Parex Epoxy Putty LS

Parex Epoxy Putty LS is an epoxy resin based, filled adhesive

Parex Epoxy Putty LS is an epoxy resin based, filled adhesive. The three-component product consists of a base resin, hardener and bag of specially graded fillers. The resultant thixotropic product can be applied horizontally, vertically and overhead (with care). The product is easy to place using hand tools which include notched trowels, floats and even by extrusion from a cartridge. The adhesive will give structural support of the highest degree and will act as a high strength support for arises, cladding, steel and precast concrete elements. Cured Parex Epoxy Putty LS is resistant to a wide range of chemicals including petroleum products and chloride ions. Parex Epoxy Putty LS is freeze/thaw stable. The natural colour is light grey (near RAL 7030).

  • Easy to use. 
  • Can be placed with hand tools. 
  • Can be applied to a feather edge. 
  • Very high mechanical properties. 
  • Resistant to a wide range of chemicals, including petroleum products. 
  • Stable to freeze/thaw activity. 
  • Can achieve a smooth, aesthetically pleasing finish. 
  • Concrete grey in colour. 
  • Suitable for dynamic loading. 
  • Bonds to a wide range of construction materials. 
  • Originally designed for bedding and support applications in lift shafts. 
  • Ideal for bonding brickslips and stone cladding. 
  • Can be used for numerous bedding applications, including rails on plates (e.g. document storage). 
  • Excellent for bonding test dollies.

Usage

  • 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.
  • Fixing of chemical resistant tiles in aggressive environments.
  • Adhering brickslips.
  • Bonding granite, marble and stone cladding.
  • Securing of dollies for test purposes.
  • Uprating corroded bridge steelwork by the adhesion and bolting technique.
  • Bedding of rails on plates for mobile storage applications (e.g. libraries and document storage).

Application steps

SUBSTRATE 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 a suitable epoxy mortar (e.g. Sikadur-41+).

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 (at least Sa 2). 

Priming
For the majority of work, no priming is necessary. For particularly difficult substrates (e.g. porous concrete) contact Sika® Technical Services.

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 (i.e. less than 10oC), the base becomes highly viscous ('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 (300 to 400 RPM), high torque electric drill with a 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.

APPLICATION

Depending on the application, the mixed material can be placed 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 Parex 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.

CLEANING OF EQUIPMENT

Clean all tools and application equipment using the Sika® Thinner C in accordance with the Product Data Sheet. Hardened material can only be mechanically removed.
