This adhesive resin comes in bead form that can be mixed with our ColdGlaze thinner or acetone. As the solvent evaporates, the adhesive will give a hard strong bond. Excellent for consolidating soft materials such as chalkware and plasters.

Consolidating with Paraloid B72:
Consolidating, or reinforcing (or strengthening) is required when an item is soft in nature (Chalkware, Plaster, etc.) and is flaking and/or
A weak solution of this adhesive is usually around 95% acetone and 5% Paraloid B72 beads. Exact measurements aren’t required; this is
just a good point to start. Once the solution is dissolved, you can apply it to the afflicted areas. The acetone will penetrate the item and
evaporate off. More than 1 coat can be applied. In areas of heavy damage, you can mix up a 10% solution.
When sealing (or filling) cracks, use a 10% solution and then apply tape perpendicularly to the crack to hold into place while the acetone
To make a bonding (adhesive) solution of Paraloid B72:
100 grams (weight, not volume) of acetone
1 teaspoon of fumed silica
50 grams (again, weight, not volume) of Paraloid B72 beads.
Pour acetone and fumed silica into a jar. Wrap the Paraloid B72 beads into a gauze cloth, tie with string and suspend this in the jar,
allowing it to just touch the acetone mixture. Place a layer of Saran Wrap over the top of the jar, put the lid on and set it aside to allow the
Paraloid B72 beads to dissolve. Do not agitate.
Once, all the resin has dissolved remove the lid, string and the empty bag. Weigh the jar and contents. Swirl the mixture around, and
place the jar in an appropriate area under a fume hood or somewhere with ventilation and allow some of the solvent to evaporate, check on
the weight, and swirl every hour or 2. Once the mixture has lost about 45 grams (weight), replace the Saran Wrap and lid. Allow the
solution to stand until all the air bubbles have disappeared.
Now the adhesive is ready for use. Keep unused portioned sealed to prevent the rest of the acetone from evaporating.
