Before pouring resin over a shower tray, it’s vital to check that the tray is perfectly flat using a spirit level. This helps achieve consistent coverage and an even, professional finish.
Why Level Surfaces Matter for Resin Application
Resin is self-levelling. If your shower tray is even slightly tilted, liquid resin will naturally flow towards the lowest point, leading to a thicker layer in some areas and bare spots in others. A properly level surface helps you avoid patchy finishes, pooling, and wasted material, ensuring your coating cures smoothly and looks great.
How to Check and Adjust for Level
Place a spirit level at multiple points in different directions across the tray—lengthwise and widthwise. If you find it isn’t flat, adjust by shimming underneath or gently repositioning the tray until the bubble sits square in the centre of the spirit level. This small step can prevent many issues once the resin is poured.
Practical Tips for Flawless Resin Trays
- Double-check the level after any adjustments or movement to the tray.
- Clean and dry the tray surface before you begin resin application.
- Choose a high-viscosity resin like Art Pro Deluxe for best control, especially on vertical sides or edges.
When This Matters Most
Level measurement is especially important if your tray design features decorative patterns, or if you’re applying multiple resin colours that should remain distinct. Uneven surfaces can cause colours to blend unpredictably or flow away from their intended area.
