Surface Preparation

1. The concrete mix design should be free of any cement replacement materials such as fly ash, slag or silica fume, or waterproofing admixtures. Ensure Ordinary Portland Cement/ Type A, G.P.(General Purpose) or S.L.(Shrinkage Limited) cement is specified only.
2. PWC must be applied to a clean, dry, dust free concrete surface.
3. New concrete must be at least 28 days old. Renders may be treated after 7 days.
4. Any materials that retard penetration such as curing compounds must be removed prior to application.
5. Old or carbonated concrete requires Calcium solution treatment to reinstate free Calcium.
6. Where segregation or voids are apparent, chip out, treat with PWC, and then make good with cementitious materials.
7. Pour structural slabs to fall lines where possible. No protective screed is required.
8. For large or stubborn cracks, grind out and flood crack with product. A Calcium solution may be required to bulk up the product in large cracks. Fill with a non-shrink or polymer modified grout, or revert to an elastomeric sealer if there is a possibility that the crack is working or volatile. In large cracks where pruduct runs through quickly, use waterproof tape on the underside to pond product in the crack.
9. Good concrete practice must be followed such as adequate curing, compaction and vibration.

Application Procedure and Equipment

1. Locate all cracks and flood with solution first ensuring they are filled with product.
2. Apply the solution to the remaining area at the rate of between 4-6m²/L.
3. When surface become touch dry (2-6 hours depending on wind condition and ambient temperature) - flood spray the treated areas with water. First watering must begin at maximum of 6 hours even if product still wet.
4. Day 2 - 24 hours late water again.
5. On day 3-24 hours later water again.
6. After the third watering, pond the treated area for the minimum of 12 hours to verify a waterproof seal has been achieved.
7. Introduction Manuals detailing the background of the product and a Technical Bief of the scientific testing undertaken are available upon request.

1. Protect glass, aluminium, wood and painted finishes from overspray.
2. PWC is not suitable for sealing working / volatile cracks as a result of structural defects or caused by mechanical damage. Nor will it provide continual crack healing in concrete mixes containing fly ash, slag, silica fume or waterproofing admixtures.
3. The product on its own is not suitable for sealing where segregation and voids are likely such as construction joints.
4. Nor suitable around penetrations where there is a non - masonry / cementitious interface.
5. PWC is not suitable for negative hydrostatic pressure applications such as the inside face of a basement / retaining wall which is continually wet.
6. Do not apply where ambient temperatures are below 5^oC or above 35^oC
