Hello everyone, good work... We want to coat a curtain that we made 20 cm according to the previous regulation, because we have to meet the minimum requirements. Does anyone have a suggestion on how I can do this, because I have not done a retrofit project before, I don't have much information. It has a column coat, but I haven't seen anything like that about the curtain. I mean, I've seen a lot of column reinforcement or curtain additions before, but I haven't seen curtain thickening. :roll: Thank you for the information you will give, greetings...
