| BACKER
ROD:
An extruded foam rod that is typically placed in joints that
are deeper than 1/2" (12.5 mm) to fill in some of the space
before the sealant is applied. Foam backer rods come in a
variety of diameters, ranging from 1/8" (3 mm) to3/4/" (20
mm)
BINDER:
1. A component of paint that "binds" the pigment particles
into a uniform, continuous paint film, and makes the paint
adhere to the surface. The nature and amount of binder helps
determine most of the paint's performance properties - washability,
toughness, adhesion, color retention, and durability. 2. In
caulk, a component that "binds" the pigment particles into
a homogeneous compound and makes the caulk adhere to the surface.
The main performance properties of caulk - durability, adhesion,
and flexibility at low temperatures - are determined by the
binder.
BIOCIDE:
A biologically active paint and caulk additive designed to
keep bacteria from spoiling the paint or caulk during storage;
or to keep mildew from growing on the applied paint.
BLEACHING:
Loss of color, usually caused by exposure to sunlight.
BLEEDING:
The migration of material from the substrate, causing discoloration
of the paint.
BLISTERING:
The formation of dome-shaped, hollow projections of paint.
BLOCK
FILLER:
A thick, paint-like material used to smooth out very rough
masonry surfaces like cinder block. It is generally brush-applied,
then painted.
BLOCK
RESISTANCE:
The capability of a coating to resist sticking to itself when
used on two surfaces that come into contact with each other,
e.g., door and jamb; window sash and sill.
BOXING:
The mixing together of the different cans of like paint to
be used on a job, to ensure uniformity, especially of color.
BREATHE:
To allow the passage of moisture vapor from the substrate
through the paint film.
BUILD
(or FILM BUILD):
The thickness that a paint tends to be applied in, when using
the normal application technique for that paint.
BURNISHING:
The formation of shiny areas on a painted surface, as a result
of rubbing or washing.
