Where repairs are larger, deeper or more complex, the Evermend 4 Hour Cure cartridge gives you the working time you need. The extended cure window means you can build up deep fills in a single application, profile and shape the repair carefully, and achieve a flawless finish without rushing.

The non sag formula holds its position on vertical and overhead surfaces without slumping, making it the go-to choice for window frames, door sills, structural joins and larger rot sections. Like all Evermend products, it bonds with the timber fibre rather than sitting on top of it, creating a repair that is structurally integral and built to outlast the surrounding wood.

Dispensed through a twin cartridge extrusion gun for consistent, mess-free mixing every time. Once cured, the repair can be sanded, drilled, nailed, screwed and painted to match.

Key Features & Benefits

  • 4 hour cure time: more working time for detailed or deep repairs
  • Non sag formula: stays in place on vertical and overhead surfaces

  • Sandable, drillable, nailable and paintable to a seamless finish
  • Application volume: 5–20mm
  • Made in the UK and backed by a lifetime guarantee
  • Requires a twin cartridge extrusion gun (sold separately or in bundle packs)

Durable. Efficient. Effective Timber Repair.​


Evermend offers a premium range of 2 part epoxy wood repair resins, expertly designed to restore, protect, and extend the life of timber.  Our products provide a strong, lasting bond that ensures long-term performance.  Trusted by professionals and DIYers alike, Evermend makes timber repair simple, reliable, and built to last.​


With over 30 years of hands-on carpentry experience—and the last 20 years dedicated to the specialist field of timber window restoration—we understand the value of preserving original character without compromising on quality, time, or durability.


At Evermend, we’ve spent decades demanding only the highest standard of products to match the quality of our work.Traditional timber repair methods often involve splicing or full replacement—costly, time-consuming solutions that can strip away historic features and increase environmental waste.


Enter Evermend—a comprehensive range of high-performance epoxy resin products designed specifically for timber repair. Our solutions are engineered to handle the movement and stress that often compromise damaged or rotten wood.  Evermend allows you to rebuild large, decayed areas quickly and reliably, with a hardened finish that’s even stronger than the original timber.  Every product in the Evermend range is designed for ease, efficiency, and enduring performance—guaranteed for 10 years. Once cured, our epoxy can be sanded back to a smooth, paint-ready finish that blends seamlessly with the original surface.


From our user-friendly cartridge range to our innovative Evermend Pots—which eliminates the need for an extrusion gun—we’re making timber repair simpler, smarter, and stronger.    

           

Preserve the past. Strengthen the future. Trust Evermend.

TIP: We always recommend having all materials onsite PRIOR to commencing any restoration project as sometimes delays occur in the courier network which are outside of the control of Lock and Latch. 

Installation:

Tools required:


- Routing tool to remove damaged timber
- Electronic moisture meter
- Mixing board
- Mixing knives / scrapers
- Extrusion tool
- Plastic cup (for Rebuild Stabiliser)
- Brush (for Rebuild Stabiliser)
- Rebuild Stabiliser
- Rebuild Resin of choice
- Sanding paper

Substrate Preparation:

Cut out and remove all soft, loose and rotten timber and ensure all dust is removed before applying any Rebuild Stabiliser. See the preparation and user information
on Rebuild Stabiliser prior to application of the Rebuild resin.

Application and Mixing:

Press the clutch plate located at the back of the extrusion tool and pull the pistons to the fully back position. Slide the cartridge tube into the extrusion tool ensuring the
smaller diameter tube enters first. The diameter of one of the piston plates is slightly smaller to fit the smaller tube. Unscrew the end cap and squeeze the handle to
extrude the required quantity of filler onto the mixing board. Remove excess filler from the end of the cartridge and replace the cap.

Mix the two products together with a folding action using a putty knife or similar until the green colour fades and an even coloured mix is obtained. This ensures the resin
and hardener are thoroughly mixed. Apply small amounts of filler first to ensure air is not trapped within the repair and then build up using larger volumes. Complete the
repair by smoothing over the surface before leaving to cure.

4 hour cure review

This product is fantastic! Ive used it many times now and it saves me so much time and hassle of splicing. Now I can do many repairs onsite instead of having to take windows back to the workshop to fabricate parts. Once dry, its more solid that the timber!

Great for sills and rotten timber

Rebuilt some rotten window sills recently with this product and the Job came up really nicely. I’d seen this product on Instagram and thought I’ve gotta give it a go and it didn’t disappoint.
Very satisfying to use. The product is firm and doesn’t sag and is extremely strong and flexible.
Which makes it very easy to follow the contours of detailed moulding and bigger holes where products like bog would take 3-4 goes to fill.
I started out using the pots but have now moved to the cartridges so I don’t have to measure out the quantities. Have some builders wipes handy to clean filling blades with because it’s quite sticky.
I’ve been painting over with Dulux 1 step as a primer and it bonds really well.
Easy and quick to order well with the money

fantastic products

I bougt two 4- hour cure catridges, one extrusion gun, and a set of epoxy wood stabilizer from lock and latch. None of them let me down, they are all fatastic. I am a DIYer and I applied these products to my wooden windows, door frames, fascia boards, the bargeboards, a verandah beam and balusters. They are easy to use, with no cracking or shrinking. The product seamlessly blends into the wood once fully cured. The company also has very supportive customer service.

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.

4 hour is 5 star

This product is the rolls-royce of fillers, and I've used them all! Highly recommend for any wood repair, especially external. We've so far used it on door and window frames. If you're looking for a serious product that gets the job done right this is it. Great product, these guys are great to deal with too, I've been dealing with them for years and they really know their stuff

Awesome gear

Recently used the evermend epoxy filler for the first time. Best product I’ve used for repairing old timber. Will always make sure I’m stocked up.

Brilliant stuff

So glad I discovered this epoxy. Used to rebuild rotten window frames at a fraction of replacement cost.
