Why is My Cured Resin Table Cloudy? Causes & Fixes

Q: Practical Tips for Achieving a Clear Finish

Keep your workspace dry: Always work in a low-humidity environment, especially when pouring larger table surfaces. Stick to the correct mixing ratios: Follow your product instructions exactly—most deep pour resins, like EpoxyTable 5-Five , have specific resin-to-hardener proportions by weight. Mix thoroughly but gently: Stir both parts together slowly to minimise the introduction of air. Pour in conditions recommended by your resin: If temperatures or humidity are outside the advised range, consider waiting for better conditions or adjusting your workspace.

Nothing’s more frustrating than uncovering your cured resin table to find it looking hazy or milky. There are a few common reasons for a cloudy finish, and knowing how to prevent them will help you achieve a consistently clear result with your future resin projects.

Main Causes of Cloudiness in Resin Tables

Cloudiness is most often due to moisture in the environment, incorrect resin-to-hardener ratios, or air bubbles becoming trapped during mixing and pouring. High humidity can cause the resin to react with water vapour, resulting in a foggy or matte finish. Similarly, inaccurate measurements between resin and hardener can lead to incomplete curing, which also produces clouding. Finally, vigorous or hasty mixing introduces air bubbles that may remain within the resin after curing.

When This Matters Most

A perfectly clear resin finish is essential for highlighting wood details or casting transparent surfaces in artistic and river tables. It also makes a significant difference for items intended for display or daily use, where haze can distract from the intended design or colour effects.
