What Happens If I Add Too Much Colourant to Resin?

← Back to How do you pour colour onto floor resin?

Adding colour to resin can transform plain floors into striking feature spaces. However, it’s crucial to understand the impact of using too much colourant to ensure a professional, lasting finish.

Risks of Over-Coloured Resin

When excessive colourant is introduced into floor resin, it can disrupt the curing process. This might result in a sticky or soft finish, ultimately weakening the surface. In addition, too much colourant may cause uneven coverage, leading to patchiness or visible streaks across the floor. Heavily coloured areas are prone to unwanted discolouration and may not achieve the smooth, even appearance you envisioned.

Best Practices for Adding Colourant

To achieve vibrant yet stable results, always add colourant gradually to your mixed resin—start with just a few drops and blend thoroughly before assessing the shade. Most concentrated products, such as the Colourfun Liquid Epoxy Resin Colourant, go a long way. It’s generally advisable not to exceed the recommended dose, as little as 5% colourant by mass relative to resin. By keeping within this limit, colours remain consistent and the structural integrity of the floor is preserved.

When This Matters

Staying within recommended colourant limits is especially important on high-traffic floors or when a flawless, durable finish is required. Overuse of pigment can compromise both the look and longevity of your resin project.
