The main differences between interior plaster and exterior plaster are their resistance to weather conditions and the composition of materials. Plasters intended for outdoor work usually contain additives that make them resistant to moisture and frost. Interior plasters, on the other hand, are mainly intended for an aesthetic finish and do not need to withstand weather conditions. If you're not sure what type of plaster your project should use, consult a professional. Find the best plasterers on our platform and ask for advice or a quote.
