This guide provides comprehensive instructions on creating a stunning High Gloss Resin Floor, suitable for various settings including homes, offices, garages, and showrooms. It builds on previous projects like ‘Neon Plank Table’, ‘DIY Resin River Table’, and ‘Resin Penny Floor Project’, and was specifically implemented in the studio of Easy Composites Ltd. The techniques discussed here are also applicable to marbled floors, resin art floors, and as a clear coating on decorative floors.

Preparation and Materials

To embark on this project, gather the following materials:

  • GlassCast 3 Clear Epoxy Coating Resin
  • Grey Epoxy Solid Colour Pigment
  • Fumed Silica
  • Scales
  • Paddle Mixer
  • Safety Equipment
  • Spiked Shoes
  • Builders Caulk or Silicone Sealant
  • Notched Squeegee on a Pole
  • Spreaders & Mixing Stick
  • Cleaning Equipment
  • Polypropylene Strip
  • Glue Gun

Step 1: Room Preparation and Calculations

Ensure the room is dry, heated, and maintains an ambient temperature of 20°C. This temperature should also apply to the resin. Calculate the amount of resin needed based on the room’s dimensions and the depth of your pour. For example, a 70m² room with a 1.5mm pour depth requires about 105kg of resin.

Step 2: Preparing the Floor

Firstly, seal the perimeter and any doorways to contain the resin. Fill any cracks or gaps to ensure a smooth surface. Use a mix of GlassCast 3 and Fumed Silica to create a tough epoxy filler, apply it with a trowel, and allow it to harden. Sand smooth any rough spots and thoroughly clean the floor.

Step 3: Weighing, Mixing, and Pigmenting the Resin

Next, ensure all high spots and rough areas are sanded down to achieve a smooth surface, then clean the floor meticulously. It’s crucial to remove all dirt and debris to prevent imperfections in the final finish.

If your floor surface is unsealed or porous, apply a sealer or a thin layer of GlassCast 3 before the main pour to prevent the resin from seeping into the substrate.

Additionally, it’s important to maintain a dry environment as moisture can adversely affect the curing and final appearance of the epoxy resin.

Step 4: Pouring & Curing the Resin

Choosing Colors:
Your personal preference will influence the color or combination of colors for your floor. Experimentation with metallic pigments can add effects such as marbling. We recommend testing these effects on a small panel before committing to the entire floor area.

Mixing Large Batches:
For this project, a solid grey epoxy pigment was selected to achieve a high-end showroom appearance. We used GlassCast 3, which has a mixing ratio of 2 parts resin to 1 part hardener. To manage the large volume, we divided the total resin into three kits, and then each kit into three batches, resulting in nine batches for the project.

Pigment Proportions:
Add pigment at a rate of 2.5% of the total mix volume. Each batch consists of 8.33kg of Resin (Part A), 4.17kg of Hardener (Part B), and 300g of Pigment.

Effective Mixing Technique:
Carefully weigh and mix the resin, hardener, and pigment. Use a powered paddle mixer to blend the components effectively, keeping the mixer submerged to avoid introducing air. Mix thoroughly for 3 minutes before transferring the mix to a second bucket for additional mixing, a process known as ‘double potting.’ This is crucial for achieving a uniform mixture. Repeat these steps for each batch, reusing mixing buckets as needed.

Step 5: The Finished Floor and After Care

Pouring the Resin:
Mark the floor sections where each batch of resin will be poured using masking tape. Start pouring the resin at one end of the floor, and spread it evenly towards the exit, using a hand spreader for areas around obstacles like pipes or pillars. For larger areas, a notched squeegee is more effective. We recommend a notch depth of about twice the resin depth, or 4mm in our case.

Continue the sequence of measuring, adding pigment, mixing, and pouring until the entire floor is covered. GlassCast 3 resin levels itself well, needing only minimal adjustment to ensure even coverage.

Curing the Resin:
Complete the entire floor in one go, ideally with an extra person to assist with mixing, as the process can take up to 45 minutes. The resin releases air bubbles naturally, but if you spot any areas where bubbles aren’t popping, pass over them with a propane torch.

Use spiked overshoes to walk on the freshly poured floor if necessary. Once the pouring is finished, seal the room to prevent drafts that can bring dust into the wet resin. Let the floor cure completely to achieve a smooth, high-gloss finish.

Step 6: Other Applications

The techniques shared here are versatile and can be adapted for various decorative purposes such as adding marbling effects, using the resin as a clear coat over other materials, or customizing colours.
