Transforming Plastic: The Marble Effect

how to turn plastic into marble

Turning plastic into marble is a process that involves creating a marble effect using urethane plastic or polyurethane resin. This can be achieved by mixing different dyes and thickeners to create a marbled pattern. One example is using EasyFlo 60 Liquid Plastic, which has a short working time, and combining it with PolyColor Dyes to create the desired colour and viscosity. Another method involves using Smooth-Cast® 325 liquid plastic and Ure-Fil® 7 to create a thick and creamy mixture. Additionally, there are innovative ways to transform waste plastics into unique construction materials, such as marble tiles, as demonstrated by Kazakhstani designer Enis Akiev.

Prepare components in advance

To prepare the components in advance for creating a marble effect with polyurethane resin, you will need to gather the necessary materials and tools. Here is a step-by-step guide:

  • Gather the Materials and Tools: Ensure you have all the required materials and tools ready before starting the process. The main components are EasyFlo 60 Liquid Plastic, PolyColor Dyes, mixing tools, and a mould. EasyFlo 60 is a two-part system, consisting of Parts A and B, which need to be combined and mixed thoroughly.
  • Prepare the PolyColor Dyes: Decide on the colour scheme for your marble effect. PolyColor Dyes are available in black, brown, blue, green, red, yellow, and white. Prepare small individual cups or containers for each colour you plan to use. Pour a small amount of each desired colour into its own cup. You will need a separate mixing tool for each colour to ensure thorough blending.
  • Combine and Mix EasyFlo 60 Parts A and B: Following the recommended ratio, combine Parts A and B of EasyFlo 60 by volume (1A:1B) or by weight (100A:90B). Mix these components thoroughly until you achieve a uniform consistency.
  • Consider Using a Thickener: If you want more control over the marble pattern and the flow of the resin, consider adding a thickener to the EasyFlo 60 mixture. This will increase the viscosity of the mixture, allowing you to manipulate the placement and dispersion of the resin more easily.
  • Prepare Small Batches for Dyeing: Dispense small amounts of the mixed EasyFlo 60 resin into the cups or containers containing the PolyColor Dyes. It is important not to pour the dyes directly into the primary batch. Instead, add the resin to the dyes and then individually mix each colour thoroughly. This step ensures that the dyes react properly with the resin, preventing any "bleeding" out of the cured casting.

By preparing these components in advance, you will be ready to proceed with creating your marble effect. Remember to work efficiently as the working time for EasyFlo 60 is quite short, typically around 2 to 2.5 minutes once the components are mixed.

Measure and mix Parts A and B

To create a marbled effect in polyurethane resin, you will need to work with a specific set of tools and materials and follow a strict set of instructions. EasyFlo 60 Liquid Plastic, for example, has a very short working time of 2 to 2.5 minutes, so it is important to prepare all components ahead of time.

First, you will need to measure out Parts A and B of EasyFlo 60 by volume (1A:1B) or weight (100A:90B). Prepare your dyes or colourants for marbling, such as PolyColor Dyes, which come in black, brown, blue, green, red, yellow and white. You can use a single colour or mix colours to create a variety of shades. For example, combining PolyColor Red and PolyColor Blue will create purple. Pour a small amount of each desired colour into individual cups and ensure you have a separate mixing tool for each colour.

Next, combine EasyFlo 60 Parts A and B and mix them thoroughly. You can add a thickener to gain more control over the marble pattern. The thickened resin will not flow as easily, allowing you to control its placement and dispersion. You can use PolyFiber II as a thickener, which is commonly used to thicken polyurethane rubbers and plastics.

After mixing Parts A and B of EasyFlo 60, you will dispense a small amount of the resin into each container with the PolyColor Dye. Do not pour the dyes directly into the primary batch. Instead, pour small amounts of the mixed EasyFlo 60 into each container with the dye and mix them individually. This step ensures that the dyes are thoroughly combined with the resin and prevents them from "bleeding" out of the cured casting.

