Repairing Grout Around a Bathtub: Dremel Multi-Max

Repairing Grout Around a Bathtub The action of the Dremel Multi-Max
coupled with its uniquely shaped grout blade makes it the perfect solution for
repairing a bath surround. For this project will use the Dremel
Multi-Max oscillating tool and an MM501 one-sixteenth inch carbide
grout blade. Begin this project by inserting the
carbide grout blade into the tool. Tighten the screw with the allen
wrench to secure the blade in the holder. Set the tool to medium to high
speed then guide the blade into the grout. To protect your tub we recommend that you
apply a line of tape around the top edge of your tub first. You can also take the tile for added
protection. In smooth even motions continue to remove the grout on all
sides. Depending on the hardness of the grout a few passes may be required. If needed the blade can be easily
rotated to get in to tight quarters and be sure to unplug the tool before
changing the blade. Remember to keep the blade parallel to
the tub ledge, did not allow it to rest on the time to avoid any scratching. This also sets the blade a right angle
to the wall. With the blade in the grout and with a
smooth motion you’ll prevent any tiles from being nicked. To control plunge depth, use the carbide grit line on the blade
as an indicator do not plunge beyond the grit line as you could damage the backer board material. When you’re finished dust the area, remove the layer of tape
and wipe clean with a damp cloth. Start your line of caulk working from the
corners first. Once a smooth bead is set, wet your finger and smooth out the caulk. Let it set for the recommended time and
your bath is as good as new.

After vacuuming, if you leave the blue tape on, then caulk and smooth the line, and THEN remove the blue tape, you will have a much better looking caulk line.
