@@CaptMike thank you. You may have mentioned but what temp should water be when adding to plaster. Mine seems to harden too quickly maybe water is too cold ?
@@CaptMike thank you so much. I’ve been experimenting today and I think I have it figured out. My last few casts turned out great. I was stirring in the powder as I was adding and it started to harden to soon. Now I don’t stir until all the powder is added.
@@ericswires8534 That's the way I do it. I add plaster to the water until the plaster starts to mound up. After the plaster has absorbed all the water it can I stir it all up. Good luck and let me know if you have any additional problems!
Hi Mike, this was such a helpful video. I live in Ireland and I’m sure you know how damp and cold our climate can be! So watching you and listen to you, will really help me with my little projects! And by the way, what a beautiful thing to share with your grandchildren, they will cherish that forever! Thank you so, so much for you help! Andrea 👍☺️🇮🇪.
Good Video thanks. You can get bolder colours using cement colourants. Here in the U.K. It's around £7.00 for a kilo. This will do many mouldings for the price.
I would think you could use concrete colorants just fine. Mostly they are oxides. Just start off with a test batch and see it it effects the plaster adversely.
Great video Capt Mike, thank you! I am toying with the idea of making plaster arts and crafts bits for children to paint. I am wondering what I could do to make the plaster stronger? As things stand if you drop the item it breaks. I saw someone on youtube mixing plaster with pva glue instead of water. I might give it a go but wondered whether you had any tips?
I have seen the tips on using glue in plaster, but have not tried it. You might look into "Investment Mix" I have a video here th-cam.com/video/Gdo_UhxTD-E/w-d-xo.html, and Susan Mcgarry also has one. Hope this helps.
Hi! Do you need to use veg oil if you're using a silicone mould? Also can you use regular acrylic paint on the dried plaster or would you recommend a different type of paint?
A silicon mold should need no release agent. You can use vegatable oil if you like. I haven't noticed it making a difference in painting. Regular acrylic will do just fine. It will work better if you seal the plaster first. Water based acrylic wants to absorb in a lot!
If you are going to use the plaste as a mold you do not want to seal it. If you are casting objects such as statues you can seal them with concrete sealer. That works for me.
@@CaptMike a follow up to can I use wall patch plaster instead of plaster of paris,... I do not recommend it. The cost is 1/2 what p o p is and the set up time is 24 hrs, but the tinsel strength is not near as strong ( broke several parts when removing from moulds ) charkie when dry. Does not dry as hard as p o p, can bet strached after drying and does not have the nice pearlized finish that p o p has, over all the price difference is well worth it.
I really don't have a ratio of water to plaster, what I do is first put as much water in a mixing bowl as I think I will need, then slowly add plaster until it starts to heap up just above the water. Let that sit a minute until the plaster have absorbed water and then stir.
Plaster will "set up" in less than an hour. It depends on weather, additives and such. After the plaster has gone through it's heat phase it can be unmolded, but I recommend a longer wait, say 4 or 5 hours. Now you have to wait for the plaster to dry out before you can use it, say for a mold. Hope this helps.
@Capt Mike You mentioned not to wash the cups and others stuff with plaster residual down the sync. I will do this experiment on my apartment. How can I clean those up? I assume it will get hardened if I don't clean them sooon
@@-Harambe clay builds up over time, but plaster will harden pretty quick. When you get a stopage just remove the P-trap under the sink (the J looking thingy) and flush the clay out. Plaster might be a bit harder to remove.
Sorry, but that is the way it turns out sometimes. That is what the "back button" is for. Thanks anyway for the comment and watching at least part of my video!
Thank you for your videos now i have a clue how to do this with my children . They will have many hours of fun . 🙂
They will have fun! Just remember to get it out of their cloths before it dries and don't pour it doewn the drain.
I truly appreciate the tip on the large sack of plaster. You were correct that the small buckets get costly.
Thanks for watching!
Best tutorial! Thank you!
Thanks for the nice comment and for watching!
Thanks sir. Going to start with my son's hands at 2 years old. After the hand mold who knows what's next with the rest . Awesome
Good luck and thanks for watching!
Just the sort of basics tutorial I needed with working with plaster. Great video.
Thanks for watching
This is the most helpful plaster casting video I have found after H O U R S of searching! Thank you!
Thank YOU for watching!
Best plaster video out of all I’ve seen so far. Thank you. 😃
Thanks for watching!
@@CaptMike thank you. You may have mentioned but what temp should water be when adding to plaster. Mine seems to harden too quickly maybe water is too cold ?
If I remember correctly, warmer water accelerated the setting. Not 100% sure of that so let me run a couple of experiments. Maybe make a video.

Love the way u share about plaster casting! God bless
Thank you for watching!
I enjoyed your video, your accent, and your humor. I am about to make plaster bats for my pottery studio. Thanks.
Thank YOU for watching my video!
Soothing presentation
Thanks for watching!
Thank you, very helpful
Thank you for watching!
You have to seal your work to protect it from the elements. Glue and water mixture. Mod podge outdoor.
Thanks for watching and for the tip!
Thank you! I am using plaster my whole life but obviously, I was mixing it wrong :)
If it works for you it can't be wrong. Thanks for watching!
Cool fish!
Great advice. Thank You!
Thank you for watching!
This is like bob ross but for plaster casting 😂 this was helpful
Thanks for watching!
Seus vídeos me inspiram! obrigado!

Thank you for watching!
They now make a colorant for cement that will give you a more vibrant shade.
Thanks!
Your voice reminds me so much of Bob Ross ❤
Thanks for the comparison, but Bob was a real artist and I just love crafts!
Thanks!
Thanks for watching!
So helpful, thank you!

@@CaptMike Thank you Capt Mike x
I've been advised to mix up plaster the usual way then stir in PVA to the mix. I don't think ratios matter...just go by gut feeling

can I use plaster wall patch instead of plaster of paris
I'm sure it would work, however do a little price comparison to see what is more cost effective.

how much plaster for how much water do you use?

Do I need to wear mask working inside with plaster mixing?
It is always advisable to wear a mask when dealing with particles as fine as plaster. Thanks for watchang and commenting!
