How it Works:
01
Fill to the line
Add water to the fill line on your PlusWater bottle. Tap water works great!
02
Shake it Up!
Give the bottle a good shake. The concentrated pigment activates instantly, transforming into rich, luminous liquid watercolor ready to paint!
03
Paint & Diffuse
Apply to Roylco's Color Diffusing Paper, then spritz with water. Watch colors travel, blend, and bloom into breathtaking patterns - no two ever the same.
04
Customize your color
More water = soft pastel washes.
Less water = bold, saturated color.
One bottle gives you an entire spectrum of intensity!
What make PlusWater Extraordinary
♻️100% Recycled Bottles
Every PlusWater bottle is made from 100% recycled materials. Because brilliant art shouldn't cost the planet. We ship less water, which means a smaller carbon footprint from day one.
👕Actually Washable
Our record? Getting purple out of 100% cotton corduroy after 3 full days of setting in. Pre-soak in warm water before washing and PlusWater comes right out - even the stubborn ones!
🌴Made in South Carolina
Roylco is headquartered in Anderson, SC and PlusWater is proudly manufactured right here in the Palmetto State. Buying PlusWater means supporting small!
🖌️Concentrate = Less Waste
Traditional liquid watercolor ships heavy and is mostly water. PlusWater ships as a concentrate, so each bottle makes 250ml of rich, ready-to-use paint. Smarter, lighter, and more efficient.
Six Colors. Endless Combinations.
Each color is independently crafted for maximum pigmentation and diffusion performance. Mix them together on the paper and watch the science of Capillary Action create art all on its own.

FAQ's
Tap water works perfectly in most cases and is what we use. If you suspect your water is very hard or contains irregularities, distilled water is the safest choice. You can test your tap water with standard water test strips if you're unsure.
