Localized gaps caused by subfloor irregularities call for disassembly of the floor to expose the subfloor. Once you have access to it, you can properly level it with leveling compound or a belt sander. Chris Deziel has a bachelor's degree in physics and a master's degree in humanities.

The Causes of Gapping Pergo recommends a 3- to 5-day acclimation period prior to installation so the boards can come into equilibrium with the humidity conditions in the installation space. When the tongue is in the groove, press down until the joint clicks into place.
Work in rows. When you are done with the first row, move to the next. It's also common practice to lay the planks in the direction that any light entering the room shines down the length of the plank. Continue the row. At a 30 degree angle along the long side of the two pieces, push the new piece into the groove. They should click together easily, or you can use a crowbar or a hammer to tap them into place gently.
Start the next row. Stagger the length of the planks in the second and following rows so that none of the planks end at the same place. The best way to do this is to cut a 2 foot 0.
Then use a full plank for the third row and keep rotating across the room. Cut your pieces in an area away from where you are installing the floor so the dust does not get into the joints. Measure from the end of the last piece, subtract a quarter inch, and measure the finished surface to that dimension. Make your cut using a mitre sliding saw. If it's not quite straight on the edges, it'll be covered by the baseboard anyway. Continue laying rows until you've filled the room.
Connect the joints of the long side of the starter piece with the groove of the last row laid. Press the plank down until it locks into place. Secure the piece into place by using a tapping block near the end of the plank and gently knocking the piece. Continue with the tapping block down the row as you place a plank.
Install the baseboard. When you've completed the rows, you're done with the Pergo installation. Install the baseboard according to your plans for the room and return any fixtures where you removed them.
Method 2. Check to make sure the concrete is level. If you're laying Pergo over concrete, remove all carpet, trim, and other things covering the sub-floor to expose the concrete underneath. Before laying Pergo, it's a good idea to smooth out the concrete to make sure that you've got the flattest surface possible for the new installation.
Use the level to make sure it's smooth, and take steps to smooth it out if necessary with new concrete. Mix a batch of concrete leveler. Uneven floors need to be smoothed out with concrete leveler.
This usually comes in a lb bag, which can be mixed with water to prepare. In a bucket, mix a small batch of concrete with water as directed. Don't mix more than you'll use in the next hour, or it'll dry out and become useless and hard. Use a putty knife or a trowel to smooth out the concrete as thinly as possible, feathering out the edges of your work as you go.
Install the vapor barrier when the concrete has dried. Wait at least 48 hours before installing a vapor barrier over the fresh concrete leveling job, then put down a vapor barrier as described previously.
These polyurethane sheets are usually available from Pergo dealers as part of the package. Cover the entire floor with the sheets, which should be cut to completely cover the floor. Make it big enough on the sides so any vapor coming up will end up behind the baseboard. Tape the seams together before continuing with installation.
Install Pergo as before. Once you've smoothed out the concrete and added the vapor barrier, installing Pergo over concrete should be exactly the same as installing over wood. Pick a corner, start clicking them together leaving the appropriate amount of space between rows, and trim them to fit on the ends. Remove just enough so that you can put in some of the undelayment.
Remove enough to do one column or row, then repeat the process. Yes, it's tedious, but any other way is messy and you may ruin some of your flooring. Not Helpful 4 Helpful 5. On concrete floors can you use polyethylene before the pergo foam vapor barrier? Yes you are supposed to. They should sell giant roles of visqueen your polyethylene at the home stores. I like 6mil but 4 is ok thinner than 6. Not Helpful 3 Helpful 5. You should not use additional underlayment.
Including an additional layer of underlayment will likely void the warranty. Not Helpful 6 Helpful You don't have to, but it's a good idea, because it's easy for spills to get though that way.
You want to seal any spots where water can get through, especially in kitchens. Not Helpful 0 Helpful 3. Not Helpful 2 Helpful 2. The underlayment provides a buffer and accounts for imperfections in the subfloor. Not Helpful 1 Helpful 2. Yes, but you will need to remove the cabinets, and then reinstall them on top of the flooring. Not Helpful 7 Helpful 6. Our laminate is curling as we install each piece of Prego flooring, making it impossible to keep adding rows.
What can we do? Curling happens when the floor isn't locking correctly. Tap your planks tighter with a tapping block it is best to do this one at at time , since your floor isn't quite locked.
This should help prevent the curling. Not Helpful 2 Helpful 1. Use a tapping block and pull bar where the block won't fit, and carefully close the gaps keeping 8" from the edge of the plank. Lock either the short end or the long edge first, then tap the other into place. The planks will flatten out as they are locked.
Lifting the long side slightly 1" will help direct the plank into place if you've locked the short end first. The edges chip easily, so make sure your block is positioned correctly.
Not Helpful 0 Helpful 1. Can I leave the baseboard on when installing over hardwood and only remove the quarter round? Yes, you can. What you have described is a base shoe or quarter round over a base board. Treat the base shoe as baseboard and leave the existing baseboard in place.
