Coating for Weathered Stucco

[Oscar Beteta]

Hi everyone!

I recently bough a old house in the West mount Airy part of Philadelphia. The house is presumably 100 to 150 years old. It has stucco siding that looks very weathered with some hairline cracks is different spots. The stucco itself is not falling off and seems to be in decent mechanical shape with quite a bit of chalking.

I would like to coat this old stucco so that it spruces you the look of the siding and adds a water resistant but breathable layer.

I’m considering either painting it with a masonry paint like what Home Depot sells (Behr brand) or applying an acrylic stucco finish. I’m quite intrigued by the acrylic stucco option as this sounds like a very robust coating that will last a long time.

What do you guys think? What would you do in my case?
