Indicative consumption with a 310 cc PROTECH FLEX cartridge: 5x5 mm joint = 10 linear metres; 10x10 mm joint = 3 linear metres; 15x10 mm joint = 2 linear metres; 20x10 mm joint = 1.5 linear metres
The high versatility and excellent adhesion to different media make PROTECH FLEX the most suitable adhesive sealant for flooring and roofing joints made of concrete, wood products, steel, stainless steel, aluminium, anodised aluminium, galvanized steel sheets, copper, plastics, etc.
The application supports must be perfectly clean and dry, free from dust and soiling. Preliminarily treating the side walls of the joint with the appropriate primer single-component polyurethane PROTECH FLEX PRIMER.
It is appropriate to provide for inserting into the joint, whatever its nature, the specific foamed polyethylene kerb FILTENE FONDOGIUNTO, of the appropriate size to the joint to be sealed.
Prepare an easily removable paper ribbon (coachbuilder ribbon type) on both sides of the joint, in order to prevent the sealant overflowing outside of the natural seating of the joint.
Slowly and carefully extrude the sealant from the cartridge in the specially prepared seat of the joint, with the appropriate gun (of the type for silicone). Before the total hardening of the sealant, spread it to the brim with spatula on the surface of the joint. After hardening, remove the adhesive tape.
Clean any product overflows from the seat of the joint with suitable solvents (like acetone or Nitro thinner).
- Apply by hand
- Dispensing gun
- Nitro thinner
- Cement-based or lime-based mortars
- Prefabricated concrete
- Metal surfaces
- Floor screed
Carry out preliminary adhesion and compatibility tests of paints in case of subsequently painting the sealant.
It is good practice for the depth of the sealing section not to exceed half the width of the joint. To this end, the depth will be determined by the placement of FILTENE FONDOGIUNTO.
Products and accessories for adequately deformable cement osmotic waterproofing, thanks to special, flexibilising agents with a rubber base, particularly indicated for tiled terraces and balconies.
PROTECH BALCONY is a ready to use concentrated single-component solution, made out of silicone-based resins and organic polymers catalysed in solvent. The solution viscosity is lower than that of water, so as to penetrate any cracks liable for water
