How to achieve DM2 concrete floor.

To achieve a DM2 concrete floor using a truss screed, the following steps should be followed:

1. Prepare the subgrade: Make sure the subgrade is compact, level, and free of debris.

2. Pour the concrete: Pour the concrete to the desired thickness and level.

 

3. Strike off the concrete: Use a straightedge or screed board to strike off the surface of the concrete.

 

4. Vibrate the concrete: Use a vibrator or vibrating screed to consolidate the concrete and remove any air pockets.

 

5. Install the truss screed: Assemble the truss screed and adjust it to the desired width.
 

6. Screed the concrete: Use the truss screed to level and smooth the concrete surface. The truss screed should be pulled in a straight line along the length of the pour, making sure to apply even pressure.

7. Finish the concrete: Use a float or trowel to smooth the surface and work in any aggregate that may have been disturbed by the screeding process.

8. Curing the concrete: Allow the concrete to cure for the appropriate time, typically 7-14 days, before allowing any foot traffic or heavy machinery.

Note: The specific steps and methods used will depend on the size and complexity of the project, as well as local regulations and standards. It is always recommended to consult with a concrete contractor or engineer for the best results.
