Preparation
All bases to receive FLEX W must be clean and free of grease, oil, dirt, paint, and other foreign residues. For better adhesion, particularly on dusty surfaces, priming with ACRYL PRIME is recommended. After priming, a suitable backer rod is installed prior to FLEX W application.
Mixing No mixing is required.

Application FLEX W is applied directly into the joint and smoothed over with a moist paint brush. Only the joints should be filled, not the angled bevel.

Precautions To prevent cold joints, apply coating finish in complete areas and schedule stops at naturally occurring breaks and joints. Do not apply if temperature is expected to drop below 40° F within 24 hours of application.
Drying Time Depending upon the temperature and humidity, FLEX W dries in 30 minutes to 2 hours. Total cure time takes 20 days. Wait at least 5 days before coating with finish.
Cleaning Immediately after use, rinse with water. Protect other surfaces from contact with sealant.
