Class 2 formwork finish
Class 2 formwork finish
(OP)
Had a job here that the architect specified class 2 formwork finish. The builder is now saying the plastic reinforcement chairs are showing up through the concrete finish. any ideas on how to fix this?

At this point, there is no good fix; bagging probably will show up even more.

Where does find the definition of "Class 2" finish? It does not sound like an ACI term.

Class 2 finish should be defined in the code or standard of the place Nicam is from. In B.C., Canada, it even defines the number and maximum size of bugholes.I would be very surprised if it is not so in his area
RE: Class 2 formwork finish
A proper Class 2 finish is quite challenging for a lot of contractors more used to producing Class 3 or worse. What are the test panels like? Establishing and maintaining a standard for a high class finish is difficult without prior test panels (you did it good enough last time, why not this time). Is a Class 2 finish necessary and appropriate, per the architect's intent?
Photos make it a lot easier to judge whether your situation is acceptable or not, of course.
