W&H A-Plas VS Lime
W&H A-PLAS is the modern and improved mortar additive. Many professionals in the construction industry prefer W&H A-PLAS to lime because of its many unique properties and benefits.
W&H A-PLAS | LIME | ||
Composed of high polymerisation cellulose | Composed of calcium hydroxide. | ||
When mixed with water, it raises the water molecules, retaining water required for hydration and enhances the density of mortar. | Loses water easily after being combined with cement. | ||
Improve the workability and finishes of the plaster by reducing the chance of shrinkage cracks occurring. | Produces greater shrinkage and damage to the strength of the cement. | ||
Increase the viscosity of cement. | Does offer this advantage. | ||
Increase the bond and strength of the plastered wall. | Does not offer this advantage. | ||
Slight heat is produced when mixed with water. | High heat is produced and crack marks may result on the wall. | ||
Useful in accelerating the hydration of cement. | Does not offer this advantage. | ||
Does not contain cleaning agents. | May contain cleaning agents that lighten and smoothen the slurry; cleaning agents however undermine the strength of the cement and cause hollowing in concrete columns. |
