Preparation
Proper storage, acclimation, tools, and inspection set up a clean floating install. Read these points before opening cartons.
Store and transport laminate flooring on a flat surface to prevent warping. Do not leave floors in areas of extreme temperature or moist rooms. Never store boxes upright. Do not stack pallets more than three high, and keep boxes clear of forklifts, trucks, or other traffic.
HydroLock Laminate is designed for indoor, climate-controlled floating installations. Acclimate to the installation room at 65–85°F (relative humidity should not exceed 65%) for 48 hours before installation. Keep this temperature maintained during and after installation. Do not open boxes until the time of installation.
Utility knife, tape measure, safety goggles, spacers, chalk line, tapping block, circular saw, gloves, pencils, speed square, underlayment, pull bar, and a moisture test/reader.
The installer’s responsibility is to visually inspect all planks before and throughout installation in a well-lit area. Defective planks should not be used. Inspect materials for color, finish, and wear layer. HydroLock cannot assume responsibility for suitability for each individual’s installation because it has no control over proper application. If an individual plank is doubtful as to appearance or dimension, do not use that piece. Complaints about visual defects are accepted only before installation with a submitted claim. HydroLock provides replacement material in a timely fashion and does not cover repair labor or claims when a visual defect has already been installed.
Foundation
The quality of your subfloor significantly affects installation results. Ensure the subfloor is dry, flat, stable, clean, and free from debris, grease, and chemicals. Laminate planks can camouflage minor imperfections — unevenness or major imperfections may telegraph through the planks and must be corrected. All subfloors must be free of deflection; variations should not exceed 1/8" in 6'.
You may install laminate over many existing floor coverings if they are firmly fixed, level, and stable. Installation over carpet, needle felt, cushion vinyl, floating floors, damaged floors, and soft floors is not recommended and will void your warranty.
Moisture content of the wood floor should not exceed 12%. Ensure the subfloor is dry, structurally sound, clean, and level. Be sure the wood is free from mold and insects.
Moisture from new or old concrete can create high moisture vapor emissions, hydrostatic pressure, and high alkalinity — a corrosive combination that damages floors over time. Perform calcium chloride and pH tests before installation; measure and record findings. New concrete must be cured for at least 60 days before installation.
Installation over radiant heat is acceptable if the system surface temperature does not exceed 82°F. The system must be operational for a minimum of 2 weeks before installation (an in-floor thermostat is recommended). Before installation, operate newly constructed systems at maximum capacity to force residual moisture from the cementitious topping, then set the thermostat to a comfortable room temperature. At installation, the floor’s temperature may not exceed 64°F; wait at least 24 hours, then gradually increase temperature (max 5°F per day). Throughout the floor’s life, maximum floor surface temperature is 82°F; increase or decrease settings by no more than 5°F per day so the laminate can adapt. During heating seasons, minor gapping is normal — humidity control and a humidifier help minimize this. Use a transition profile to separate rooms with and without radiant heat, or rooms with different temperature controllers.
Planning
Measure before installing underlayment and floor. Additional expansion joints are required if a single room has a length or width greater than 23 ft. Provide greater than 5/16" expansion at all fixed vertical surfaces. Exercise extra caution when transitioning from a larger area to a smaller area. Maintain adequate expansion in doorways with T-moldings and by undercutting door frames.
HydroLock recommends leaving an expansion gap between the perimeter walls and any adjacent hardwood floor. Expansion of 5/16" should be maintained around the room perimeter and when using transition moldings. Expansion should equal the thickness of the product.
This flooring replicates a natural product with natural color variation. For the best visual effect, shuffle planks or tiles from several cartons and do not install similar planks next to one another.
Agree with the client on which direction the floorboards should run — this influences the visual size ratio of the space. Installation parallel to the longest wall or the primary light source is recommended for best visual effects.
End joints of planks in two successive rows should never be in line; stagger them by at least 8 inches.
Make cuts using a circular saw or reciprocating jigsaw. When using a handsaw, cut on the decorative surface. With a jig or circular saw, cut with the decorative side down to avoid chipping.
Installation
Follow these numbered steps for a floating HydroLock click-lock install. Maintain expansion gaps and keep seams tight throughout.
All flooring installations require underlayment. Run the foam underlay in the same direction as the laminate panels. Butt underlay side by side with no overlap. Tape seams together.
