Reply To: Build up Subfloor to Match ex. Hardwood Floor Height – Oli and Summer

Thank you so much, Joe!

We started to fill valleys of the new installed OSB underpayment with Ardex. After the first coat, we found that some spots got swelled (see the attached photos). We kept the Ardex as your video showed – not running but creamy. Is this normal? Should we just pop up those spots and patch with the 2nd coat?

Thanks! Happy Holidays!
