FulaFlex™ FR is a high performance, elastomeric and intumescent low-modulus fire resistant construction sealant for use in interior and exterior joint sealing applications. FulaFlex™ FR has +/-25% joint movement capability and has been tested with up to 4 hours rating in accordance with AS1530.4-2014 in joints from 10mm to 50mm wide.
Due to variations in fire rating results using different thicknesses and types of substrates consult fire test reports for specific tested FRL's.
Do not apply to wet surfaces
Fulaflex FR is not suitable for use in water retaining structures or where pooling of water may occur.
In many regions applicators of fire rated sealants require certificaton or licenses - check with local authorities to ensure compliance.
Not for use in water retaining structures unless in conjunction with waterproofing membranes.
Fulaflex FR should not be applied to frost bearing surfaces or if temperature will fall below 0°C prior to the sealant fully curing.
When painted with oxidative drying paints disturbances in the drying of the paint may occur.
Because of the diversity of paints available it is recommended to complete a compatibilty test before application.
Do not attempt to finish/tool the sealant in a joint using the chemicals used for clean up (toluene, xylene, methyl ethyl ketone, acetone and mineral turpentine) as they will irreversibly affect the sealant. Only use those chemicals to clean up uncured sealant from tools and equipment.
Not for use in joints contaminated with oil, grease, wax, dust, corrosion, tar, asphalt, loose aggregate, frost, dampness, form releasing agents or other such coatings/impregnations.
Not reccommended for use on bituminous surfaces or on materials tht bleed oils, plasticisers or solvents, as this will affect adhesion.
Sealing interior construction joints that are subject to movement (up to ±25) in concrete and plasterboard wall systems.
If joint movement is not required, Fulaflex FR can be used as a putty for filling holes in fire rated substrates.
Apply Fulaflex FR in ambient conditions between 5°C and 35°C. Under higher temperatures the sealant can skin very quickly which affects the tooling/working time. Do not apply below 5°C
Insert the sausage into the applicator gun and make a small incision at the extrusion end of the sausage. Fit the barrel end and nozzle, with the nozzle cut to the appropriate bead size.
Gun Fulaflex FR by pressing the trigger to continuously fill the joint - while ensuring that air does not get trapped in the sealant/joint. After filling an appropriate length of joint, smooth the sealant with a spatula or trowel, pressing the sealant into the joint to form the required finish while ensuring the sealant fills the joint and is in complete contact with the substrates. The application tool should contact the entire surface that is required to be tooled and may be dipped in a solution of detergent/soap and water (approx 1:5 ratio). Do not allow the solution to get into the bonding area.
Good joint design in the construction industry necessitates a joint width equal to 4 times the anticipated movement of building components.
The theoretically derived 2:1 movement factor is based on thermal movement alone and doesn't allow for variances at the job site and therefore should not be used. The 4:1 design factor accommodates both thermal movement and wide variations in tolerances of construction materials, fabrication and erection often found in the field.
This will also accommodate joints installed narrower than originally designed. In standard expansion joints, the joints should be minimum 6mm wde. For joints between 6mm and 12mm wde, the depth of the sealant should be the same as the width
