One of the characteristics of edding permanent spray is its very high degree of surface hardness. It is durable for both indoor and outdoor applications and is resistant to scratches, impact and knocks. The durability of edding permanent spray can be enhanced by using the appropriate primer. Before painting, it should be noted that our sprays contain acrylic paint which is intended for decorative purposes. Depending on the amount of use, everyday objects will show signs of wear before long.
