Loctite® PL® 500 Landscape Block Adhesive

For Concrete Retaining Blocks and Pavers

Safety Precautions

Interior applications require ventilation to the outside during application and cure. Wear gloves. Wash hands after use.

Preparation

The temperature of the adhesive, the surfaces and the working area must be between 0°F (-18°C) and 100°F (38°C). For smooth, fast, easy application during cold weather, store adhesive at room temperature (70° ± 5°F) 24 hours prior to use. Ensure surfaces to be bonded are clean, dry, structurally sound and free of dust, grease, oil or other contaminants. To increase adhesion, sand glossy surfaces to a dull finish. Pre-fit all materials prior to applying product. Cut off tip of cartridge at 45° angle to desired bead size. For exterior applications, the recommended bead size is 3/8' (9.5 mm). Puncture seal inside of nozzle.

Application

Apply a continuous zigzag bead to one surface to be bonded. Apply the adhesive at a rate so that the materials can be positioned and fastened within 10 minutes. All projects may require support until adhesive has cured. It is recommended that all foot traffic stay off of paver stones or retaining caps for at least 24 to 48 hours after installation and heavy traffic for approximately 4 to 5 days.

For Landscape Blocks:
When installing the cap onto the final course of landscape blocks, apply a 6.3 mm (¼') bead approximately 5 cm (2') in from the front and 5 cm (2') in from the back of the cap to be installed.

For Concrete Paving Stones:
Apply an 'S' shaped bead approximately 6.3 mm (¼') to 9.5 mm (3/8') in diameter to the back of the stone to be installed. If using old concrete, clean with a 20% hydrochloric acid solution.

Cleanup

Clean tools and uncured adhesive residue immediately with acetone or mineral spirits in a well-ventilated area to the outdoors. Cured adhesive may be carefully cut away with a sharp-edged tool.
