How do I estimate resin cost for a river table?

Calculating area and thickness

First, measure the length and width of your intended resin pour area to determine the surface area in square metres. Multiply this figure by the desired thickness (in metres) to calculate the total volume of resin needed. For river tables, the ‘river’ channel usually runs between wooden slabs, and commonly requires between 2cm to 5cm in thickness depending on your design.

Choosing the right resin kit

Look for kits that clearly state both the volume of resin supplied and the recommended coverage per thickness. For deep pours (up to 5cm), products such as the EpoxyTable 5-Five offer reliable guidance on layer depth and spreading capacity, ensuring you select enough for your table’s dimensions. For beginners, a complete kit designed for river tables can simplify the process, as these include detailed instructions and calculate quantities based on common table sizes.

Practical budgeting tips

• Always check the manufacturer’s coverage chart for your kit—these are often calculated for specific layer thicknesses.
• Account for slightly more resin than your calculation to cover any spillages or formwork seepage.
• When comparing kits, consider the total volume, the suitability for thick pours, and included extras like pigments or sealing materials, all of which can influence overall cost.
