How To Use

All surfaces must be clean, dry, sound and free of dust, oil, old sealant or other contamination.
Application: 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 deliver the appropriate bead size. Gun FulaFlex 550 PU LM 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 complete contact with the substrates. The application tool should contact the entire surface that is required to be tooled, and may be dipped in solution of detergent/soap and water (approx. 1:5 ratio), ensuring that the solution does not get into the bonding areas.
