off. Apply to an area of approximately one meter wide, starting at the highest point, working downwards. It is extremely important to apply the second coat to the first coat almost simultaneously. Failure to do this will result in the second coat being repelled and incorrect application being achieved. Low pressure must always be used to avoid atomisation and bounce off. Tests Poly Damp Seal has passed a number of SABS rain penetration tests on various substrates.

  • Poly Damp Seal is used mainly as a sealer and waterproofer on plastered surfaces and penetrates up to 8mm causing a highly effective barrier against water absorption.
  • It can even be used on painted surfaces but will obviously have less penetration ability (2 to 3mm)
  • It also acts as a primer prior to painting and less paint is therefore needed
  • Poly Damp Seal can be used for damp cure treatment.
  • It can replace expensive waterproofing options like bitumising
  • It can dispense with elaborate options like bagging
  • Poly Damp Seal carries a 5 year Manufacturers warrantee
  • Its effectiveness is backed up by scientific water penetration tests.

The preparation of the surface to be sealed, the preparation of the work area, the general precautions to be taken, the application of the product and the benefits of the product are similar to Poly Brick Paving seal. The main difference between Poly Brick Paving seal and Poly Damp Seal is the level of concentration of the quartz component and the carrying agent in Poly Damp Seal, which make it more suitable for higher porosity materials, and in this case all cement based surfaces.
