Post Pour Checklist

After the installation of your Firm-Fill underlayment, you are responsible for the following:

1. After the pour, maintain a 50 degree or above temperature and ventilation to dry the floor.  (Approx. 5-7 days if drying conditions are adequate).  Leave windows 2"- 4" open.  Low temperatures or high humidity will lengthen the drying time, possibly resulting in lower than average strengths.
   
   
2. Place temporary wood planking in areas subject to heavy wheeled traffic or concentrated loads.
   
   
3. DO NOT install floor coverings over FIRM-FILL until it is thoroughly dry.  Test by laying a 24" X 24" piece of plastic on the floor sealed at the edges and wait 48 hours.  Check under plastic and if floor is darker in color or water droplets are present, the gypsum floor is not adequately dry enough for floor coverings.
   
   
4. Applying latex floor sealer/floor covering primer -  Porosity of the floor is a prime factor in the drying rate of adhesives.  This porosity factor may reduce the effective adhesive open time.  An application of latex floor sealer/floor covering primer will minimize the porosity factor.  See our Sealer Application checklist .
