PROMAFOUR® (continued)
Painting PROMAFOUR®
4
If required PROMAFOUR® can be painted
with specialist high temperature paint, such as
Keim Paint. Please refer to paint manufacturer
guidelines.
TIP
We have only discussed a paint finish but if you
prefer a tiled finished, install with rough side facing
the room and prime the rough surface and fix tiles to
PROMAFOUR® using PROMAFOUR® glue.
PROMAFOUR® can be tiled with a minimum
board thickness of 12mm. The boards should
be sealed on both faces with PVA or watered
down tile adhesive and allowed to dry.
The boards should be fixed with the textured
face outwards, to the supports at 200mm centres.
The screws should be countersunk and corrosion
resistant. The tile should then be fixed using
Promafour
®
Glue.
Maximum tile weight: 30kg/m2
Allow 24 hours for the fire place to dry before
lighting the stove for the first time.
TIP
PROMAFOUR® needs to be gently warmed up.
If the fire becomes over heated by turning too much
wood in one go, this may damage not only your
appliance but may also cause cracks to appear in the
boards at first heating, as all refractory material will
shrink and expand at high temperature and therefore
need time to be settled. Therefore we recommend at the
beginning to heat up slowly to the required maximum
temperature, by burning at a low primary air level and
not too much wood in one go. High moisture content
can lead to cracking if heated up too quickly.
Allow 24 hours for the paint to dry.
