How do I calculate the right amount of resin?

Step-by-Step Calculation Guide

Begin by carefully measuring the length, width, and desired thickness of your resin pour in centimetres. Multiply these three numbers together to find the total volume in cubic centimetres (cm³). Since 1,000 cm³ equals 1 litre, simply divide your volume figure by 1,000 to convert to litres.

• Length (cm) × Width (cm) × Thickness (cm) = Volume (cm³)
• Volume (cm³) ÷ 1,000 = Resin needed (litres)

For example, to coat a coffee table top measuring 100cm x 40cm with a 0.5cm layer: 100 × 40 × 0.5 = 2,000 cm³, which is 2 litres of resin required.

Choosing the Right Resin

The suitable type of resin depends on your project thickness. For surface coatings or thin layers (1.5mm to 1cm), a product like Art Pro is effective for clear, glossy finishes. For river tables or pours between 2-5cm, a deep pour formula such as EpoxyTable 5-Five is ideal. Always choose a resin formulated for the intended thickness to ensure a proper cure and optimal finish.

Practical Tips and Adjustments

When calculating, factor in a slight excess (around 10%) to allow for resin left in containers or unexpected absorption into porous surfaces. For beginners, a complete kit like the River-Table Complete Kit includes measured resin quantities and step-by-step instructions, simplifying preparation and reducing waste.
