Pros & Cons of Concrete Dyes
Pros & Cons of Concrete Dyes
In the world of architectural concrete, your coloring method can have a major impact on aesthetics and longevity. So how do you know if concrete dye is the right choice? We’re examining the pros and cons:
Pros: Dyes have really taken off in the last five years. Depending on the dye chemistry, manufacturers will use water or solvent as a carrier. Dyes offer the contractor a huge color pallet to choose from, and unlike acid stain, you have access to bright bold colors as well as earth tones. The colors produced by dyes can be more monochromatic, which can be a plus or minus depending on the desired look of your finished project. I think the big selling point for dye is the reduction in installation time and labor compared to acid stains. If you are using solvent as your carrier, it is possible to color and seal in the same day, which saves you a ton of time.
Cons: The major problem with dyes is that they are not UV stable and will fade with exposure to UV. This only makes them suitable for interior floors. Additionally, if you are using solvent as your carrier – especially acetone – it can be very dangerous. The risk of a flash fire is very real and you should make sure you have adequate ventilation and eliminate all ignition sources on the jobsite. I personally know contractors who have been injured by flash fires while spraying dyes in acetone. It’s not something to take lightly.
