Yes, crepi can be water-repellent depending on its specific formulation and treatment. Crepi, also known as facade plaster or facade plaster, is a mixture of cement, sand and other additives that is applied to exterior walls to protect and beautify them.
To make crepi water-repellent, water-repellent additives are often added to the mixture or a waterproof coating is applied after the crepi has been applied and cured. These water-repellent properties help to repel rainwater and prevent it from penetrating the structure of the wall, improving the durability of the facade and preventing moisture problems.
However, it is important to note that not all crepi is automatically water-repellent. It depends on the specific products and methods used during installation. If water resistance is an important consideration, you should discuss this with your contractor or supplier to ensure that the correct materials are used and the correct treatments applied.
