EpoxyBog Filler and Fairing Creams

1:1 Easymix xtra LITE & super CREAMY

Epoxy bog filler


EPOXYBOG Fairing Compounds are two unique and novel epoxy products for marine and industrial fairing and filling. The two grades are :-

EPOXYBOG xtra LITE a perfect low density, easy trowelling fairing compound for large areas. Sands easily and retains a feather edge. Designed for commercial fairing of large areas. It still trowels & sands very easily. . Perfect for coving (filleting) also.

EPOXYBOG super CREAMY A medium density epoxy fairing compound. Similar in consistency to automotive polyester filler. Has very good trowelling characteristics, and when cured, sands easily and has good strength They offer superior application properties and cured performance to all fairing products currently available.

Designed for fine fairing of boat hulls with minimal slump, but may be used in any filling or coving application. Have been formulated to exhibit similar fairing characteristics to light weight polyester systems but to have the cured superior adhesion, water resistance, and strengths of an epoxy.

Excellent bonding ability allows it to be used on most substrates. Will cure in thick film with negligible exotherm and shrinkage to a hard, resilient mass, which may be milled, sanded, filed or drilled with ease.

Once you have used a pre gelled easymix 1:1 EPOXYBOG, it will be very hard to go back to messy, off ratio 3 part mixing. (epoxy resin + hardener + filler powder)

  • Very easy to mix and apply.
  • Not much dearer than mixing your own in material cost, but considerably cheaper when ease and speed of application are considered.
  • Easymix, pre gelled similar consistency resin and hardener, 1:1 ratio by volume or weight.
  • Throw away glue powder. Eliminate messy off ratio 3 part mixing. Eyeballing is easier with Easymix 1:1.
  • Only mix enough for the job.
  • Non-shrink, non-slump, non staining, solventless
  • Excellent hydrophobic tendency. An inherent water repellency allows this product to be used below the waterline when over coated with a pure epoxy.
  • Low amount of inorganic silica in the mixture means greater safety during sanding operations.
  • Planes and sands easily with little wear on blades and no clogging of sandpaper.

Purpose designed for fairing and filling in marine and industrial applications Construction repair work

As a moulding material for applying shapes, coving's, (fillets) etc

These systems do not cure like polyesters (5-10 minutes) but requires approximately twelve hours to sandable state. This is necessary as the slowness is inherent to control exotherm with negligible shrinkage, and allow a high degree of adhesion to the substrate.

Not designed as a stand alone product below the waterline, but will give exceptional water resistance. Overcoat with a pure epoxy, EPG 4:1 laminating system. A good rule for below the waterline is:

  • Laminating resin onto hull first
  • Fair with EPG Fairing Cream
  • Laminating resin over Fairing Cream

Timber : Plane and sand surface to a fair condition. Degrease surface if necessary; this is important with oily timbers such as teak. Cross hatch sand with 100 grit paper.

Steel : Degrease surface if necessary. Abrasive blast clean to give a sharp profile. Vacuum away all blasting dust. Alternatively abrade with medium sandpaper. Alternatively, degrease and power wire brush or metal disc clean to bright steel or as best as possible.

Aluminium : Degrease and abrasive blast clean with sand to give a sharp profile. Alternatively use a proprietary aluminium etch cleaner as per the instructions given with the product. Alodine is a well known brand.

GRP : Degrease and cross hatch sand with 60-100 grit paper. Polyester must be fully cured. Take special care as surface wax may be present and must be removed.

Custom wood, Particle board (Bench tops, etc) : Sand as per timber.

Measure out equal quantities by volume or weight onto a flat board and mix thoroughly. Use a wide blade spatula and avoid entrapping air. Mix thoroughly to an even colour.

Do not alter the ratio or you will experience a slower cure and lower physical strengths.

Apply immediately to the clean, prepared substrate.

Use a polyethylene scraper to wipe the EPOXYBOG onto the surface in thin layers. The wiping motion removes air bubbles.

The exceptional rheological properties allow the mixed material to be applied to vertical and inverted surfaces in thick film. Working time is excellent, so larger mixes are possible.

250ml + 250ml = 500ml pack*
500ml + 500ml = 1 litre pack*
1lt + 1lt = 2 litre pack
4lt + 4lt = 8 litre pack
10lt + 10lt = 20 litre pack

*xtra LITE not available in 500ml & 1 litre packs

Do Not interchange super Creamy components with xtra Lite and vise versa. Cure will not be as thorough.
Do Not add solvent to the mixed EPOXYBOG as this will be entrapped in the cured system, and will weaken it.

Because of its’ consistency, this is an unfiltered product. Whilst the raw materials conform to narrow specifications, some discreet particles may be evident. These will sand easily, and overcoating with a 2-component epoxy sanding sealer is recommended.

EPOXYBOG is a technical system, and care must be exercised in its' use.
Use epoxy solvent thinners for clean up of uncured and partially cured resin on utensils.
Ideally, use disposable containers and spatulae.
Keep in tightly sealed original containers in a cool place.
Do not store near boilers or other sources of heat.
Do not store in direct sunlight.
Epoxy resins and their curing agents will cause skin sensitization if in continuous contact. Use disposable plastic gloves to avoid skin contamination. Epoxy solvent thinners should never be used to wash hands.
If resin comes into contact with skin, wash uncured resin off with soap and water.
Wear safety glasses to avoid eye contamination.

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.
