FulaFlex Construction GP

Description

Fulaflex Construction GP is a high-performance, isocyanate free methoxysilylterminated silane polymer designed for use as a general purpose construction sealant. Fulaflex Construction GP cures to form a seal that is tough, elastic and weatherproof with good chemical resistance. Fulaflex Construction GP is easy to apply and tool off.

Benefits

• ISO 11600 Type F, Class 25, sub-class LM
• Meets the criteria of a sealant for use in AS3740-2010 (Waterproofing of Domestic Wet Areas) waterproofing applications
• Isocyanate and solvent free
• Highly flexible – 25% of original joint width.
• Excellent resistance to weathering and UV radiation, resists yellowing
• Mould Resistant – Will not support fungal growth
• Excellent long term chemical resistance to seawater, caustic solutions and cleaning agents
• Short term chemical resistance to petrol, grease and mineral oils
• No bubble formation when curing
• Paintable with high build, flexible emulsion coatings
• Strong adhesion
• Sag Resistant

Uses

• Sealing expansion and control joints in pre-cast panels, tiling, walls, roofs, wall, door and window frame perimeters, cladding and brickwork.
• In applications where a level of chemical resistance is required.
• As a waterproofing perimeter fillet beneath waterproofing membranes (refer to HB Fuller technical department for specific membrane recommendations) including those required to satisfy AS3740-2010

Product Application

Cut tip off cartridge. Angle cut nozzle to desired size. Screw nozzle onto cartridge. Apply sealant in a steady, continuous flow by pushing the sealant ahead of the nozzle so that it completely fills the joint and is in contact with both sides. Immediately after application, tool the sealant using a spatula. A dilute soap/water detergent solution may be used to tool Fulaflex Construction GP, although the solution should be pre-tested to confirm it does not affect the sealant in any way, as this can compromise long-term durability. Avoid contact with alcohol or other solvent cleaners during cure. Remember to remove the masking tape before the sealant skins.

Painting

Flexible, acrylic-based emulsion coatings are best over Fulaflex Construction GP. Less flexible interior coatings are likely to crack due to their inflexibility. Oil based coatings and coatings containing a solvent are likely to remain tacky for an extended period when used over Fulaflex Construction GP.

Chemical Resistance

Long-term chemical resistance to fresh water, salt water, limewater, caustic solutions and cleaning agents. Short-term chemical resistance to petrol, grease and mineral oil. Not resistant to organic acids, concentrated mineral acids or solvents.

Limitations

• Avoid exposure to high levels of chlorine
• Do not use in joints deeper than 20 mm
• Avoid contact with alcohol and other solvent cleaners during cure phase
• Pre-testing is required on marble or other highly porous stone – finish may be affected
• Solvent-based coatings may remain tacky
• Do not use on bituminous surfaces
• Do not use on materials that bleed oil and plasticisers or solvents, as this will affect adhesion (e.g. most rubbers)
• Not a fire rated or glazing sealant. Not suitable for glazing use with glass, acrylic or polycarbonate sheets
• Not suitable for use in roofing lap joint applications where the sealant is feathered down to zero application weight – for such applications consider the use of silicone.
• Not suitable for swimming pools or hot tubs
