To string line your Pro Screed, there are a few important steps that needs to be followed.
1. Place each end of the Screed on a plank of wood or another similar type of support.
2. At approximately 1" out from the leading edge of the Screed Blade, drive a nail into the wooden support.
NOTE:- Nail should be on the outside edge of the wooden support.
3. Stretch a line as tight as possible from nail to nail. Make sure that the nail is contacting each support at the point of blade contact.
NOTE:- The support do not have to be on the same level.
4. Use a short, at piece of metal or wood as a gauge block to compare the string to the bottom surface of the Screed Blade.
5. The Blades should be equal to each other at each splice. If they are not even, loosen the Jam Nuts and tighten top pipe coupler
NOTE:- Always String Line your Screed before each pour to ensure that you get the desired atness and levelness rating.
