There is no doubt for me but I believe Cascamite is the best exterior wood glue available. If you really want a quality PVA then Titebond Ultimateis a good option that does not require mixing. Are Powdered Resin Wood Glues Waterproof? Although the workshop conditions may be above 10C, wood brought in from unheated storage conditions may well be below this temperature and should be allowed to warm to above 10C before attempting to bond it. Bonding Oak

What we need is a fantastic natural wood glue. Apparently there are no natural wood glues that are not degraded by water in some way, so full-on external use might be difficult, but what about some research on the limits of what does exist? Cascamite One Shot 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. Oily timbers, such as teak, present problems with the “oils” inhibiting a satisfactory bond. (alcohol helps prep oily surfaces before glueing removing some of the surface oil) Degreasing Polyvine Limited, Vine House, Cheddar Business Park, Wedmore Road, Cheddar, BS27 3EB, United Kingdom Store Cascamite in a cool dry place with the container tightly closed. Heat and moisture will cause the glue powder to become solid or insoluble. Claims for loss due to the neglect of this warning cannot be accepted. (unlike PVA Cascamite does not freeze) Cleaning of Tools and Containers

Would it be realistic to laminate the veneers using Cascamite glue and then with the planking complete to finsih the interior and exterior surfaces with epoxy? Are these systems compatible? Stir thoroughly until a smooth creamy paste is produced. It should be the consistency of a ‘runny nose’.

Well, you now have your super-duper glue all mixed and ready to rumble. When I want to adhere two pieces of timber for a permanent adhesion I first make sure all surfaces are clean and dry. Even before I contemplate applying glue I must be sure that the mating surfaced are jointed so there are no gaps.Cascamite is the best-known brand of powdered resin wood glue but what is it? Cascamite is sometimes referred to as UF but it’s technical chemical name is Urea Formaldehyde . This powdered resin is activated when mixed with water yet once set it is waterproof making an ideal glue for exterior use. Powdered resin wood glue is also known as Urea-Methanol, either way, Cascamite is a known carcinogen so dust masks while mixing are essential. Remember Oak dust is also a Carcinogen so care needs to be taken when working with any form of dust. What else is UF glue used for?

Urea-formaldehyde resin adhesives feature a low effective cost, low cure temperatures, resistance to microorganisms and abrasion, and light color. It does not creep, and can be repaired with epoxy. It can rapidly deteriorate in hot, moist environments, releasing formaldehyde (a carcinogen). [9] [10] [11] Supplied as a fine white powder which is mixed with half its weight of cold water for use. Mixed adhesive remains usable for around three hours depending on temperature. Providing it is kept dry, un-used powder has a shelf-life of up to a year. The adhesive has the ability to fill gaps between ill-fitting components. A popular brand is Cascamite. [12] Going a stage further, I read that the Pardeys in their book "Cruising in Serrafyn" didn't have epoxies but applied three coats of creosote to their finished hull before painting. I assume they did this to protect against marine wood borers but there must have been some protection against rot also gained through this process. Could creosote be compatible with epoxy and with cascamite?Simply mix with water gap FillingHigh Water ResistanceInterior or Exterior UseEasy to Mix Non-StainingMould ResistantStronger Bond Than The Wood ItselfMIXINGBy Weight. Use 2 parts of Cascamitepowder to 1 part of cold water. By volumes 3.5 parts of Cascamitepowder to 1 part of cold water.

Cascamite has been used for many years in the UK to produce many different types of boat both sail and power using different construction methods including cold molded. If needed, clamp whilst the glue is wet using pins or screws, keeping the joint under pressure until it has set Do not apply in damp conditions, when rain is likely, or in temperatures below 10°C - between 15°C and 20°C is ideal. My only boatbuilding experience was 30 or more years ago when I built two small wooden boats, both in plywood using Cascamite, a resin glue that comes in a powder that you mix with water. I liked this stuff, it was easy and tough. Preparing lignin-based wood adhesives from lignocellulosic biomass promotes the use of green adhesives and contributes to the development of profitable biorefining schemes. It is a significant advancement in the field of sustainable adhesive technology and has the potential to impact the plywood manufacturing industry positively.The greenhouse gas emissions is 2.04 kg CO2-eq./kg of Urea-formaldehyde adhesive.
