Very nice! Can you please tell me where you purchased that mould please ? Thank you

[@MBFibreglass]

Hi, We had some polycarbonate cnc'd and then we made a mould with our silicone materials.

[@juliepierce2066]

@@MBFibreglass so are you selling this mould and/or others that you have made ? Thanks

[@MBFibreglass]

@@juliepierce2066 We made this for ourselves with the materials we sell, unfortunately we do not make for others

Do you know which one is good for candle vessels the 100 I think it is are 730 in this stuff

[@MBFibreglass]

We have many customers using either and/or both.

Thank you for the video, the etching part is really interesting! I have been coating white styrofoam to look like stone walls but I recently ran out of Jesmonite ac100. Would the AC730 be very similar and not damage the foam? As I noticed the product is cheaper and in stock most places.

[@MBFibreglass]

The AC730 is jesmonite's cement based system, (the ac100 is gypsum based), it can be used in a simialr fashion as the ac100 although its a little more viscious to pour in comparison to the ac100. Coating the polystyrene generally shouldn't be a problem but worth testing a small kit to ensure it suits your requirements.

@@MBFibreglass Thank you for the reply, I purchased ac100 to finish the styrofoam. However AC730 looks very useful and will be something I will try in the near future.

Can i make my own jesmonite? In my country (Brazil) no one know whats is it :( Please help me

[@sscott4028]

Hi, can this be shipped to the US? I reside in California and I am not sure how to buy.

[@MBFibreglass]

unfortunately we only ship within the UK & Ireland at the moment, you could try the manufactures website for a distributor in the US.

Is it strong enough as an overlay on existing tiled floors with appropriate prep of the tile?

[@MBFibreglass]

we've not heard of anyone else doing this, maybe best emailing the manufacture tech team for information.

[@AlexParton]

What kind of silicone is that? I'd like to make my own molds to do the jesmonite in.

[@MBFibreglass]

The particular rubber used in this demo is the Polycraft S-30 RTV Silicone, the Polycraft GP-3481-F RTV silicone is also very popular

[@teaandart]

Could you tell me how much powder and liquid you took for this mold ?

[@MBFibreglass]

The final part weighs in at approx 430 grams. The mix ratio is 5:1 for the AC730

[@jaderibeiro7226]

What alternatives would you recommend to ac730? What’s a good substitute?

[@MBFibreglass]

Hi, we wouldn't carry a substitute for the ac730

[@cassiaharkin1646]

Hello, I have the ac730, what ratio do you recommend I use?

[@MBFibreglass]

We recommend sticking to the manufactures recommended ratio of 5 parts Powder : 1 part Liquid by weight.

What are the difference between jesmonite and resin

[@MBFibreglass]

Jesmonite ac730 is an acrylic modified cementitious composite, most other casting resins tend to be epoxy, polyester and polyurethane.
