is there a warning on the back label saying this contains a chemical that may cause cancer?

Hi, yes there is, although that is only if it were ingested. As long as you use it to spread on your walls and do not eat it, it will be fine. Thanks!

Is this good enough to fill cracks up to 1/4 inch ?

Hi, yes, this will fill a 1/4 inch hole no problem and will not shrink either. Thanks!

Can this be used to fill a small hole on hardie board siding? Is it paintable after drying?

This easily fills picture nail holes in walls prior to painting, but it didn’t work as well to fill the holes left after removing small plastic anchors. After several applications, with more than adequate drying time between each, the divots were still visible. The fluffy consistency doesn’t work well with a spackle tool. Your best bet is to go to the store and buy a little tub of the stuff that starts out pink and dries white. I’ve had 100% success with that. But to answer your question, yes, it is paintable after drying.

My walls are textured with something like a sponge and I need to fill some small holes. Can I texture this stuff when applying?

I believe you would be better off using a vinyl spackle or dry wall mud. This product is probably too soft and brittle for a textured application.

Muy bueno y fácil de aplicar

Cumple con lo que dice el producto. No venía seco pero tuve que agregar un poco de agua para que su aplicación fuera más fácil y efectiva. Seca muy rápido por lo que al usarlo debes aplicarlo rápido y darle la forma deseada antes de que seque. Muy buen precio.
