Expert Verdict — Reviewed by the SuperArbor Pro Desk
Primus DM is a workhorse choice when a single product must serve as both board adhesive and mesh base coat. Mix to a consistent, lump-free consistency and use clean potable water; keep mixed material within its working time and discard stiffened material rather than retempering. Match the mesh weight and finish system to the project specification for a warranty-compliant Dryvit assembly.
Cementitious products are alkaline when wet and dust is generated during mixing, so wear gloves, eye protection and a dust mask, and follow the bag safety instructions.
