How Much Colourant Should You Add to Resin for Floors?

← Back to How to pour colour into resin for floors?

If you’re preparing a resin floor and want to add colour, it’s essential to understand how much colourant you can safely mix without affecting your resin’s finish and durability. Getting the balance right ensures professional, lasting results.

How Much Colourant to Use

As a general rule, do not exceed 5% colourant by mass of your resin component. This limit helps maintain proper curing, hardness and surface quality once the floor is set. Too much pigment can weaken the final result or cause incomplete curing, so always weigh your resin and measure pigment with care.

Some products, such as the Colourfun liquid colourant, are highly concentrated, making it easy to achieve vivid or translucent shades while keeping within this guideline.

Practical Guidance for Mixing

Start by thoroughly pre-mixing your resin and hardener, then slowly add your colourant in small increments. Stir well to check opacity and spread—the high pigment load in professional pastes and liquids means only a few drops may be needed for bold coverage. For a fully opaque floor, continue blending until the desired shade is reached—never rush past the 5% limit.

Always follow product-specific instructions—some systems may recommend even less.
Do a small test pour first to check the result.

When This Matters Most

Strictly observing colourant limits is especially important when creating high-traffic or large-area resin floors, where consistent colour, even curing, and toughness are crucial for longevity and professional presentation. This care applies whether you’re using Colourfun shades or another compatible pigment.
