Wall putty, often referred to as skim coat, is a decorative and functional material designed to create a smooth, even surface by filling cracks, pores, and minor imperfections on walls. Its primary components typically include white cement, water, and a blend of performance-enhancing additives.
MIXEON specialize in providing premium-grade Cellulose Ether (HPMC) and Redispersible Polymer Powder (RDP) as essential additives in wall putty formulations. HPMC plays a critical role in improving water retention and workability, ensuring consistent application and extended open time. Meanwhile, RDP significantly boosts adhesion, flexibility, and cohesion, contributing to a long-lasting, crack-resistant finish even under varying environmental conditions.
WALL PUTTY GRADE
1.Interior Putty
Interior putty is mainly classified into three grades based on performance characteristics:
| GRADE | Key Properties | Applications | Bond Strength (Standard Conditions) | Bond Strength (After Water Immersion) |
| Y (General) | Basic leveling; no water resistance required | General indoor dry environments such as living rooms, bedrooms, etc. | > 0.30 MPa | — (not required) |
| R (Flexible) | Moderate flexibility to resist minor cracking | Interior projects with anti-crack requirements, e.g., lightweight partitions, joint areas | > 0.40 MPa | — (not required) |
| N (Water-resistant) | High water resistance, strong bond strength, stable performance in humid conditions | Wet areas like bathrooms, kitchens, basements, and places requiring high bond strength | > 0.50 MPa | > 0.30 MPa |
2.Exterior Putty
Exterior putty is classified into the following grades:
| GRADE | Key Properties | Applications | Dynamic Crack-Bridging |
| P (General) | Basic leveling for exterior walls | Ordinary exterior decoration projects | ≥ 0.04 mm |
| R (Flexible) | Good flexibility to resist minor cracking of the substrate | Exterior applications with moderate anti-crack requirements | ≥ 0.08 mm |
| T (Elastic) | High elasticity to bridge larger cracks | Exterior wall systems with high crack-resistance requirements, such as external insulation systems | ≥ 0.3 mm |
