Please ensure that the substrate surface the painted glass is being fixed to is flat
and level and is not of a non porous nature (such as melamine board or similar coated materials).
These will not allow the silicon to dry out, and may cause the silicon to bleed through
the paint and cause it to discolour where applied.
We would recommend that the best surfaces for sticking glass painted splashbacks to
are plasterboard, MDF or plastered walls (although the last two should be sealed
with uni-bond or similar primer)
Before attempting to fix painted glass splashbacks to the surface required, take time
to check the surface is free of any protruding objects or rough surfaces, that might
cut through and damage the painted surface of the glass once it is fixed in place.
Once that has been checked, put small strips of plastic, rubber or cardboard packers
directly under where the glass is going to sit, this will stop any damage happening
to the edge of the glass when putting the glass into position, and while the silicon
is going off, once the glass is finally in place. Now try the glass into position without
the silicon on. If this fits ok, take the glass off and now apply the glue in the
following way.
1. Using low modular neutral cure silicon, apply the silicon in a single line about 10mm
wide and approx 100mm in from the edge and in lines about 100mm apart thereafter.
Do not apply the silicon in blobs as this will take longer for the silicon to dry and might
cause certain paint colours to fade where the blobs are located.
2. Once you have applied the silicon in strips on the back of the painted glass, position
as before on the packers and slowly push into place using an even pressure. Once this is
done, the glass should be left for at least 48 hrs, before taking out the packers that the
glass is sitting on. If you are fitting large glass panels, a mechanical fixing will also be
required. This would entail fixing something over the edge of the glass and also to the
bonded surface to hold it in position till the silicon has gone off, alternatively something
heavy can be placed against the surface of the glass to hold it in place until the silicon
has again gone off.
3. After 48 hours a silicon bead can be put around the edge of the glass to seal the edge
(not before as the silicon needs a flow of air in order to dry thoroughly).
