C$27.91

High Density Setting Compounds are recommended for heavy fills or when exceptional bond is necessary. Once dry the product is not sandable. It is specially formulated to harden with very little shrinkage. This enables gypsum wallboard joints to be taped and first coated with High Density, and once set, the joints can be finished with All–Purpose Compound — all in the same day.
