Application, Fitting & Dosing

When sealing leaks, relieve the water pressure before application, if possible. Whilst LS-X is setting, drain system if necessary. Apply LS-X direct from the tube and mould into shape using a spatula, or knife, previously dipped into soapy water to prevent adhesion or dragging. Replace cap immediately after use. Allow a minimum of 2 hours to set. The time required depends on the thickness of the product applied. Spraying with water speeds curing. LS-X may be used as a jointing compound on hot and cold water services, including potable water, in place of traditional materials. Reinforcement is generally not required, but reinforcement fibre may be used on larger pipe sizes.The use of reinforcement material is advisable for larger leaks and higher pressures.
