Achieving EN 1308 Anti-Slip <0.5N/mm² with HPMC in Tile Adhesives

コメントする / Drymix Mortar、HPMC / By

Introduction Tile slippage during and after installation is a costly issue in construction, often leading to project delays, rework, and safety risks. Ensuring strong adhesion, particularly on vertical surfaces, is critical to meeting industry standards. HPMC (Hydroxypropyl Methylcellulose) offers an effective solution by enhancing cohesion, adhesive structuration, and water retention, ensuring tile adhesives meet the EN 1308 standard for slip resistance with performance below 0.5N/mm². HPMC delivers anti-slip performance below 0.5N/mm² in tile adhesive by enhancing cohesion between the tile and adhesive, structuring the adhesive matrix for better grip, and retaining water for optimal curing. Its unique properties align with EN 1308 standards, ensuring tiles stay securely in place on …

Screed vs. Self-Leveling Compound: 4 Key Differences You Need to Know

コメントする / Drymix Mortar、HPMC / By

Introduction When it comes to flooring, choosing between screed and self-leveling compound can be confusing. Both are used to create smooth, level surfaces, but they differ in application method, thickness, drying time, and suitable projects. Understanding these differences is crucial for selecting the right material for your flooring needs. What’s the Difference Between Screed and Self-Leveling Compound? Screed is a manually applied layer of sand, cement, or other aggregates that provides a durable, even surface while a self-leveling compound is a liquid material that automatically spreads out and levels itself. The screed is thicker and more suitable for large areas, whereas the self-leveling compound is thinner and ideal for fast, precise …
