## Questions & Answers

**Q: How much do I use?**
A: Start with 1/2 ounce per gallon of mixture. If darker color is desired, add small amounts (up to 1oz per gallon) until desired color is achieved is spray.

**Q: Is this product soluble in water?**
A: Yes, this product should be used with other water based products.

**Q: Does this product come with measuring device?**
A: Our updated packaging for the 8 & 16 ounce bottles have a built in measuring device. Other bottles & sizes will need a dedicated syringe/measuring device from home. For sustainability efforts, we are selling through current packaging to reduce waste.

**Q: Does this product stain?**
A: This product is very concentrated and undiluted product will stain. Lazer is not permanent and will not stain once diluted. The colorant will fade in time with sun and moisture.

**Q: How do I get this product off of my hands?**
A: This product is very concentrated and can stain hands, clothing, cement, and other objects the concentrate comes in contact with. Over time the color will fade from hands or you can use a 50/50 bleach water mix to fade color more quickly.
