Insulation and vapour barrier goes up and I tackle the priming and painting of the OSB walls. All the final gas line alterations are completed as well.
Priming and painting OSB is tough work but the right materials and prep can make the work and final product much better.
1. On raw OSB, it's going to push the suggested primer square footage coverage to the max. Plan to overbuy primer by 20%.
2. If you want a smooth finish once you're done painting OSB, you will need to fill and sand the surface multiple times, and/or find a primer and paint with heavy self levelling attributes.
3. OSB strands will come loose. Use any flat tool to knock off strands that are poking out. If they stick out now, they will never stay down later.
4. If you are only priming, or only planning on painting 1 coat after primer, you should do 2 coats of primer. Keep in mind 2nd coats of the same primer/paint typically only consume 60% of what the first coat used.
5. Be generous with primer application. It will naturally fill the deeper, porous holes in the OSB sheeting which will make final paint coverage more effective and it will give you a more even finish.
