Bostik Entrainit Powdered Mortar Plasticiser is a soluble organic sulphote formulated to plasticise mortar mixes by the entrainment of minute air bubbles. It improves the workability and frost protection of the mortar without the addition of lime and is suitable for use in mortars for bricklaying, plastering and rendering. Entrainit Powdered Mortar Plasticiser is particularly effective with well-graded sharp sands as these produce the best mortars but are difficult to work. Mortars containing Entrainit Powdered Mortar Plasticiser spread easily and hang well, reducing droppings. They also retain water to help produce a better bond and provide durable, watertight joints.
