HDP Finishes are premixed 100% acrylic-based finishes which are offered in five textures (Sandpebble HDP, Sandpebble Fine HDP, Quarzputz HDP, Sandblast HDP, and Lymestone HDP). Standard and custom colours in Dryvit's Pastel and Mid-base formulations are available. HDP finshes are hydrophobic; they repel water, resulting in less dirt pickup and a cleaner wall appearance.