Prepare PolyColor dyes

PolyColor dyes are available in a variety of colours, including black, brown, blue, green, red, yellow, white, and fleshtone. To prepare PolyColor dyes for creating a marble effect in polyurethane resin, follow these steps:

First, decide on the colours you want to use and pour a small amount of each desired PolyColor dye into individual cups. Ensure that you have a separate mixing tool for each colour to avoid contamination.

Next, prepare the EasyFlo 60 Parts A and B by measuring out equal parts by volume (1A:1B) or weight (100A:90B). Combine these parts and mix them thoroughly.

Now, you can add the PolyColor dyes to the mixed EasyFlo 60. Add up to 0.5% PolyColor Dye to the total mixed weight of the liquid plastic, except for PolyColor White and PolyColor Fleshtone, which can be added to polyurethane resins at a rate of up to 2%. Remember, the higher the percentage of PolyColor, the richer the colour will be.

For the best results, add the PolyColor dyes to Part B of the resin before mixing Parts A and B together, or you can add them to the combined mixture. Avoid mixing PolyColor with Part A before combining it with Part B.

If you want to thicken the mixture to gain more control over the marble pattern, you can add a thickener like PolyFiber II to the EasyFlo 60 before dividing it into cups with PolyColor dyes. Alternatively, you can add the thickener to both the PolyColor dye mixtures and the primary batch of EasyFlo 60 for even more concentrated colours.

Remember, PolyColor dyes are reactive and must be thoroughly mixed with the primary casting material (Parts A and B) to cure properly.

Combine Parts A and B with dyes

To create a marbled effect in polyurethane resin, you can use Polytek's EasyFlo 60 Liquid Plastic, a two-part liquid plastic with a short working time of 2 to 2.5 minutes. Therefore, it is important to prepare all the components ahead of time. First, measure out Parts A and B of EasyFlo 60 by volume (1A:1B) or weight (100A:90B). Next, prepare the PolyColor Dyes desired for marbling. PolyColor Dyes are available in black, brown, blue, green, red, yellow, and white. Pour a small amount of each desired colour into individual cups and ensure that you have a mixing tool for each colour.

Now, it's time to combine Parts A and B of EasyFlo 60. Mix these components thoroughly. By mixing in a thickener, you can gain more control over the marble pattern. The thickened resin will not flow as easily, allowing more control over its placement and dispersion. For example, PolyFiber II can be used to thicken the mixture.

Once you have a homogeneous mixture of Parts A and B, you can begin adding your dyes. Dispense a small amount of the EasyFlo 60 mixture into each container with PolyColor Dye and mix each colour individually. It is important to note that PolyColor Dyes are reactive, and if they are not thoroughly mixed with the A and B components, they may not cure properly and could "bleed" out of the cured casting.

After mixing each colour, pour the PolyColor mixes back into the primary EasyFlo 60 batch. Do not mix the colours with the primary batch; simply pour them in. At this point, you can pour the mixture into your desired mould.

Pour the mixture into a mould

To create a marble effect with plastic, you will need to use a polyurethane resin such as EasyFlo 60 Liquid Plastic or Smooth-Cast® 325. You will also need PolyColor Dyes, which come in black, brown, blue, green, red, yellow, and white. You can use a variety of colours or just PolyColor Black for natural-looking marble striations.

Prepare your desired colours in individual cups, and ensure you have a mixing tool for each colour. Combine EasyFlo 60 Parts A and B, and mix thoroughly. By mixing in a thickener, you can gain more control over the marble pattern. The thickened resin will not flow as easily, allowing more control over its placement and dispersion.

Now, you are ready to pour the mixture into a mould. First, dispense a small amount of resin into each PolyColor container. PolyColor Dyes are reactive; if they are not thoroughly mixed with the A & B components of the primary casting material, they will not cure properly and may “bleed” out of the cured casting. Do not pour PolyColor Dyes directly into the primary batch. Instead, pour small amounts of the primary EasyFlo 60 batch into each container with dye and then individually mix each colour.

Finally, pour the PolyColor mixes into the primary batch and then pour the entire mixture into your mould.
