Hi from a fellow Saffa..saw the SA flag on the plaster of paris and had to find it..off to buy some now. Thank you for this video and the one on painting, very informative.
Hi Mari...it's a pleasure
How would you add glue to the mix to make it strong
In my experience adding glue to the mixture made it crumble.ans not set well. It would be better to cast your shape, leave it to dry and then paint glue over the dry shape.
Please help when taking out my moulds they seem to stick and break like the star fish ones
A few things could be possible: it's a good idea to spritz water in the mould first. Second make sure your mixture is not too liquid...about 50: 50 works well. Thirdly make sure the plaster has hardened before taking it out the mould. Lastly be gentle when removing delicate shapes and don't force the plaster shape out. Try to get a little air between the mould and the shape and that should release it. I hope this is helpful. Thanks for watching :)
Can I add glue instead of water to make it stronger?
I did try to add glue once and the mixture didn't set properly. It might be better to let your shapes dry and then paint diluted glue over it if you are concerned. Thanks for watching
Where can I get those trays in Johannesburg South Africa please 🙏
You could try the baking store or a craft shop
@@colleenseymourcrafts5802 thank you so much 💖
Why not make a mixture first then pour it in the molds?
I found that way was wasteful for my purposes as I often made up too much...but it is another way to do it
I would make the mixture in a jug and fill the molds I think k that looks very messy ...just a thought
Do u have to bake it after ?
Not at all. The plaster of Paris is set when it's dry. Thanks for watching.
Why don't you do the mixing in a separate container and then pour it into the mold??
Good question...firstly it is easier to control the consistency this way and secondly you don't waste any. I hope this helps...no right or wrong way.
I have never ever seen plaster mixed this way inside the cavity of the mold, but it really is a good technique to avoid mixing too much!!! I suppose you can easily tell that you have enough or the right amount of plaster to the water because we are actually looking for a mix that resembles milk, do we not? Or is it thicker than milk?
@@mariae6942 It needs to be thicker than milk. Just add plaster until it fills to the top of the mold and the plaster has soaked up most of the water. Don't overfill the mold or you will have to do unnecessary sanding once it's dry. Don't forget to tap the mold a few times to get the air bubbles out.
This technique is for someone pouring little ornaments. If you are pouring bigger molds make a mixture first. My old is going mad!!! Lol
I mixed prior to pouring and one time used too much water and the pieces came out chalky snd brittle. How do you make sure the proportions are correct when you do it directly into the mold?