Remove the tongue on the side of the panels that face the wall so the decorative surface sits well under the finished trim. Use a utility knife to score through the tongue several times until it easily snaps off.
Start in a corner by placing the first panel with its trimmed side facing the wall. Use spacers along each wall to maintain an expansion space of 8–12 mm (5/16" or 3/8") between the wall and the flooring, depending on the thickness of your floor.
To attach your second panel, insert the end tongue of the board into the end groove of the first panel at a 45° angle. Lower the panel flat to the floor and line up the edges carefully.
Continue connecting the first row until you reach the last full panel. Fit the last board by rotating the panel 180° with the pattern side upward, place beside the row, mark, and saw off the excess. Attach as described above.
When using a handsaw, cut on the decorative surface. If you use a jig or circular saw, cut with the decorative side down to avoid chipping.
Begin the next row with the off-cut piece from the previous row to stagger the pattern. Pieces should be a minimum of 20 cm (8") long, and joint offset should be at least 40 cm (16").
To start your second row, push the side tongue of the panel into the side groove of the very first panel at about 45°. When lowered, the plank will click into place.
Attach the second panel of the next row on the long side as described above. Push this panel as close as possible to the previous row. To attach this second board to the last board, tap the end using a tapping block and a rubber mallet. Continue along in the same fashion.
To fit the last row, lay a panel on top of the previous row. With the tongue to the wall, lay another panel upside down on this one to be measured and use it as a ruler. Don’t forget to allow room for spacers. Cut the panel and attach it into position.
Door frames and heating vents also require expansion room. First cut the board to the correct length, then place the cut board next to its actual position and use a ruler to measure the areas to be cut out and mark them. Cut out the marked points, allowing the necessary expansion distance on each side.
You can trim door frames by turning a panel upside down and using a handsaw to cut away the necessary height so that the panels slide easily under the frames.
Remove spacers — you are ready to install finishing molding.
Install the appropriate reducers, T-moldings, stair noses, quarter rounds, and end moldings for your transitions. When nailing, first pre-drill holes and never nail into the flooring. When gluing, allow the adhesive to fully cure before allowing foot traffic.
Transitions
When nailing, first pre-drill holes and never nail into the flooring. When gluing, allow the adhesive to fully cure before allowing foot traffic.
Used to finish flooring when the adjoining surface is lower than the laminate or when flooring meets carpet. Position the U-track between each edge of the flooring. Screw, nail, or glue down the track directly to the subfloor, then insert the reducing strip into the track.
Used to finish flooring when two level surfaces meet in doorways or for expansion joints. Install the same as a reducer. Expansion joints use T-molding and can be positioned in an inconspicuous place.
Used to finish flooring on landings or stair edges. Moldings need to be glued and screwed down into the subfloor for safety and stability. Use colorfill to cover countersunk screws.
Used to finish the perimeter of the room. Install quarter round using finishing nails. Quarter round molding is nailed directly into the baseboard — never into the laminate.
Provides a smooth transition from laminate flooring to carpeting or tile and at exterior doorways and hearths. When transitioning to carpet, leave a 1" space between the finished floor and the front edge of the carpet. Install the molding track by gluing or nailing it ¼" from the edge of the flooring. Push the molding into the track working from left to right. Finish the carpet by tucking it between the molding and the tack strip.
Moisture
When installing in kitchens, laundry rooms, or other areas where moisture or leaks may become an issue, the room must have a 100% sealed perimeter.
Manufacturer caution
Laminate installation in bathrooms voids the HydroLock warranty. Bathroom installs are not recommended by the manufacturer.
Expansion gaps at all vertical surfaces such as walls, cabinets, etc. must be filled with high-quality silicone caulk.
Remove the toilet and fit flooring to within 5/16" of the toilet flange. Fill this expansion gap with high-quality silicone caulk.
Install quarter round moldings directly into the wet silicone caulk. Install T-molding and wall base over the silicone caulk-filled expansion gaps. Nail wall base directly into the wall, not into the laminate flooring. In areas where a square-edge profile cannot be installed, fill the 5/16" expansion gap with silicone caulk.
Maintenance
Although HydroLock planks are inherently tough, they can be accidentally chipped by falling objects. If damage occurs after installation:
The traditional method of single-plank replacement can also be used with HydroLock Laminate. Saving extra planks from your original project makes future repairs much easier.
