Latest innovation from Norcros
Adhesives is a breakthrough solution
for tiling on to bituminous substrates
Norcros Adhesives has cracked the
problem of tiling on to bitumen and
asphalt substrates with the latest
addition to its Ultim8 family of readymixed tiling adhesives.

The company has developed Ultim8
B+ specifically to enable easy and
rapid tiling on to bitumen or asphalt
surfaces or surfaces coated with contact
adhesive residues. Up until now this has
only been possible after carrying out a
messy and tedious scabbling process
to remove all traces of the asphalt and
bitumen.
This is particularly an issue in
refurbishment projects, where it may be
desired to tile over an old bitumen or
asphalt surface. These are often found
on floors where old vinyl tiles have been
removed and on balconies, and the
complications involved can greatly add
to the difficulties of tiling in such areas.
Bitumen surfaces are also encountered
in new build, particularly in cellars,
where bitumen damp proof membranes
are often installed.
Ultim8 B+ is now by far the most
straightforward solution for tiling in
such circumstances, whether interior or
exterior.
The product operates as a system in
which the installer firstly fixes Norcros
6mm Pro Board to the bitumen or
asphalt surface using Ultim8 B+, a
procedure which requires minimal
preparation. The installer can then fix
ceramic, porcelain or natural stone tiles
to the surface of the board, using a
cement-based tile adhesive, for internal
or external use as appropriate.
“Laying new flooring over a surface
covered in bitumen residues
often causes a major headache for
contractors,” says Mandy Searle, head of
technical services at Norcros Adhesives.
“Now there's no need to spend time and
money preparing the area by removing
such awkward residues. This new
product ends all the uncertainty and is a
real breakthrough in this area.”
Ultim8 B+ is available in a 15kg tub and
shares a brand identity with the rest
of the Ultim8 range of ready-mixed
adhesives from Norcros. This range
includes Ultim8 - an acrylic-based
wall tile adhesive for fixing ceramic
tiles to a variety of substrates, suitable
for large format tiles up to 400mm
x 300mm. It has been formulated to
have high initial grab, as well as superb
non-slip characteristics to reduce the
need for support battens. It is suitable
for internal wall tiling in areas such
as kitchens, bathrooms and domestic
showers for bed depths up to 3mm. The
adhesive has a long pot life for ease of
use and minimal wastage. In normal
conditions tiles can be grouted 24 hours
after fixing.
The range also includes Norcros
Ultim8+. This is a ready mixed thin bed
wall tile adhesive for fixing ceramic
wall tiles to a variety of substrates. In
addition to its non-slip characteristics,
Ultim8+ is highly water resistant and
suitable for internal wall tiling in wet
areas such as domestic and commercial
showers including power showers.
