Help please with a stucco question.

New colored plaster (stucco) has been applied to my backyard. It is all properly prepped with a brown coat and then the color plaster over it.

The problem: The weather was very different on the two different days they applied the final plaster. Consequently the color of the large wall bar b que is different from my low planter walls.

Can they do a thin skim coat over smooth plaster to correct the color of the small planter wall area? Or do they have to chip it off and start over?

Thank you!

Adding more color to re-coat a new color coat.

25% is easily measured using three cups. A color pack is measured by measuring two equal parts in 2 cups.

Measure that half in halves and you have 25%.

The reason for adding 25% more color is for recoating color stucco finish. If stucco is recoated with a color coat or colored white portland, the result is the color is lighter (whiter). The color can be adjusted by adding 25% more color. Expo stucco (now defunct) says 20% more color. To me 25% is easier to measure and we have had good results.

This may help in your situation.

What I would do: No chipping off. The wall can be recoated with a thin coat of your basecoat material using a chemical bonder 50-50 with water. Then, recoat the whole wall outside corner to outside corner the same day.

I wanted to share this 25% method. If you recoat a cement color coat with a new color coat, it will come out much lighter. The 25% method compensates for the lightness and your wall should look fine.
