General points for all resin work

Resins are not simple to work with and you should not attempt resin art if you are not prepared to experience a learning curve. Start small and get to know your products and the correct methods.
Preparation and mixing are crucial for any resin project to be successful. Read and follow all instructions carefully. Only mix the quantity that you will use immediately as resins cannot be stored after mixing. The heat generated in a container of un-poured resin or in resin that is applied too thick can reach dangerously high levels. 
You need to take health precautions when working with resins so read safety and health instructions carefully. This product is an irritant to the eyes, skin and mucous membranes. 
TarbenderTM Counter Top Epoxy Resin by Smooth-On
This is a UV stabilised fast curing resin. It should only be used for thin layer applications of about 1.6mm per layer. The resin is thick (has high viscosity) which enables it to be used on counter tops without building sides around the counter top to retain it. The downside of being thick and fast curing is that air bubble entrainment can be a problem which is why it should only be used in thin layers.
Primarily used to create a clear, hard, high gloss coating on wooden bar counters and to encapsulate 3-D objects. Also use for thin layer resin art during which pigments are added and effects created.
UV Stabilised (slow to yellow compared to non-stabilised resins). Fast curing which reduces the tendency for the formation of amine blush.  
Not approved for food contact and not suitable for heat contact above 80oC (thus not suitable for kitchen counters). 
Manufactured by Smooth-On in the USA.
The ratio of Part A and Part B is 100A : 41B by weight

Normal Applications of this resin system
This is a coating resin that is normally applied in thin layers to create a clear, hard, high gloss finish.
Technically it can be applied in layers up to 6mm thick but we recommend 2-3 thinner layers with maximum thickness of 1.6mm per layer.
Recommended applications for this resin system are the following:
  • Onto wooden counters (e.g. bar counters).
  • Used in resin art where various pigments are added and effects created. 
  • Over photos, paper and fabric as in decoupage art. Paper should be glued down and sealed first.
  • To encapsulating 3 dimensional objects.
Due to the liquid resin being fairly viscous and fast curing this is not the correct resin to use for river tables or similar applications. Thicker coats tend to give problems with air entrainment as air cannot rise fast enough in viscous liquids in a short time. For this reason we refer to this resin as a coating or counter top resin and not a casting resin.
The most important characteristics of this resin system
UV Stabilised
  • It does not yellow easily. But be aware that most resins, including this one, do eventually discolour somewhat. 

Not very prone to amine blush but if this does occur take required steps to remove it. 

  • The lower tendency to amine blush is due to the fast curing time. 
  • If amine blush does occur (most likely in cold moist conditions) then the cured surface must be washed with soap and water then sanded and washed again before adding another resin layer.  We recommend that you read our PDF document on amine blush. 
The liquid resin is viscous (thick).
  • This allows it to be spread in a controlled way over surfaces without excess uncontrolled run-off. Once spread fairly evenly it will self-level to form a smooth glossy finish. There is thus no need to build sides around counter tops that you want to coat. 
  • The fact that it is viscous leads to air entrainment problems so it should only be applied in thin layers (recommended layer thickness is 1.6mm). Torching after application is important to remove air.  
Fast curing
  • This gives obvious benefits and is essential in thin layer applications as thin layers of slow curing resin would take days to harden at lower temperatures. Fast curing also reduces the tendency for amine blush development. 
  • There are two downsides of fast curing: The pot life is short making it hard to mix and use large quantities at one time. Fast curing makes it hard to remove air and this limits the resin to thin layer applications. 

Surfaces onto which this epoxy resin can be applied

  • Never apply resin onto oily surfaces. Do not apply over oil based paints or varnishes.
  • This resin can be applied as a gloss coating over water based paints and varnishes.
    • If oils such as silicone oil or Turbo Cell have been added to acrylic paints to create cells in artworks then let the artwork dry for at least 3 weeks (this time depends on the paints used and drying conditions) and then remove all surface oil. Sometimes cleaning with mild soap and water is adequate but cleaning the art work surface with rubbing alcohol is best. Follow this by cleaning with mild soap and water.
  • This resin can be applied over wood, plaster, cement/concrete, stone, marble, foam, fabric etc as well as over surfaces painted with acrylic paints. It may de-laminate from plastic surfaces.

How to calculate the amount of this resin required

We recommend using a scale and resin mass. This is better than using volume which is less accurate. 

For a roughly square or rectangular shape multiply as follows:
Resin required in kilograms = Surface length in metres  x  Surface width in metres  x  required resin film thickness in millimetres.
For a roughly circular shape multiply as follows:
Resin required in kilograms = 3.14  x  Circle radius in metres  x  Circle radius in metres  x  required resin film thickness in millimetres.

For any other shape try and break it down into rectangles and half circles then calculate each one and add them together.

If your rectangular surface is 1.2m x 60cm and you require a film thickness of 1.6mm
Resin required in kg = 1.2m * 0.60m * 1.6mm
                                 = 1.15kg of resin
Now work out how much of Part A and how much of Part B you need to give you the total requirement of 1.15kg
Ratio for this resin is 100A to 41B
To get 1.15kg total resin:
kg Part A required = 1.15/141 * 100 = 0.816kg (or 816g)
kg Part B required = 1.15/141 * 41 = 0.334kg   (or 334g)
