What Is Epoxy Grout?

Epoxy grout is a high performing compound that is made up of epoxy resin and hardeners. Unlike cement grouts, they are stain resistant, waterproof, and highly durable. Such qualities make them ideal for spaces that are mostly wet and where hygiene and strength is important, which includes pools, kitchens, bathrooms, and other commercial areas.

One of the main reasons why epoxy grout has gained so much popularity is that it is resistant to discoloration. Epoxy grout is non-porous, on the other hand cement grout has the tendency to absorb moisture and take in dirt and mould, making them dark with time. Epoxy grout offers great resistance against chemicals and stains, ending up providing a smooth color-stable finish. However, the question still remains the same, why does epoxy grout turn lighter when it gets dry than when it is being applied. 

Does Epoxy Grout Dry Lighter?

Yes, when drying, epoxy grout shows a lighter shade, although this change in color is quite subtle. However, during application it appears dark and shiny. This is due to the moisture and resin that is not fully cured yet. When applying the grout, water and solvents evaporate, this causes the resin and hardener to react chemically, this chemical reaction shows grouts actual color.

This slight change in color does not show any imperfection or low quality but understanding this behavior can help you improvise your tiling project and avoid surprises after the grout is fully cured and dried. 

What Factors Impact The Color

There are multiple factors that can influence the color of epoxy grout, it can get lighter after drying or vice versa.

1. Ratios: Proper mixing of epoxy resin and hardener is important. Make sure the mixing ratio of both the substances is strictly measured. Any imbalance between these substances can affect the color and its curing time. Always, follow the manufacturers instructions. 
2. Environmental factors: External conditions can also impact the curing time. Temperature and humidity plays a major role. The overall drying time can be delayed if it's too humid or the temperatures too low, influencing the final results. 
3. Type of Surface: The grouting process can also be influenced by the surface porosity. Tiles that are very porous can slightly change the color while its drying. 
4. Thickness: The color of the grout can also change if its applied to thick or unevenly. Make sure that the grout must be applied evenly throughout the surface. 
5. Too Much Cleaning: Too much cleaning or wiping with water can make the grout turn light before it's even fully cured. 

These few factors can help installers understand the grouting behavior properly, helping them achieve the right color after drying.
