1. Waterproof rainwater drains
2. Waterproof through pipes
3. Vacuum carefully all dust on surface.
4. Apply on all surface SUPERSHIELD VAPORSTOP, liquid water based crystalline vapor barrier, deep penetrating, compliant to norm EN 1504-2 and EN 13580 : water absorption 3,8% e resistant to alkali: 6,8%, depth of penetration: EN 14630: Class 2 - 17,8 mm., reaction to fire: Euroclass A1, dosed a 0,2 l./ m2. Wait for 24 hours before applying the following treatments.
5. Apply on the perimeter and around passing structures SUPERSHIELD FLEXSTRIP 80/150, elastic self-adhesive butyl waterproofing strip, inserted between two coats of SUPERSHIELD FLEXI, cement / polymer liquid membrane
6. Apply by roller or low pressure pump a first coat of SUPERSHIELD ROOFON, waterproofing polyurethane aliphatic liquid membrane, single component, water based, UV resistant, permeable to water vapor, thermo insulating (white), with high crack bridging capacity, compliant to norm EN 1504-2, CO2 permeability at norm EN1062-6: 310 m., strength of adhesion to indirect traction EN 1542: 3 N/mm2, permeability to water vapour EN 7783-1: class I, Sd <1,3 m., capillary absorption EN1062-3: <0,007 kg*m-2*h-0,5, solar reflectance ASTM E 903-96: 91%, elongation at break ASTM D412: >600%, dosed at 0,5 kg/m2, after diluting it with 5/10 % clean water and turning it up on the walls for at least 15 cm.
7. When the first coat is still fresh, apply the SUPERSHIELD ELASTIC MESH, polypropylene mesh (thickness 0,6 mm., weight 60 gr/m2, lateral elongation at break EN 527-3: 180 N/ 50 mm., longitudinal elongation at break: EN 527-3: 240 N/ 50 mm., lateral deformation at break: 105 % longitudinal deformation at break:38%), overlapping the sheets by 5 cm.
8. Apply crosswise by roller or low pressure pump a second coat of SUPERSHIELD ROOFON, waterproofing polyurethane aliphatic liquid membrane, dosed at 0,5 kg/m2, not diluted and turning it up on the walls for at least 15 cm.
9. Apply by roller or low pressure pump a first coat of SUPERSHIELD INFRON, waterproofing polyurethane aliphatic liquid membrane, abrasion and UV resistant, compliant to norm EN 1504-2, CO2 permeability at norm EN1062-6: 310 m., strength of adhesion to indirect traction EN 1542: 4,2 N/mm2, permeability to water vapour EN 7783-1: class I, Sd <0,89 m., capillary absorption EN1062-3: <0,013 kg*m-2*h-0,5, solar reflectance ASTM E 903-96: 91%, elongation at break ASTM D412: >150%, dosed at 0,2/0,3 kg/m2, after diluting it with 5/10 % clean water. Turn it up on the walls for at least 15 cm.
10. Apply crosswise by roller or low pressure pump a second coat of SUPERSHIELD INFRON, waterproofing polyurethane aliphatic liquid membrane, abrasion and UV resistant, dosed at 0,2/0,3 kg/m2, not diluted, adding 5 % in weight of SUPERSHIELD GLASSSPHERE and turning it up on the walls for at least 15 cm.
