Heritage Putty is an elastic, paintable hybrid polymer-based cartridge applied putty for the installation of single glass, insulating glass units and reduced sightline / slim units into softwood, hardwood, steel and stone frames.
Suitable for glazing where the appearance of a traditional putty front is required, such as for the restoration and replacement of glazing in period properties, listed buildings and conservation areas.
*Note: Compatibility of Heritage Putty with the edge sealants used to construct insulating glass units and the interlayer of laminated glass is based upon experience. We do not have any reasons that indicate any incompatibilities, however, the formulation and type of edge sealants and interlayer film used can be changed by the manufacturer at any time. Due to this; compatibility cannot be guaranteed. The glazing method employed should be based on the glass unit / laminated glass manufacturer’s instructions.
**Paintability: Paintable with both water and solvent based products. It is recommended that due to the availability of many different paint types that compatibility tests are conducted prior to painting. Heritage putty can extend the drying time of solvent based paint systems. The use of water based systems can be considered to avoid this. Skin formation and curing times of Heritage Putty will vary depending upon temperature and humidity, lower temperatures and low humidity will extend rates of cure. For best results it is recommended to apply paint a few days after glazing.
Application temperature range: +5°C to +30°C Priming: Surfaces should be primed accordingly, depending upon frame / substrate type. Shelf life: 12 months when stored in cool, dry conditions. Skinning time: 20 minutes Working time: 10 minutes.
Surface preparation: All surfaces must be clean, dry and free from frost, grease and loose materials. Apply primer if required. In situations where an especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed Cut the top of the screw thread off the cartridge and screw on the nozzle. Cut nozzle to correct diameter for joint size. Apply using a skeleton or powered gun into the joint ensuring good contact with surfaces.
Tooling: Tool immediately after sealant has been applied within the working time for the product. Cleaning: Excess uncured material can be removed mechanically and surfaces cleaned with white spirit.
