Sash Window Add On Weight - Half Pound (0.23kg)
Works well

Worked well and was easy to use. It’s worth getting the cartridge and guns if u want to save a bit of effort, but it is more expensive. They answered the phone quickly when I called with a question.

Cotton Sash Cord 8mm - 100 Metre
Great product

This is fantastic for hardening and stabilizing degraded timber before repairing it with the epoxy filler.

Evermend Epoxy Wood Stabiliser
Fantastic product

This stuff is the best for large wood rot repairs. I used it to fix rotten timber window frames. I had used builders bog before finding this product. It is a much better product. Doesn't sag before it sets and is much stronger than bog.

Evermend Epoxy Wood Repair: 4 Hour Self Mix Pot
Great product low odour easy to apply.

Novice at DIY and found this really easy to use. A bit hard to sand down but it's probably lack of tools. The low odour is a huge +. I have plenty to mend so will be buying again.

Evermend Epoxy Wood Repair: 4 Hour Self Mix Pot
Better than anything else I've tried

Addressing window and door rot. I tried other types of epoxy and filler, but this seems by far the most suitable. It is very "well-behaved", i.e. easy to work into the hole or gap and achieve exactly the profile you want.

Evermend Single Repair Bundle: 4 Hour
Good quality product, easy to work with

Pot product useful for larger fill jobs, easier to use than multiple dispenser based product, easy to mix and use with recommended proportion

Evermend Epoxy Wood Repair: 4 Hour Self Mix Pot
Evermend 4hr cure

this is a great product!!
i think i've tried all of the options on the market and this is the one i prefer the most.
Its easy to mix and goes on more like a gel so its not stringy and messy top apply.
Dries hard but can still be sanded. Doesnt slump do can be used vertically also!
Much quicker than splicing and wont rot from rain exposure. will definitely keep using this one.
