Features & Benefits

• Suitable for:
  • Bonding Idrostop to concrete between foundation slabs and vertical walls before carrying out second pours
  • Bonding Idrostop around PVC and steel pipes before pouring concrete
• One-component thixotropic adhesive made from sililated polymers characterised by its high initial tack and rapid final hardening
• Contains no solvents and does not give off unpleasant smells
• Very low emission of volatile organic compounds and is certified as EC1 Plus
• When the product is extruded from the cartridge, it forms a paste that may be applied on horizontal and vertical surfaces
• At +5°C to +35°C it sets by reacting with the moisture in the air to form a plastic bead
• Adheres perfectly to surfaces, including on slightly damp surfaces, as long as they are clean and sound
• Creamy consistency compensates for slight differences in the flatness of substrates where Idrostop is to be applied

Application

• Idrostop Mastic adheres well to a wide range of substrates, such as cement-based and cement-derived surfaces, metal and plastic
• Before applying Idrostop Mastic on concrete, make sure the surface is clean and sound, that there are no traces of oil, grease or wax and remove all cement laitance with a brush
• When applying Idrostop Mastic on steel pipes, make sure there is no oil, grease or lubricating oil on the pipes. If surfaces need to be de-greased use a normal solventbased cleaner such as acetone, ethyl acetate or toluene
• When applying the product on plastic, we recommend lightly sanding the surface before applying Idrostop Mastic
• Idrostop Mastic is supplied in cartridges with a pre-cut nozzle to form a bead of triangular section
• Cut the threaded part of the cartridge, screw on the nozzle, insert the cartridge in a standard silicone sealant gun and apply the product to the substrate
• Immediately after applying Idrostop Mastic on the surface, place Idrostop in position and press it down onto the substrate while moving it slightly in all directions to make sure it adheres perfectly
• The concrete may then be poured after 24 hours
• Consumption rate: Approximately 300 ml every 5 metres of Idrostop
• Clean wet Idrostop Mastic from tools with normal a solvent product (ethyl acetate, petrol or toluene)
• Once completely hardened, cleaning must be carried out mechanically
• Do not apply Idrostop Mastic if the bonding surface is highly contaminated with acid or solvent. Carefully clean the surface prior to application
• Do not use Idrostop Mastic if the temperature is lower than +5°C or higher than +35°C
