Setup: Eastern Flooring Products RigidLock Waterproof Click Instruction Manual

Overview

RigidLock Waterproof Click is a floating rigid-core flooring system designed for indoor residential and light commercial-style use where a durable, water-resistant surface and realistic visual variation are desired. It is intended for installation over properly prepared subfloors and should not be used outdoors.

This product is best suited for installers and homeowners who want a click-lock floor that can be installed over several approved substrates, including concrete, plywood, tile, and certain existing resilient floors, as long as the base is sound, flat, dry, and stable.

Detailed Description

RigidLock Waterproof Click uses a tongue-and-groove style locking system that allows planks to be joined by angle-locking the short end and clicking the long side into place. The floor is meant to float rather than be fastened through the surface, so it needs room to move around the perimeter and must not be pinned down by cabinets, heavy equipment, or other fixed objects.

The installation method depends on the location and the condition of the subfloor, but the core idea is the same: prepare a level base, lay out the planks from multiple cartons to blend color and pattern variation, and maintain the required expansion space around walls, jambs, and other fixed vertical surfaces.

For tight areas such as under door jambs or counters, the groove lip may need to be trimmed so the plank can slide into place. In those cases, wood glue may be used at the modified joint, and the plank should be held until the adhesive sets.

Safety

Before removing any old flooring, check whether resilient coverings or black asphalt adhesive may contain asbestos. Dry scraping or sanding those materials can release hazardous fibers, so proper removal methods must be followed.

The floor should only be installed over a subfloor that is structurally sound and flat enough for the locking system to stay engaged. Uneven areas can stress the joints and lead to clicking failures or plank disengagement.

Protect the installation from prolonged direct sunlight, since excess heat and UV exposure can affect performance. Heating mats are not recommended directly under this type of floor, and radiant heat must stay within the stated temperature limits.

When working in a crawlspace, maintain proper moisture control and ventilation so the building structure is not exposed to avoidable mold, mildew, or movement caused by damp conditions.

Setup and Operation

Before installation

• Run HVAC so the installation area stays between 65°F and 85°F.
• Allow the flooring to acclimate to the same temperature before installation.
• Work from multiple cartons to blend pattern and color variation across the room.
• Inspect the floor for visible defects before laying planks.
• Verify the subfloor is dry, flat, level, and structurally secure.

Approved subfloors

• Concrete slab
• APA rated plywood underlayment
• Properly prepared gypsum cement
• Underlayment-grade particleboard
• OSB at minimum 3/4 inch
• Existing hardwood
• Ceramic tile
• Single-layer resilient tile and sheet vinyl

Installation steps

• Dry lay several rows first so identical planks do not sit beside each other.
• Measure the room so the final row is not reduced below half the plank width.
• Start the first row with the tongue side facing the wall and place spacers around the perimeter.
• Join the short end of the next plank at an angle, then lock the long edge into the row behind it.
• Keep end joints staggered by at least 8 inches.
• Use a scrap piece as a tapping block when closing joints with a rubber mallet.
• Use the cut-off piece from one row to start the next row when it is long enough, which reduces waste.
• Trim the final row as needed and tighten it with a pull bar.
• When the long joint cannot angle into place under a counter, trim the groove bottom, add wood glue, and slide the tongue into the mating plank.

Under door jambs and moldings

• Trim the groove lip if needed so the plank can fit under the molding.
• Test the fit with a pull bar before gluing.
• Confirm that the required expansion gap remains in place and the board is not pinched.
• Use wood glue on the modified groove area, then secure the plank with painter’s tape until dry.
• Do not use masking tape or duct tape on the finished surface.

Radiant heat guidance

• Use only embedded radiant heat systems.
• Reduce heat to no less than 65°F for three days before installation.
• Turn heat off at least 24 hours before, during, and 24 hours after installation when adhesives are involved.
• Raise temperature gradually after installation, by no more than 5°F per 24 hours.
• Keep the floor temperature at or below 85°F.

Cleaning and Maintenance

After installation, move furniture carefully using an appliance hand truck over hardboard runways. Place felt pads under furniture legs and use large, non-staining protectors under heavy items and appliances. Chairs in office areas should sit on a protective mat, and castors should be wide rather than ball-type.

Keep dirt and grit off the surface by using walk-off mats at entrances. Sweep or vacuum regularly, but avoid vacuums with beater bars unless that feature is turned off. Clean with a damp mop, clean water, and a diluted neutral-pH floor cleaner only.

Do not use abrasive cleaners, detergents, or mop-and-shine products. Oil-based products, driveway sealers, and some rubber-backed items can stain or discolor the surface, so spills should be avoided and mats should be non-staining. Because smooth floors can become slippery when wet, allow the floor to dry fully after cleaning.

Troubleshooting

• If the locking system disengages, check for subfloor unevenness and correct high or low spots before reinstalling.
• If the final row is too narrow, shift the layout by trimming the first row so the last row stays within the acceptable minimum width.
• If a plank will not fit under a jamb or counter, trim the groove lip carefully and test again before using glue.
• If gaps appear in a row, recheck expansion spacing, joint alignment, and tapping technique.
• If the floor is exposed to too much sun or excessive heat, address the condition quickly to reduce movement or surface damage.
• If the installation is over radiant heat, verify the system is embedded, the temperature stays within limits, and the heat-up schedule is gradual.

Pros & Cons

• Pros: Waterproof click-lock installation, broad subfloor compatibility, realistic pattern variation, and clear guidance for difficult areas like door jambs and counters.
• Pros: Suitable for floating-floor applications with defined expansion requirements and radiant heat instructions.
• Cons: Requires careful subfloor prep, strict expansion gaps, and temperature control.
• Cons: Not meant for outdoor use, direct sunlight exposure, or installation over heating mats placed directly beneath the floor.
