Uses: For bedding and external fronting single glass into primed softwood and hardwood frames which will subsequently be painted. Can also be used to glaze primed metal frames and single glass into concrete or stone surrounds after prior sealing with an appropriate sealer. Do not use directly against laminated glass . Do not use for bead glazing systems. Do not use on insulated glass units. Directions: Remove all dust, grease and loose material from the rebate. Any moisture on the timber should be wiped off using a clean paper towel or other absorbent material to give a dry surface. Check the condition of the primer on the frame, especially the rebate. Any section, which has been partially missed or is considerably weathered should be re-primed before glazing. Rebates of hardwood frames which are to be protected with clear varnish should be sealed with a Timber Sealer. Apply putty to rebate and insert setting blocks. Place pane on setting blocks, centralise, press into putty to give a back bedding of 1 – 2mm throughout and secure pane mechanically with clips or pins. Location blocks should be used in side hung opening windows to hold the glass in place. Apply further fronting putty and tool at an angle finishing about 2 mm below the sightline. Brush putty with soft brush to seal to glass. Tool off back bedding, sloping away from glass. The putty must be painted as soon as the putty has formed a skin firm enough to accept the actions of over coating. Apply the first coat usually within 7 - 21 days. The final coat should be applied within 28 days.

FAQs
Can I use this putty on UPVC windows?
This putty is specifically formulated for wood and primed metal frames and is not designed for use on UPVC or plastic window systems.
How long does the putty take to fully cure?
The putty forms a skin suitable for painting within 7-21 days, and the final coat of paint should be applied within 28 days. Full curing can take longer depending on environmental conditions.
Is this product suitable for exterior use?
Yes, it is designed for glazing frames, including exterior applications, provided the frames are properly primed and the putty is painted over once it has formed a skin.
Can I use this putty to fill large gaps in wood?
While it can be used as a general wood filler, it is optimized for glazing. For very large or deep gaps, other dedicated wood fillers might be more appropriate, but for typical frame repairs, it is effective.
What is the difference between this and a silicone sealant?
Linseed oil putty provides a rigid, paintable seal for glass in frames, ideal for traditional glazing. Silicone sealants are flexible and typically used for weatherproofing joints and gaps where movement is expected.
Do I need to prime the frame before applying the putty?
Yes, it is essential to prime the frame, especially the rebate, before applying the putty to ensure good adhesion and durability.
Troubleshooting
Putty is too hard or too soft to apply.
Ensure the product has been stored correctly. If too hard, try warming it slightly in a controlled environment (do not overheat). If too soft, it may indicate improper storage or age; consider replacement if consistency cannot be achieved.
Putty is not forming a skin for painting.
Ensure application conditions are suitable (e.g., not excessively humid or cold). Check that the putty was applied to a dry, primed surface. If application was too thick, it may take longer to skin. Avoid disturbing the putty during the curing phase.
Glass is moving or rattling after putty has set.
The putty may not have been applied with sufficient pressure or back bedding. Ensure setting blocks are correctly placed and the putty is pressed firmly against both the glass and frame rebate.
Paint is cracking or peeling from the putty.
The paint may have been applied too soon before the putty had fully formed a skin. Ensure the recommended painting timeline (7-21 days for first coat) is followed and that the putty is sufficiently firm.

Setup, Compatibility & Care Instructions
Preparation is Key:
Ensure the rebate area is free from dust, grease, and loose material.
Wipe away any moisture from timber rebates to achieve a dry surface.
Inspect the frame's primer. Re-prime any weathered or missed sections.
For hardwood frames to be varnished, seal the rebate with a Timber Sealer first.
Application:
Apply a layer of putty to the rebate.
Insert setting blocks to support the glass.
Place the glass pane, center it, and press firmly into the putty, ensuring a 1-2mm back bedding.
Secure the pane with mechanical fixings like clips or pins.
For side-hung opening windows, use location blocks.
Apply the fronting putty and tool it at an angle, finishing approximately 2mm below the sightline.
Use a soft brush to seal the putty to the glass edge.
Tool off any excess back bedding, sloping it away from the glass.
Painting:
The putty must be painted once it forms a skin firm enough to withstand over-coating. This is typically within 7 to 21 days.
Apply the final coat of paint within 28 days.
Compatibility:
Use for glazing wood and steel frames.
Suitable for concrete or stone surrounds after prior sealing.
DO NOT use directly against laminated glass.
