## Questions & Answers

**Q: does counter sunk  section go on outside.  Does it matter?**
A: The countersink is for the screwhead to fit in so it finishes flush with the washer. Yes it does matter that you fix these the correct way; if they are fitted incorrectly the screw will be proud of the board you are installing. If this is a tile board then you won't be able to seal the boarded properly nor will you have a flat surface to tile on.

**Q: It says to seal surface so the wet plaster doesn't cause the disc to rust. What is suggested to seal ?**
A: Some tiles need to be sealed once installed, if water can't be absorbed through then the washer and screw will not rust.
Tile sealers are sold in many places.

**Q: What size and type of screw is needed and do you supply?**
A: The screw I am using are going through the center hole, which is 6.8mm, so buy something bigger
