Tools and supplies:

Oil-base primer paint
Paintable silicone caulking
 
Porter Cable® Random Orbit Sander

This post shows the seven steps to repair a spa bath with a crawl space.


Step 1: In this job the client had a custom spa bath sitting area. Above fig.1 shows the ceramic tile around the sitting area and near the tub. 
Step 2: The bath had an access door and this picture shows the damage that needed to be repaired. Fig.2 below shows the wood frames had mold from water leaking from the top of the tub above.

Step 3: Fig.3 shows a concentration of pure 100-percent Clorox® Germicidal liquid purchased at Lowe's was applied using a plastic spray mister. The solution was allowed to saturate the wood frame. After an hour, a fan was placed in the area to dry the wood. The wood was bleached and ready for caulking. 
The mold killer of choice was Clorox placed all over mold areas

Step 4: Fig.4 shows that wearing a mask and gloves, the wood frame was sanded to remove the damaged wood. A random orbit sander with dust pick up and a hook and loop pad with a sanding disc-grit 80 was needed to sand the wood frames. Two sanding pads were used to get this job done.

Step 5: Fig.5 shows a paintable silicone caulking was added to the wooden corners, it's not pretty but the area is sealed and ready to be primed with oil-base primer paint.
Paintable silicone was used to seal all wood joins and near the wall

Step 6: Fig.6 shows the last step was to paint the wood frame with oil-base primer.

Step 7: The problem was the tub leaked from above. Fig.1 shows that the seat is tiled and fig.7 shows that the tiles were repaired in two ways. First the grout was replaced, then the silicone was applied on the sides of the seat. The last step was to use grout sealer over the entire seat. Sealing the tile and the grout prevented moisture from reaching the wood frame.

All wood supports near the maintenace door were primed and now safe.
