There are additional precautions to take where a screed or concrete sub floor is present. New concrete dries at a rate of 1 inch per month or 1mm per day. Although the concrete can look and feel dry to the touch, it can often still contain more moisture than the recommended amounts for hardwood flooring. The best way to check is to use a moisture meter - this will give you an instant reading and tell you whether you need to leave it to dry for longer. https://homespure.com/best-carpet-for-home-office/
