TanTan Onetan waterproof agent + water based paint, colorant/TanTanNice

We applied a mixture of TanTan Onetan waterproof agent, water-based paint, and water-based colorant.
Both come out well in color,
In the case of a TanTan Onetan waterproof agent, it's better to mix the colorant than the paint
The waterproof effect is good.
The best way to improve the waterproof effect is to apply the waterproof agent first and to apply water-based paint.
