EPOXYBOG

What is epoxy bog?
First a statement. You cannot use auto filler (polyester bog) on your boat. You may experience adhesion problems on a flexing hull. You will have little protection if water gets to it. Heard of osmosis? There could be shrinkage problems. There could be shadowing with un-reacted styrene monomer, a solvent in polyester bog, reacting with the top coat. EPOXYBOG, our name for epoxy fairing compound, eliminates these problems. The secret is in using epoxy resin as the base. Epoxy reacts with, in this case, an amine hardener, to form a densely cross-linked polymer with exceptional adhesion and strength. It is a pre-filled, trowelable, epoxy putty, that feathers out and sands easily. It is very strong because it chemically cross-links to cure. Adhesion to a properly prepared substrate is exceptional.
EPOXYBOG, an Xtra lite, and creamy low density trade epoxy.

Why an epoxy like EPOXYBOG?
One of the hardest tasks in fairing and filling is getting the mix right.
EPOXYBOG is an EASYMIX 1 : 1 ratio. Off ratio mixing is a thing of the past. There are no messy powders to contend with. Importantly, there are no slump problems. Ever fought with a “roll your own” fairing compound that didn’t want to go where you were troweling it?
You get a much longer “open time” to move it around just right, and the overnight cure is still as good as any.

Where can I use these products?
In marine situations, they are just what’s required for fairing and filling. It is a dream product for filling fibreglass weave, creating coves, and standard fairing, especially where ease of sanding is a consideration.

Below the waterline?
When used sensiby, this is as good as it gets. In the unlikely event of water penetrating to the EPOXYBOG, it will not absorb water as other fillers might. We recommend our EPG 4:1 laminating resin is applied as a barrier coat before fairing and filling. Allow to cure thoroughly before relaunch. After sanding, follow the paint manufacturers recommendation for priming, before painting.

Can I use solvent in the mix?
Definitely not! That is a BIG NO NO!
Solvent, even the smallest amount, weakens all the superior cured strengths. Adhesion, cohesion, etc. Some of the solvent can remain entrapped in the cured film making it rubbery, but without the strength. Problem city further down the track.

Are there Health & Safety issues?
Yes there can be, if used improperly.
Care should be exercised with the uncured resin and hardener. Don’t get it on your skin. If you do, wash it off immediately. Just because it doesn’t burn is no excuse. The side effects are with prolonged exposure.
Wear a dust mask when sanding. A paper mask is OK but make sure it fits.

Because it is pre-made, is it expensive?
Consider this:
The cost of labour is not inexpensive. Wouldn’t it be better to get each mix right, and applied easily with a minimum of fuss in the shortest possible time?
And NO, it is NOT expensive in relation to other epoxy brands. We sell direct to you and our prices are sharp.



TIMBER SEALER
AND PRIMER 1:1

What is it?
Epoxy resins are excellent timber sealers. They penetrate the surface and then set hard. This is a chemical reaction that is very stable and will not resolubilise or break down over time.
Importantly, because of their strength, they assist in the restructuring the integrity of the timber.

Why an epoxy like this EPOXY SEALER?
Our sealer is based on low molecular weight epoxy and amine hardener laced with a wetting agent, for even better penetration. Then we add a high solvency solvent mix to help it go in further before it sets. Finally we add a relatively “safe” broad spectrum biocide to combat any lurking fungi and yeast. Our EPOXY SEALER is different from most others because it cures bright and dry without a greasy surface.

Why a penetrating sealer?
Laminating epoxies are not designed to be penetrating sealers. Neither are epoxy glues and fillers. If the thin surface coat is broken, fungi and yeasts (micro organisms) can attack the wooden substrate.

Where can I use this product?
There are two main areas. Clean new timber, such as the interior of a boat, primarily to seal it against wood rot, and protect against dirt & oil, etc.
The second area is the repair and reinstatement of rotten timber; in the home, or marine.

What is the cause of wood rot?
Fungi and yeasts are micro organisms. They require a food source, the timber, plus moisture, oxygen, the humidity in an enclosed hold, plus some warmth. Given these, they will rapidly multiply and start attacking an unprotected wood surface and quickly travel into the wood along the micro voids that is the timber grain.

Is penetration important?
Micro organisms are just that; micro! They will go deep into the timber grain, as mentioned.
EPOXY SEALER will follow the same paths and saturate much deeper than most sealers.
When it cures, the micro organisms will be trapped within the polymer. Peripheral fungi will be killed by the biocide that migrates out of the film surface.

Can the rot re-occur?
The fungi produce spores which can remain in the timber but cannot regenerate without moisture and oxygen as long as the sealing job is done correctly.

Is it strong?
EPOXY SEALER is designed to penetrate with the aid of a solvent mix. There is the possibility of solvent being entrapped in the cured film. This will weaken the film slightly but not critically. What it is actually doing is allowing the wood to retain its strength.

Can I use solvent in the mix?
Yes you can. Although it is optimized and ready for use, 10% in the first coat will assist penetration. The first coat will probably vanish into the surface. This is a good sign that it is doing its job.

Are there Health & Safety issues?
Yes there can be, if used improperly.
Care should be exercised with the uncured resin and hardener. Don’t get it on your skin. If you do, wash it off immediately. Just because it doesn’t burn is no excuse. The side effects are with prolonged exposure. The epoxy is also flammable because of the solvent carrier. There is a strong odour; the solvent releasing, during application. Take care. Read the instructions.
