Is DIY Mortar Mixing Viable for Beginners in Cordwood Projects?

Measuring and Mixing Techniques for a Workable Mix

To create a workable mortar mix for cordwood masonry, beginners should follow a simple recipe: one part cement to one part lime to two parts sand, with a small amount of water added. This mix is essential for creating a strong bond between the logs and the mortar. When measuring the ingredients, use a bucket or container to ensure accurate proportions. A 5-gallon bucket is a good size for mixing small batches of mortar, which is ideal for cordwood projects.

Choosing the Right Sand and Lime for Your Mix

When selecting sand for your mortar mix, choose a fine-grit sand that is free from contaminants and moisture. A 20-mesh sand is a good choice, as it allows for easy compaction and a strong bond between the logs and the mortar. When it comes to lime, beginners should opt for a Type S hydrated lime, which is specifically designed for masonry applications. This type of lime is less alkaline than other types, which helps prevent damage to the logs and ensures a strong bond between the logs and the mortar.

Mixing and Applying the Mortar

To mix the mortar, use a power drill with a mixing paddle attachment to combine the ingredients in a bucket. Start by adding the dry ingredients and slowly adding water while mixing until a workable consistency is achieved. Apply the mortar to the logs using a notched trowel or a mortar float, working in small sections to prevent the mortar from drying out. For best results, apply the mortar in a thin layer, about 1/8 inch thick, and smooth it out with a trowel or float.
