Useful tips

Dyofix SPI products are very concentrated dyes that will stain skin and clothing, so always wear gloves and take care when handling.

The water quality in different areas will vary from very hard to very soft so we do NOT add any other chemicals to our products.

If you work in an area that has hard water, you can use readily available products, for example Calgon tablets to prevent the build up of calcium etc in the tank and spray heads.

If the spray heads are set to create a fine “mist” try to keep the heads close to the ground to avoid drifting.
