INSTALLATION GUIDE
STEP 1 CLEAN YOUR SUBFLOOR
The surface of the subfloor must be clean. Using your broom or vacuum cleaner, clean your subfloor from all loose debris and dirt before moving forward with the foam underlayment installation.
STEP 2 INSPECT YOUR SUB-FLOOR
After your subfloor is nice and clean it is time for an inspection. It is a very important task that’s very often neglected. Make sure to carefully inspect your subfloor and make sure it’s flat, in good repair, and dry.
STEP 3 FIX YOUR SUBFLOOR
If you noticed any issues with your subfloor, take time to address it before moving forward. Your subfloor MUST be FLAT. Period! To fix uneven subfloors, nail down all sticking out nails, repair or replace damaged wood subfloor and fill excessive gaps in the subfloor. Your subfloor plays a very important role in supporting your floor, so make sure to address all the issues now.
Keep few tips in mind before moving forward with the installation:
- Your subfloor must be flat
- Your subfloor must be dry — maximum acceptable moisture reading for wood subfloors is 14%
- Creaking areas must be repaired before installation
- If your subfloor sags, inspect the joints below for twists or weaknesses
- Capped or uneven areas on joints may be related to moisture damage
- Low areas must be replaced or filled with leveling formula
- Picked joints must be sanded
- Any sticking nails or screws must be removed or fixed
STEP 4 LET’S GET ROLLING
Unroll the underlayment.
STEP 5 TAPE ROWS
Secure rows by taping them together, this will keep your underlayment in place.
STEP 6 DON’T OVERLAP
Be sure not to overlap the pieces of the underlayment when you add consecutive rows. All you have to do is butt rows together and secure them with duck tape or flooring tape.
STEP 7 WORK BY SECTIONS
Work section by section, installing your underlayment and flooring together as you move forward. This will prevent your underlayment from moving or shifting when you install your flooring.
STEP 8 COMPLETE
Continue until your project is finished.
