But confused by the spec sheet, says you can go over osb board with this gypsum screed.... So how about backer boards? It says it can be used on gypsum fibre boards.. 1st day back today, 13hrs on my knees!
Gypsum goes over everything. It’s super low stress. Things to watch out for..it does not like moisture. If it goes over 5mm it takes ages to truly dry. Sent from my iPhone using Tapatalk
Also not great with wood flooring or LVT on HT adhesive or rubber or any other floor covering that likes to move or is moisture sensitive. Drying time is 1mm per day after 3mm. I only know that because I put down a kitchen 12mm deep and then realised the drying time the next day lol. In the right area it’s brilliant tho. Flows out amazing Sent from my iPhone using Tapatalk
