The ruling on praying while paint remains on the walls

Question:
May Allah reward you with good. This is a worker who works with paint on the walls, and this dye remains on his hand during the ablution. Does it prevent the water from reaching the skin? And what is the ruling on praying in such a case?

Answer:
Praying is not permissible until he removes this paint and performs the ablution, because this paint hardens on the skin and prevents the water from reaching it. He should remove it before performing the ablution, then perform the ablution and pray. As for leaving it, his ablution is not valid, because the water did not reach what is under the paint. Yes.
