Features & Benefits

• Uses include:
  • Bedding applications to support precast concrete units, lift shafts, steel stanchions, machines, wooden blocks and baulks, anti-vibration units
  • Bedding steel plates on bridge soffits and decks. Use in conjunction with Tecgrip Resin Anchor Materials – Plate Bonding
  • Fixing of chemical resistant tiles in aggressive environments
  • Fixing of granite marble and stone cladding
  • Fixing of dollies for test purposes
  • Uprating corroded bridge steelwork by the adhesion and bolting technique
  • Bedding of rails on plates for mobile storage applications, eg libraries and document storage
• Structural support of the highest degree
• Acts as a high strength support for arises, cladding, steel and precast concrete elements
• Resistant to a wide range of chemicals including petroleum products and chloride ions
• Freeze/thaw stable
• The natural colour is light grey (near RAL 7030). Suitable mineral pigments may be added to adjust for architectural purposes. (Speak to our Technical Services Dept).
• Tested in accordance with the relevant parts of BS 6319 and EN 1542

Preparation

• Remove laitance and all loose material including dust, oil, and grease to achieve a sound substrate
• Concrete surfaces should be mechanically abraded to produce a mechanical key for critical situations
• Lift shaft surfaces with physical corner location points should refer to engineer’s instructions
• It may be necessary to infill significant holes in substrates and we refer you to Epoxy Mortar E or EFG
• Steel surfaces should be free of mill scale and rust, for ‘plate bonding’ refer to standard preparation details
• Badly corroded steel should be cleaned back to bright metal
• For the majority of work no priming is necessary. For particularly difficult substrates eg porous concrete contact the Technical Services Dept

Mixing

• All components must be used to complete the mix as the ratio of base to hardener is critical
• Pour all the resin into the provided mixing bucket or clean mixing vessel
• In cold conditions, less than 10o C, the base becomes thick.
• The hardener may be added to the depleted base bottle and used to ‘wash out’ the remnants of the bottle. This may be achieved by replacing the bottle top and shaking the contents for 20 seconds - add this to the base
• Mix with a slow speed, high torque electric drill c/w mortar stirrer until homogenous
• Add the filler slowly whilst continuously mixing
• After all the filler has been added mix for a further minute until an even colour and powder distribution has been achieved

Placing

• Depending on the application, place the mixed material onto the prepared surface using a notched trowel, float or suitable hand tool
• Ensure that the applied material is worked well into edges and irregularities
• The cleaning off of exuded material can be carried out when the Epoxy Putty LS has just started to set or mechanically once the material has cured
• Protection of aesthetic edges and details should be undertaken prior to application
• Product to be placed by hand gun can be mixed and carefully placed in a disposable one litre cardboard cartridge and injected
• No special curing practice is required
• Solvent should be used to clean tools and mixing equipment before setting of the Epoxy Putty LS
• Removal of set material will be difficult and will require mechanical methods. Solvent plus clean dry gravel can be an effective stirrer cleanser.

Limitations

• Epoxy Putty LS will not set at temperatures less than 5o C
• Application thicknesses range from feather edge to a nominal 3mm
• For tile and stone cladding applications use notched trowel with maximum 6mm tooth width
