Cascamite Powdered Resin Wood Glue, only requires mixing with water to make it ready for use. Used for many woodworking applications including veneering, laminating and assembly.
Cascamite is a brand name used for powder urea formaldehyde resin adhesive, often referred to as a “one shot” adhesive. Powder urea formaldehyde resin adhesives are commonly used in woodworking applications for veneering, laminating and joint bonding.
While both Cascamite and PVA glue are used for bonding wood, they differ significantly in their properties and applications. Cascamite is a powder that requires mixing with water to activate. Once prepared, it creates an exceptionally strong and rigid bond that resists “creep,” meaning it won’t slowly deform under constant pressure. This makes it ideal for structural applications, curved laminations using vacuum presses (where maintaining shape is crucial), and situations demanding long-term durability. Cascamite also boasts a long shelf life in its dry powder form.
In contrast, most common PVA glues are ready-to-use, single-component liquids, making them very convenient. Being water-based, PVA is easy to clean up before it dries. While offering good strength for general woodworking, PVA bonds are typically more flexible than Cascamite and can be susceptible to creep under sustained loads. PVA glues also tend to have a shorter shelf life compared to dry Cascamite powder.
Therefore, the choice between the two depends on the specific project requirements: for demanding structural bonds, curved work, and long-term stability, Cascamite is often preferred, while PVA excels in general woodworking tasks where ease of use and cleanup are key considerations.
Advantages of Cascamite:
Exceptional Strength: Creates a very strong and rigid bond, often stronger than the wood itself.
No Creep: Resists deformation under constant stress or load, making it ideal for structural applications.
Excellent Water Resistance: Provides a high level of water resistance, suitable for exterior projects and areas exposed to moisture (though not for continuous submersion in some cases).
Long Shelf Life (as powder): In its dry powder form, Cascamite has a significantly longer shelf life compared to other liquid adhesives, provided it’s kept dry and cool.
Good Gap Filling Properties: Can bridge minor gaps between uneven surfaces, offering more forgiving joinery.
Suitable for Vacuum Bag Pressing: The rigid glue line is excellent for maintaining the shape of curved panels constructed with vacuum bag presses.
Mould Resistant: Offers resistance to mould growth.
Non-Staining: Generally does not stain wood.
Disadvantages of Cascamite:
Requires Mixing: It’s a two-part adhesive (powder and water) that needs accurate mixing before use, which adds an extra step compared to ready-to-use options.
Limited Pot Life (after mixing): Once mixed with water, the adhesive has a limited usable time (pot life), which is reduced in warmer temperatures. You need to work relatively quickly.
Sets Hard and Can Damage Tools: The cured adhesive is very hard and can quickly blunt edge tools if you need to remove any excess.
Can be Brittle Over Time (in some cases): Some sources mention that older Cascamite bonds might become brittle over very long periods.
Not Always the Most Convenient for Small Jobs: Mixing a small amount can sometimes be less convenient.
Can Have a Strong Odour (uncured): Some users report a noticeable odour when working with uncured Cascamite, requiring good ventilation.
The following list gives an indication of Cascamite cure times based on ambient and hot press temperatures. Please note that heat penetration time will vary according to the density of the wood, moisture content, and distance to the furthest glue line. The pressing time must also be considerably extended when bonding less absorbent, or high-density materials.
Cold Press Time:
10℃ – 8 hours
15℃ – 5 hours
20℃ – 3 hours
25℃ – 2.25 hours
30℃ – 1 hour
Hot Press Time:
70℃ – 3 minutes
80℃ – 2 minutes
100℃ – 1 minute
We do not recommend glueing at temperatures below 10℃. If this cannot be avoided then a period of 2 – 3 days may be required before the glue cures. During cold temperatures, make sure that joints under pressure are kept warm.
Mix: Mix 2 parts by weight of Cascamite with 1 part by weight of water. It is not recommended that Cascamite is mixed by volume.
Use a dry container, preferably non-metallic, and add the water to the powder gradually, stirring to ensure the powder is evenly dispersed.
The mixed adhesive is then ready to use.
Note: The addition of too much water will seriously reduce the rate of setting, particularly at lower temperatures.
Apply: Use a brush, hand roller or mechanical roller to apply an even layer to one substrate.
Coverage: Adhesive coverage between 100 and 400g per square metre are suitable depending on the surfaces to be bonded.
Press: Lay the substrates to be bonded together within the workable time and press them for as long as necessary to achieve the required handling strength.
Cascamite glue is made from powdered urea formaldehyde resin, which is a thermosetting resin produced through the chemical reaction of urea (a solid crystal obtained from ammonia) and formaldehyde (a reactive gas obtained from methane).
When stored properly in its original, tightly sealed container in a cool, dry place (ideally between 5℃ and 25℃), Cascamite has a shelf life of at least 6 months.Towards the end of its shelf life, the viscosity may increase and the gel time may decrease.
Cascamite is not the best choice for boat building. Cascaphen is a professional, two-part glue which has been specially developed for waterproof exterior use. This glue has been developed for the marine industry and is the only completely waterproof adhesive that will withstand continual immersion in water.
Cascamite is a powdered resin wood glue, known for its strong, weatherproof, and gap-filling properties, suitable for both interior and exterior joinery, cabinet work, and laminating.

Cascamite does the job very nicely!
Richie (verified owner) –
The cascamite we all know is back! Thanks to Ureka. As keen cascamite users know its not been the same over the years. The new Ureka Cascamite will take you back to the days when Cascamite was Cascamite!
Robert Fletcher (verified owner) –
Great to see Cascamite is back how it once was!
Glen Wood (verified owner) –
Only the amount of glue is required is made up so less chance of wasted glue.
Ben Tyeman (verified owner) –
Excellent , just like the old Cascamite I used to know, I will be using it again.
Nick Steele (verified owner) –
Excellent, easy to mix, very effective, and with a good long open time allowing stress free glue ups!
Peter (verified owner) –
Cascamite is second to none if you are a serious carpenter and are able to wait it cures properly.
Juliet Page (verified owner) –
Thank you very much for the advide given, it has been excellent and so helpful. We make really bespoke finishes and dont use the One Shot for what it should be used for. Up to the last batch it has always worked really well, where we spread the One Shot over the canvas let it cure and then crack it for effect.

I as a Joiner 40 years ago have used Cascamite resin wood glue by the bucket full on windows and doors ETC. and it was the best, even 40 years later on a back gate door frame, yes the wood is rotten but the Cascamite joints are as good as the day i made them.
Polyvine took over making cascamite and it was useless for the last decade, would not mix properly…
NOW thank goodness UREKA make it and it is SUPPERB,
Few, i have the perfectly made waterproof wood glue back for external Joinery.
TICK V G to UREKA FOR MAKING IT LIKE IT WAS ORIGINALLY…
I was so pleased i phoned up Ureka Customer Services and congratulated them on Producing the product as it was..
Well done UREKA.

Don’t remember a time where cascamite has let me down. Been using it since mid 80’s
