There are times when it is essential to use a pre-thickened type of rubber using a brush-on application to make a mould of an object. An example of this would be to reproduce architectural ornamentation attached to a wall that could not be removed. Another would be the duplication of large pieces of sculpture. It would be difficult to apply the regular type of silicone or polyurethane used to make moulds by pouring, to do this type of vertical application without them sagging, so a pre-thickened type of silicone such as Gelsil is used.

This is one time the $2.00 shops are not the best way to go. Although they sell packed acrylic paint at a very low price you can do very much better by repacking your own. Plastic vials are less popular than glass ones with screw on lids among the successful plaster painting studios as they have found they have a tendency to leak.

We have been searching and testing many plastic containers with push on lids which are around the size of a 50c coin. We have found these to be quite easily filled and are usually larger than… Continue reading

Question from a customer:

Hello,

I have found your website very helpful & it’s given me hope my ideas may come to life, though I have a few questions.

I am looking at making aquarium ornaments. I have already made some rough caves from a mix of concrete & sand, in a sand mould, that are holding up well, but wish to expand my designs & materials. Some ideas will need me to use cement, though many new ideas I’d like to use recycled plastics with more intricate

I have experimented with the use of metal powders in my casting resin to increase the weight and the results were quite good. I used CraftCast 75 for the casting resin and mixed in up to 50% iron powder to the mixture, making sure I mix the metal powder in before mixing the two parts A + B of the resin together. The reason you add the metal before is because once the resin is mixed, you will only have 2 – 3 minutes to get the resin mixture into the mould before it starts to set.

Answer:

Hi,

The only picture frame moulds that we have at the moment are plastics. These can only be cast with resin if you use a good release agent and one of our slow setting resins. The quick setting resins often generate too much heat for the plastic and cause damage to the mould. You could

Question:

Hi. I was wondering if you can help. I would like to make a plaster reproduction of plastic lunchbox. I intended making a negative mould using latex or silicone. Can you advise me which products I should use to achieve the following?

• No damage at all to the plastic lunchbox. This item is nearly irreplaceable (plastic is black, glossy, scratched. circa; 1969)

My preference would be to use latex, but not sure if it will cure on plastic.
Thank you.
