Singleton Birch Natural Hydraulic Lime NHL5 is used for building and pointing in exposed areas such as chimneys, and high gable ends where extreme weather hits as it has lower breathability qualities.
How do I mix the product? By using a drum mixer, roller pan or paddle mixer ( larger projects).
In an empty mixer, add 1 part sand, followed by 1 part lime and then 2 parts sand. Mix dry for at least 5 minutes. Gradually mix in the water until the required consistency is reached. Mix for a further twenty minutes.
