C. Sanding
No sanding is needed on the back of stair treads. They are already sanded. The
only sanding that is required is on the front surface of the rubber riser in cases
when the stair tread lip overlaps and is adhered to the rubber riser, with either
Insta-Step™ Tape or Tread Adhesive. When dry fitting, scribe the overlapping stair
tread nose to the rubber riser while dry fitting. Then sand the rubber riser to the
scribed line for proper adhesion.
D. BR 711 Stair Tread Adhesive. BR 711 is for tread and riser only. Use BR
721 or BR 725 for tile on landings. BR 711 is a solvent-free, non-flammable
synthetic polymer-based adhesive, applied to one surface. Apply BR 711 to
the step or riser surface only. DO NOT apply adhesive to the back of the
stair tread or riser. Allow adhesive to dry a minimum of 10-15 minutes.
Adhesive should transfer to finger when touched prior to installation. DO
NOT allow adhesive to dry completely before installing the treads or risers.
Drying time will vary, depending on the atmospheric conditions. Install
treads or risers into the adhesive and roll immediately with a hand roller to
insure proper transfer to the backs of treads and risers. DO NOT allow foot
traffic for a minimum of 12 hours. Clean any excess adhesive from treads or
risers surfaces with a cloth dampened with water. Tools may be cleaned
with water while adhesive is still wet.
1. Application: Set the stair tread into its proper position on the step,
beginning at the nosing and pushing back firmly and as tightly as possible,
holding up the back surface of the tread. After the nosing is completely
fitted into place, the tread should be pushed down firmly onto the step.
After the stair tread is mated to the step, be sure to use a hand roller on
the stair tread lip to adhere it well and to remove any waviness in the
stair tread lip. After installation is completed, roll the newly installed stair
treads and nosing with a hand roller, making certain that the stair tread
nosing is fitted tightly against the step nosing.
2. Roll the laid treads with hand roller, diagonally, slowly in two directions.
This should be done immediately and thoroughly after laying, as this is the
only mechanical means to join the two surfaces.
3. Sweep upon completion of laying to detect adhesive spills. Remove spills
with warm water. Do not use turpentine (see Section I of Maintenance
instructions).
