Suitable for any type of joint between prefabricated elements, infills, bodies of different structures, partitions, doors and window frames, flooring. The insertion of a "joint base" filler material has many functions in both static and expansion joints: sizing the joint in the most appropriate shape and measurements for the characteristics of the sealant to be used, reducing the stresses internal to the sealant itself and on the adhesion to the walls; favouring the contact of the sealant with the side walls during joint filling; reducing sealant consumption. Sold in circular sections with a diameter equal to: 6, 10, 15, 20, 25, 30, 40 mm. 10, 15 and 30 mm sections are available ready to ship, other sizes are provided by request only.
Filling the "joint base" for any type of joint between prefabricated elements, infills, bodies of different structures, partitions, doors and window frames, flooring, prior to laying the elastic sealant in the joint itself.
The diameter of Filtene Fondogiunto should be about 25% greater than the width of the joint to allow a stable positioning of the profile and create sufficient resistance to the pressure exerted by the sealant during extrusion. Push with a tool with a rounded tip (free of sharp and pointy edges), capable of crossing the width of the joint, Filtene Fondogiunto, up to the desired depth and so as to leave on the surface an adequately deep seat for the subsequent sealant. Normally the depth of the sealing should be about half the width of the joint. Polyethylene foam is unaffected by solvents contained in the primers, but it is a good idea never to apply the adhesion promoter Protech Flex Primer on Filtene Fondogiunto, in order not to alter the anti-adherence properties. FILTENE can then be inserted into the joint after applying the primer, when the "dust-free time" is attained.

A good rule is for the depth of the sealing (adjustable depending on the positioning of Filtene Fondogiunto) not to exceed the width of the joint itself.
