SKU: N/A Category: Tags: , ,

A1 Base material is a two-component material that consists of a mineral powder and a water-based acrylic resin.

These components bond to create a very strong material. A1 is environmentally friendly, safe to work with, fire resistant, easy to use and has a fast processing time.

It is important to weigh and mix A1 very carefully, based on the following mixing ratio: 1 part A1 Liquid to 2 parts A1 Powder. Fill a mixing cup or bucket with the amount of A1 Liquid required. Use the stainless-steel High Shear Mixer to create a swirl and then add the A1 Powder. Stir the mix until smooth and lump-free and then stir for another 30 seconds. Make sure that the material on the bottom and sides of the cup or bucket is mixed in properly too.

We supply the following sets:

- 3 kg (1 kg A1 Liquid, 2 kg A1 Powder)
- 15 g (5 kg A1 Liquid, 10 kg A1 Powder)
- 37,5 kg (12,5 kg A1 Liquid, 25 kg A1 Powder) - standard bag size

    I cannot believe how easy it is to use Acrylic One. It sets in a short while, I can de-mould , and get my mould working again after only 30 minutes, and once it cures it is incredibly hard. I am so happy I came across A1. Thank you.

    I was delighted to use and explore the uses for the ACS – Acrylic One product supplied by AUSTRALIA COMPOSITE SOLUTIONS for my sculpture exhibited at the 2021 Sculpture by the Sea Cottesloe. I was greatly impressed with the ease and simplicity in preparing and applying the product to a high-density foam mold. I have used similar products previously and do not think I could have achieved the level of smoothness and capture of detail to the finish in the end result with alternate products. The instructions for mixing and preparing the product were concise and applicable for the project I was completing. I brushed the product directly onto my mold positive repeatedly to create the depth of the product to ensure it was robust enough for a completed sculpture. It was not unduly difficult to sand back intermediate layers and the drying time was quick enough for my overall schedule. Assistance provided directly by AUSTRALIA COMPOSITE SOLUTIONS in using the product was extensive and prompt. Congratulations Mani I am impressed with the product and the results I achieved and certainly endorse the A1 composite product.

    A1 was the first acrylic resin I’ve tried and I’m so happy with how my products are coming along. It was so easy to use, has super quick drying time and finishes so hard! The manuals/tutorial videos Mani have provided were so helpful and he was always more than happy to help me with any questions I had! Would definitely recommend A1 to anyone looking to try something new.

    Great Product! Easy to work with and pigments pop with it, I cant stop making enough with it. have re ordered multiple times and will keep coming back! Mani is always a pleasure to deal with and is very helpful

    I am using A1 to produce homewares for my business and it’s been great. It sets fast allowing you to produce more in a short period of time, and once it has fully cured is incredibly strong. Its heat resistance qualities make it perfect for my products. Also the wide range of pigments is amazing, allowing for many beautiful colours by using them on their own, and endless opportunities when mixing them. As this is for a business, i’m super pleased with the fast delivery and Mani has been incredible with fast response times and available for questions I have about the product.

  9. Tanya Williams (verified owner)

    I have just started using A1 and OMG I love it. Can’t wait for my pigment set to arrive and start experimenting with more colours.

  10. Marek (verified owner)

    This is a great product. Always consistent and so easy to work with. Good resources for material support and fast delivery. Very happy and will be using it more in the future definetly

  11. peachesandapril (verified owner)

    Such an easy versatile product to work with. I love the quick turnaround in regards to demoulding, very low to nil odour, it feels safe to work with and love that you can colour it. I make homewares for my little shop with A1.

  12. Katelyn Pomroy (verified owner)

    Great product! Quick delivery and works well for my homewares business. Smooth pour, minimal bubbles and no sweating in the mold. Very impressed with A1

  13. Monique Bracks (verified owner)

    Continually impressed with A1. The quality of material is excellent with minimal to no air bubbles. Perfect product to use for my needs!

  14. Terracast

    I changed over from a similar product available in Sydney, which was never in stock, and wasn’t giving me a consistent smooth finish, both in texture and colour. With A1 , and A1 Super White, I am happily achieving blemish free product. The Super White, although is takes a little longer to mix, gives me a White, White casting. I am so happy I changed to A1, I’m hooked for sure!!!

  15. Shallan (verified owner)

    Super smooth material that has a lot more working time for mixing custom colours. Also is set in a quick amount & needs hardly any sanding if at all!

  16. Cristine

    I am glad I changed to A1, it is by far superior to all other brands I have used, and I have tried everything available. Thank you Mani for the great service.

      Hi Cristine, thank you for the review, and your support.

  17. Trudy

    I have tried a few eco resins, and I found A1 is by far the best. Strong and hard wearing, and easy to mix and pour. I recommend A1.

    • admin (verified owner)

      Thank you for your review Trudy, and I am glad you prefer A1

  18. Celeste

    I have been using other products which are on the market, and believe me I have tried them all. A1 stands out in a different class to the rest. A little more expensive, but by far more efficient. It would be nice to have larger quantities available on your webshop.

    • admin (verified owner)

      Hi Celeste, I do offer larger quantities, but due to shipping varying so much, it is best to send an email enquiry to

    Since I started using A1, I don’t have any wasted casting. Your pigments are value for money, they just last and last.
