observation). The adhesive must be used accordingly for non-porous conditions, or
for porous conditions. The label describes both methods. Essentially, if its
porous, you can lay into it wet, if non-porous, you must let it flash-off first, the
label explains.
BR-715, an epoxy Nose-Filler is required to maintain your warranty. If there is
any void between the step nose and the Tread nose, BR-715 must be used to fill
that void. If you do not use it, you will start cracking at the nose from traffic and
flex.
To apply, spread liberally in the back of the nose enough material to fill the void.
When the Tread is pushed into place, the Nose-Filler should fill the existing void if
enough material was used. CAUTION – Do not use if the void is greater than ¼”.
If the gap is greater than ¼”, then we do not recommend our Stair Treads for that
application until the substrate is modified to allow a void of less than ¼”.
BR-101, a Cove Base adhesive that can be used on the Risers, Skirting/Stringers,
or any wall base needed for the Stairwell, if the wall is porous.
Step-Bond Tape is a 2-sided, pressure sensitive tape for installing Treads and
Risers. There is a 1” wide roll for use with the Nose, and 6” wide rolls for the step
part of the tread, and the riser if using the one-part Tread/Riser combination part.
Use 2 - 6” wide strips for Stair Treads and
3 - 6” wide strips for Tread/Riser combination parts. This product requires a very
clean substrate. We are not recommending this tape for Vinyl Tread Applications
at this time.
WARNING - ANY EXCESS ADHESIVE THAT COMES UP BETWEEN SEAMS OR
AROUND THE PERIMETER OF PARTS, MUST BE CLEANED UP IMMEDIATELY
WITH WATER OR RUBBING ALCOHOL AND A RAG. IF THAT EXCESS ADHESIVE
HARDENS ON YOUR FLOORING IT WILL BE PRACTICALLY IMPOSSIBLE TO
CLEAN OR REMOVE WITHOUT DAMAGING THE TILE OR TREADS.
Trowel Size
For most conditions, use a 1/16” X 1/16” X 1/16” Square-Notched Trowel. If your
steps are new, porous wood, or new concrete with very open pores, use a 1/8” X 1/16”
X 1/8” V-Notched Trowel.
