In order to create smooth seams when splicing two pieces
of InstaTrim®, it is important to follow these instructions.
• InstaTrim must be at room temperature to ensure
proper adhesive bonding.
• If painting, we recommend at least two coats of paint
over InstaTrim to create a smooth professional finish.
• Push strips straight into corner. Do not stretch or pull
strips as you work.
ADDITIONAL TIPS
SPLICING TWO STRIPS
Place the end of the first strip,
adhesive side down on a flat
surface. Using a razor blade,
cut the end of the first strip at
a 45º angle. Then apply strip
to the surface.
The ends of the spliced strips will
have no adhesive.
Apply a small dab of permanent
glue to adhere the two pieces at
the seam and ensure adhesion.
Press the end of the second piece
next to the first piece, overlapping
the angled ends.
Cut the beginning of the
second strip at a 45º angle in
the opposite direction so the
two ends will overlap.
SPLICING TWO STRIPS AT A CORNER
Butt the flat end of the strip
against the adjacent wall.
Cut the end of the next strip at a
compound angle to overlap the
strip that is in place.
Overlap the beginning end of the
second strip onto the first strip.
This will leave the end of the strip
without adhesive.
Apply a small dab of permanent
glue to adhere the two pieces at
the seam and ensure adhesion.
