Boat building with Bote-Cote
It's EASY TO USE
There's NO AMINE BLUSH
It's AUSSIE MADE
Bote Cote Marine Epoxy System is based on modern Technology and is much safer to use than most other Epoxies available in Australia. We often have people who are sensitive to old technology Epoxies still able to use Bote-Cote. You can read how Bote Cote is safer than other epoxies in our Information Sheet titled Hypersensitivity to Epoxy.
- BOTE- COTE is an easy to use 2:1 mixing ratio, which is a low toxic formulation free of amine blush under all climatic conditions.
- BOTE-COTE is solvent free and therefore non-flammable
- BOTE- COTE is easily removed from the skin with citrus based hand cleaner or white vinegar.
- BOTE- COTE Marine Epoxy System preserves timbers natural beauty and warmth, vastly reducing a wooden boats maintenance requirements. In fact a modern wood/ epoxy composite boat requires no more maintenance than a fiberglass boat.
- BOTE- COTE even has a non-yellowing UV retarding formulation used to enhance clear exterior finishes and seals the timber making it waterproof.
- BOTE-COTE Marine Epoxy Resin is available with four hardeners to handle all climatic conditions and user requirements:
For further advantages of using Bote-Cote Marine Epoxy Resin over other Epoxies in the market place in Australia, refer to our Why Use Bote-Cote brochure.
Or check out the below videos:
BOTE- COTE is easy to use due to its easy to mix 2:1 ratio and is high in solids and Thixotropic agent to ensure thick coats are applied to guarantee a waterproof finish!
Three coats applied to timber and plywood provides adequate thickness for sanding and over coating to seal against moisture and rot compared with 5 or 6 coats of other thinner epoxies.

Use with fiberglass fabrics to sheath and reinforce.
BOTE- COTE and timber combine to produce strong light, easy to build and durable boats.
BOTE- COTE is ideal for classic boat restoration, and has been used to restore many vintage and veteran boats to their former glory.
Use BOTE- COTE for all methods of modern boat building, including plywood stitch and glue, strip planking, cold moulding, and glued lapstrake and sealing other finishes to make them waterproof.
Boat Craft Pacific have developed a range of specially formulated powder fillers also sold by us, which are the safest available.
Bote-Cote filler powders are provided in three grades.
Sanding Filler~ Light-weight and Easy to Sand for fairing
Gluing and Filleting Filler~ For General Gluing and making fillets
High Strength Filler~ For those ultra-strong joints
BOTE- COTE seals and reinforces timber's inherently high strength-to-weight ratio.
BOTE- COTE makes building boats simple and safe - so much so that it is used by school students for canoe and boat building projects as seen in Year 10 Students Canoe Project and FORSTER Community FIREBUG Build our projects page!
BOTE- COTE and our marine plywoods are used in most up to date kit boats. BOTE- COTE epoxy is also ideal for repairing fibreglass boats manufactured from Polyester and Vinylester as it is much stronger than these two products. Details are provided in our brochure fibreglass reinforced plastics explained. Also Polyester and Vinylester do not stick well to themselves and can delaminate easily. For further information on repairing fibreglass read our information sheet on fibreglass repairs and osmosis.
DRIVE Marine Services supplies plans from leading Australian and overseas designers. At no charge, DRIVE Marine Services readily provides advice on a selection of suitable designs and building methods. We also have the skills to hold boat building seminars.
Essential reading before building a boat is the BOTE- COTE manual "Boat Building with BOTE- COTE" which is 32 pages of essential information for reference purposes when you are not sure of a process or procedure. We also have available a range of technical leaflets and books on most aspects of boat building.
The graphic below shows a steel yacht hull which has been abrasive blasted, sealed with two coats of BOTE-COTE Epoxy Resin. Then the hull has been faired with BOTE-COTE Epoxy Resin, thickened with sanding filler to peanut butter consistency and sanded. AQUACOTE Epoxy Primer was then rolled onto the surface to protect it until the owner is ready to paint the hull with AQUACOTE Top Coat.
Solvents in Epoxy
Solvents in large quantities in Epoxies are detrimental to their waterproofing capabilities and reduce the epoxies strength considerably. No more than 10% Acetone should be added to Bote Cote when wetting out Fibreglass cloth, this should be the only time this is done. For further information on porosity of surfaces that are treated with epoxy with high solvent concentrations - read the article written by Dr Bruce McConkey on the findings of his simple experiment titled Water Resistance of Epoxy Coatings. This article also contains a cost analysis of applying three coats of Bote Cote Epoxy compared to applying a solvent based Epoxy and the two coats of a high solids epoxy resin over it. The time and cost is just not worth it.
Problems using solvents in Epoxy Resins
Solvent based epoxies have serious limitations even if it is one of the well known brands and is not a cost effective option as shown in the cost analysis in the solvents in epoxy brochure. Never use solvent based Epoxy to densify timber coatings because:
The cured finish is not waterproof and is very porous, the large release of solvents is no good for the environment. Also the porosity in the epoxy has significantly less strength than using a high solids epoxy such as BOTE COTE. Buying Acetone and Bote Cote and mixing a 50:50 ratio would be much cheaper, but it is not the solution, you should never add more than 10% acetone to your epoxy mix. Check out testing by Dr Bruce McConrey which shows the limitations of solvent based epoxies
They have to be over coated with a High solids Epoxy to make the surface waterproof.
Clear finishing over these products causes the surface to go very yellow as the additives in the Hardener are not Non Yellowing. We have a non Yellowing Hardener for the Bote Cote.
The TPRDA which is added to the Bote Cote for the 1st coat will allow the Bote Cote to penetrate successfully and start building a waterproof barrier from the first coat. Refer to our brochure on Timber Saturation. Solvent in epoxies reduces the Epoxy strength considerably, as well. Check out the WEST System website in their Technical Bulletins.
Sydney Heritage Fleet
Third coat of Bote Cote marine epoxy resin being applied to the hull of "Kookaburra". A traditional speed boat which plied Sydney harbor in the 1950's taking tourists from Circular Quay to Manly. She is being restored by volunteers at the Sydney Heritage Fleet and will be used for joy rides at boat festivals once restored.
