Post mix for setting your posts
Pour it dry into the hole around the post, add water and let it set. Order it with the timber so everything turns up together.
How many bags
As a guide, allow one bag for each 3x3 or 4x3 post and two for each 4x4. Gate posts and large holes take more. Follow the instructions on the bag for setting times.
