Flexlock pasta
Flexlock paste is a single component Bitumen Polymer liquid membrane designed for multi purpose projects.
The material features excellent adhesion, which dries to a tough, black seamless flexible waterproof membrane.
Flexlock paste exhibits excellent elongation and recovery properties and is suitable for high speed airless spraying applications. Moreover, Flexlock paste can behave as a vapor-proof liquid membrane.
Flexlock paste, has been authorized and approved by an international lab to block Radon Gas.
In addition, Flexlock paste is CE approved for roofing, ICC approved for below grade waterproofing.
Product Uses:
-Waterproofing underground structures
-Waterproofing basements & cellars
-Waterproofing wet duty rooms
-Protection and dump proofing of underground concrete elements
-Waterproofing covered roofs and verandas
-Аs a repair structure for Flexlock membrane
Benefits & Advantages
Absolute waterproofing | High productivity | environmentally friendly | High strength and elasticity | Easy application | Excellent adhesion | Radon-tight |
Same product grade for various applications | No need for Reinforcing Fabric on most substrates.
Instructions for use
General instructions for all applications:
1. Flexlock paste may be applied by airless spray, roller, brush, or squeegee.
2. All surfaces to which Flexlock paste is applied must be sound, stable with an even finish and free from dirt, dust, loose debris, oil, grease etc.
3. Flexlock paste may be applied to damp but not waterlogged surfaces.
4. Porous surfaces should be primed with a priming coat of a water-based Primer
5. Let dry for about 2-4 hours.
6. New concrete can be waterproofed 48 hours after casting completion
7. Where subsequent coats are to be applied, the first coat must be dry.
8. The waterproofing layer has to be protected before backfilling with soil. Protect the waterproofing membrane with Pazdrain or Pazdrain plus dimpled sheets.
The compaction of the backfilled to a distance of 2 m (6ft) from the wall should be done by a manual vibratory hand held compactor.
No heavy compaction equipment should be allowed to travel close to the waterproofed wall. The backfill should not contain any stones over 40 mm.
Waterproofing of horizontal layers should be protected with nonwoven geotextile with a CBR puncture strength over 1000 kN (BS EN ISO 12236), and a layer of screed or concrete.
A. Below Grade Waterproofing (well drained soil)
1. Apply by airless spray / roller / brush / squeegee, a first layer at a quantity of 1.5-2.5 kg/m2 (3.0-5.0 gal/100 sq.ft).
2. Let dry for 4 hours.
3. Apply a second layer at a quantity of 1.5-2.5 kg / m2 (3.0-5.0 gal/100 sq.ft).
4.Let dry for 12 hours.
B. Walls with dampness
1. Apply three layers, achieving a total quantity of 3.2 kg/m2 (6.5 gal/100 sq.ft).
Blind the final layer with clean sharp sand whilst still tacky.
2. Re-plaster using a render modified with an acrylic alkali resistant emulsion.
C. Wet duty Rooms
1. Apply two layers achieving a total quantity of 2-3 kg/m2 (4-6 gal/100 sq.ft) per each layer.
2. Make sure that the first layer is dry before the second layer is applied.
D. Covered roofs and verandas
1. Make sure that all surfaces are sound, stable with an even finish and free from dirt, dust, loose debris, grease etc.
2. Apply with a spraying machine / roller / brush / squeegee, a first layer at a quantity of 1.5-2.5 kg/m2 (3.0-5.0 gal/100 sq.ft).
3. Let dry for 6 hours.
4. Apply a second layer at a quantity of 1.5-2.5 kg / m2 (3.0-5.0 gal/100 sq.ft).
5. Let dry for 12 hours.
6. Сover with a nonwoven geotextile with a CBR puncture strength of over 1000 kN (BS EN ISO 12236)
7. Сover with a sound layer of screed or concrete slopped to drain
