Surface preparation
1 . Using the
cleaning powder mixed with a little water and the cleaning
sponge, clean the surface thoroughly to remove soap and oil
residues. Pay special attention to the edges against the wall,
around faucets, outlet and overflow. It is advisable to remove
the drain outlet, clean and sand this particular area very
well. Rinse off thoroughly with warm water. Refinish this
area as well.
2. Using warm water and 120 grit waterproof abrasive paper,
sand the surface thoroughly (with special attention to edges
and areas around the faucets, outlet and overflow to remove
the shine. Sand until waterproof abrasive paper has worn
through completely.
Remove any signs of rust by sanding well with the 120 grit
waterproof paper, and if necessary, treat with a rust
neutralizer. Chips, scratches or any other damage can be
repaired using an epoxy filler or a fine grade polyester
filler which has to be completely cured before applying the
coating. Rinse with plenty of warm water, then dry thoroughly
using tissue paper to soak up excess water around the outlet,
overflow, faucets and edges against the wall.
3. When the surface and surrounding areas are completely dry,
use masking tape to mask the edges against walls (2mm above
bathtub surface) around outlets/overflows and faucets. Then
cover the faucets/overhead shower with plastic bags to prevent
water leakage.
Mixing
Note: Work in a
well-ventilated room
4. Pour all the contents of the Hardener can into the coating
can. Mix contents well with spatula scraping bottom of can.
Replace lid tightly on the coating can and turn upside down
and shake vigorously for 5 minutes. Turn can over, remove lid
and leave to stand for 5 minutes before application.
Application
5. Put on the gloves. Pour approximately 1/3 of the mixed
coating from the coating can into the paint tray. Replace lid
on can and store below 20 degrees C/68 Degrees F.
Make sure that the surface is dust-free and completely dry
before applying the coating.
Using the paintbrush, brush in areas which cannot be reached
with the roller (i.e.outlet etc.). Put the paintbrush into a
plastic bag to keep it from drying out, ready for the second
coat.
6. Fit the roller head to the roller handle and apply the
first coat with firm, even strokes. Roll as close to the edges
as possible, overlapping the brushed portions to obtain a
smooth finish. After the first coat has been applied, remove
the roller head and gloves and discard.
Allow the entire surface to dry for a minimum of 1 hour and
maximum of 2 hours at 20 degrees C/68 degrees F.
7. Fit second roller head to handle and second pair of gloves.
Using the brush and roller, apply the second coat liberally,
avoiding runs. Use up the remaining mixed coating. Do not
apply excessive pressure and do not roll repeatedly over
places where coating is starting to dry.
8. It is very
important to look very carefully at the paint on
your final coat, as this way you can prevent any runs
before they occur, giving you an outstanding finish of
which you can be proud.
9. When complete, remove the masking tape very carefully by
pulling it up and away from the surface. Leave the plastic
bags on the faucets until the surface has cured completely (48
hours minimum).
10. Once the
Tubby coating has cured for 48 hours, it is advisable to fit a
new drain/outlet with fresh plumbers putty. Carefully fit the
new drain. Do not over-tighten as this will cut the paint and
damage your refinished tub.
11. It is
advisable to use a good 100% silicone caulking to re-caulk
your tub as this lasts much longer and is more mildew
resistant.
12. Use lacquer
thinners or epoxy thinners for cleaning.
