Floors

I estimate we've worked on about 1/15th of the total surface, which should take 12 person hours, and $100 in consumable materials.

I estimate to do the entire floor would take 180 person/hours and cost no more than $2000. ($1,800 in materials and $200 in rentals)

Lessons learned:

• we applied putty at least 2x as much as needed. Should have mopped clean later
• rotary sander is a difficult beast, should have stuck with the drum sander
• these shop vacs suck balls. The rental one was the best.

labor accomplished:

• 2 person hours vacuuming/digging up cracks
• 2 person hours sanding/vacuuming (40 grit)
• 3 person hours filling with putty
• (24 hour delay)
• 2 person hours sanding/vacuuming (60 and 80 grit)

labor estimated:

• 1 person/hour applying sealant
• (2-3 hour delay)
• 0.5 person/hour applying bottom finish coat
• (2-3 hour delay)
• 0.5 person/hour abraiding with rough sponge
• 1 person/hour applying top finish coat

tools needed:

• drum sander (rental, $95 for the weekend)
• shopvac (rental, $30 for the weekend)
• sponge mop
• trowels

materials needed:

• putty $70 for a 3.5 gal, used $20 of it
• belts .5 $10 40 grit, same for 60 and 80
