Method 1 PVA Mixed with Tetrion Powder filler
·
Rake out crack. Use edge of scraper or even a
flat ended screw driver
·
Remove debris. Flatten the edge of crack with
scraper and/or abrasive paper so that the edge is at the same level as the
existing substrate. (Wall or Ceiling).
·
Dust out crack:
·
Mix PVA with water (50 – 50) in jug or similar.
·
Place powder filler in a dry plastic mixing
bowl.
·
Slowly add the pva/water mix to a thick creamy
consistency: (Mixing with a Flexible filling knife.
·
With a small brush, apply some of the remaining
pva mix into the crack:
·
This is to seal any dust in: However, you
must wipe away any surplus pva from the surrounding area – eg ONLY apply the pva liquid inside
the crack.
·
Apply FIRST
filling: (Bonding)
·
Apply the filling into the crack with a 2.5``
filling knife – along the crack: Then, run the knife back along the crack to
remove surplus filler. *Repeat if required!
·
Then, with a clean damp sponge remove all
trace of filler from the surrounding area of the crack while still wet. If you allow the surplus filler to dry, it
will be extremely difficult to rub down or remove. *The purpose at this stage
is to fill the crack only*
·
Allow the filler to dry overnight. **The filler
will sink. ***This ok

Apply
SECOND Filling (Decorative)
·
For this filling DO NOT USE PVA
·
Mix powder filler and water to a creamy
consistency. Apply as before – into crack then, run knife back to remove
surplus.

You can leave slightly proud. Allow to dry.
·
When dry, rub down with 120g or 100g finishing
paper to a smooth edge and dust off.
·
Repeat with all similar cracks.
Method 2 Two pack filler.
As above: However, this will be harder to
work with.
Remember, the more
you `overfill` the more you have to remove.
