517004 Sika Underlayment Self-Leveling 50lb

Description

Overview

517004 Sika Underlayment Self-Leveling (517004) is designed for interior floor preparation, providing a self-smoothing, rapid-setting surface prior to the application of final floor finishes on concrete and cementitious substrates.

Technical Features

• One-component, polymer-modified formula simplifies mixing and application while delivering a durable, modified-cement underlayment without multi-part mixing on site.
• Self-smoothing, self-leveling action the compound flows to a flat plane under gravity, reducing labor required to achieve a level substrate.
• Rapid setting: walkable after 23 hours at 73F minimizes site downtime and allows subsequent trades to access the floor surface quickly.
• Application thickness range of 1/25 in. to 2 in. neat accommodates both fine-tolerance topping applications and deeper fill work in a single product.
• Zero VOC content and low odor supports use in occupied or poorly ventilated interior environments without air quality concerns.
• Compatible with manual and pump application allows scalability from small residential pours to larger commercial floor projects.
• Suitable for overcoating with non-moisture-sensitive tile after 23 hours enables fast-track tile installation schedules.
• Floor coverings (carpet, vinyl, PVC, rubber, engineered wood flooring) can be installed after 13 days provides clear re-coat and installation windows for project scheduling.

Applications

• Renovation of old interior concrete and cementitious floors requiring leveling prior to finish floor installation.
• Preparation of new concrete slabs to achieve a flat, smooth surface before applying carpet, vinyl, PVC, rubber, or engineered wood flooring.
• Fast-track tile installation projects requiring a level substrate within 23 hours of pour.
• Interior concrete and cementitious substrates where a low-odor, zero-VOC compound is required.
