Apoxie Paste - Semi-Fluid Two Part Epoxy For Repairs and Moulds

About.com Rating 4 Star Rating


The Bottom Line

Apoxie paste is a two part epoxy made by Aves. Listed as a 'semi-fluid', part A is a thin paste, while part B has the consistency of thick honey. When mixed they make a thick molasses type of epoxy mixture, very sticky but easily spreadable and with a slight flow. This is mainly a paste used for repairing small cracks or filling gaps. It will also 'glue' broken sections of many materials together, including plastics, wood, foam, ceramics and other materials. Its use for moulds is limited to moulds where the product does not need to flow into areas where air may need to escape.


  • Life of product can be extended by keeping in the refrigerator or freezer.
  • Slight flex after hardening - for completely non flexing use Aves Fixit Paste.
  • Easy to use, listed as non toxic, but not safe for use by children, good for many repairs.
  • Can be tinted with oil or acrylic paints or colorants while mixing, otherwise dries a kharki color.
  • Can be smoothed or textured with water moistened tools, soap and water clean up before product sets.


  • Very sticky, handling this product takes a bit of getting used to, have water or solvent close by.
  • Long set up means some repairs need to be support while the paste cures.


  • Thin paste epoxy with some flow. Very sticky initially, less so as it begins to set up.
  • Can be tinted with pigments, acrylic or oil paints. Type of paint used affects handling a bit. Base color is Khaki.
  • Good for crack or chip filling, repairs, and some flexible molds.
  • Soap and water clean up before setting, although Aves Safety Solvent is a bit faster.
  • Can be painted and sanded after curing. Can be used in ovens with polymer clay (after curing)

Guide Review - Apoxie Paste - Semi-Fluid Two Part Epoxy For Repairs and Moulds

Apoxie® Paste is a very sticky two part epoxy with a thin paste consistency. Its suggested uses are for use in moulds, or filling chips or cracks in a variety of materials. Gloves are suggested for handling this material (nitrile or vinyl) when blending parts A and B which must be stirred together thoroughly before use. The product has some flow, and can be used in silicone moulds, provided air bubbles do not need to escape through the material. It is too thick to allow this easily where moulds contain very small parts, unless the moulds are quite shallow.

Working time is 1-3 hours with a 24 hour cure. The paste gradually begins to stiffen within fifteen minutes of mixing, but continues to have some flow for at least 30 minutes. If a thinner paste is required the instructions suggest heating part A in hot water or in the microwave in short increments to thin it, blending it with part B when cooled. The consistency allows the product to be trowelled on for larger applications. Once applied to a clean surface it tends to stay put and is not runny. It can be used in very thin coats as a glue for doll and ceramic repair and is safe for repairing plastics or coating foam - it does not eat foam. (I would test plastics and foam first.) Thin coats are somewhat translucent.

Apoxie® Paste has 0% shrinkage and therefore no cracking. It can be sanded and painted. It is non-flammable, and does not give off any fumes. It is listed as non toxic, although warnings are given for sanding. The product cleans up with soap and water, although Aves recommends use of their Safety Solvent, which cleans the product up quickly without the fumes and danger of acetone.

Differences from Aves Fixit® Paste are that Fixit® Paste is safe to a higher temperature (450 ˚F vs 300˚F for Apoxie® Paste ) and Fixit® Paste is resistant to acids, fuels and uv rays as well as giving a stronger bond. Apoxie® Paste is Khaki colored and Fixit® Paste is white.

Aves have a pdf (Acrobat Reader required) sheet comparing Fixit® and Apoxie® Pastes posted online at their home website.

Suggestions and Tips for Use - Apoxie® Paste is an excellent crack and chip filler for miniature sculpts or repairs to a number of materials. It has some flow if used quickly after mixing, or if Part A is heated before mixing as per instructions from the manufacturer. I was pleasantly surprised by its ability to work in simple silicone moulds, although in smaller sections trapped bubbles can be a problem. Matching quantities to mix is tricky, as one product is a viscous liquid, while the other is a paste. I recommend using small measuring spoons used only for this purpose. If you are using the product for repairing broken collectibles, mix very small quantities at a time, to make sure the product is thin enough for easy spreading. The same is true for filling flexible moulds. Successive layers will bond to each other, so fill small mold areas first, and mix and add a new batch after any bubbles have been shaken through the small first pour.

Availability and Price Aves products are available from a number of online sculpture and repair specialists or from Aves online shop. Apoxie® Paste costs roughly $7.50 for two fluid ounces.
