Powder Putty and Dry Mix Mortars Streamline On Site Finishing

The rise of thin-coat plastering systems is transforming interior finishing. Modern powder putties incorporate redispersible polymer powders and cellulose ethers to improve workability and crack resistance. Projects in high-humidity regions benefit from water-repellent variants that prevent efflorescence. A comparative study showed that machine-applied dry mix mortar achieves a surface tolerance of ±1 mm over 2 meters, eliminating the need for multiple sanding passes. Suppliers are increasingly offering customized formulations for different substrate types.
