Recommended Dosage Guidelines

Additive Type
                                Dosage Range
                                Purpose

HPMC / HEMC

0.5–2%
                                    by weight of cement

Water retention
                                        Workability
                                        Open time

RDP

2–5%
                                    by weight of cement

Adhesion
                                        Flexibility
                                        Crack resistance

Exact dosage depends on substrate, environmental conditions, and desired performance. LANDU provides technical support for formulation optimization.
