CHEMISTRY
What’s really in a PAINT CAN?
Essentially, a paint consists
of a PIGMENT, dispersed
in a BINDER , and reduced
with SOLVENT as transfer
medium.

One or more ADDITIVES

may be incorporated to
modify the paint film’s
properties.

@boysenpaintsphilippines
Paint Components
PIGMENTS
imparts color and hiding properties

Primary Pigments
(e.g. Titanium Dioxide)
•
provides color and opacity
•
organic/inorganic

Secondary Pigments
(e.g. CaCO3, talc, silica, clay)
•
fillers or extenders
•
gives bulk at low cost

@boysenpaintsphilippines
Paint Components
BINDER
forms the paint film and
provides adhesion onto the substrate

Alkyd
•
for wood and metal substrates
•
dries by oxidation
Thermoplastic Acrylic
•
for concrete, wood, and metal
substrates
•
dries by solvent evaporation
Latex/Emulsion
•
for concrete substrates
•
dries by coalescence

@boysenpaintsphilippines
Paint Components
SOLVENT
provides ease of application
and controls viscosity of the paint
•
liquid component that
evaporates as the paint
dries
•
also provides good flow
and level during paint
application
•
can be either water-based
or solvent-based
(petroleum)

@boysenpaintsphilippines
Paint Components
ADDITIVES
enhances paint properties

Examples of Additives:
•
driers
•
defoamers
•
preservatives
•
dispersant

@boysenpaintsphilippines
Paint Classification

Water-based – coalescence
Solvent Acrylic – hybrid
Alkyd-based – oxidation
Lacquer – solvent evaporation
Epoxy & Polyurethane – cross-
linking

@boysenpaintsphilippines
 New Masonry
✓Let dry for 14 to 28 days before painting.
✓Apply concrete neutralizer.
✓Let dry overnight.
✓Sand surface to remove white crystals and
other contaminants adhering to the surface.

@boysenpaintsphilippines
 Skimcoat Plastering
✓Interior or Exterior use
✓Curing Time
✓Paint Compatibility
✓Required Preparation

@boysenpaintsphilippines
 Repainting
✓Remove loose, blistering and scaling paint.
✓Treat any mold or fungi infection using a
fungicidal wash solution or household bleach
solution (1:3 with water).
✓Check paint compatibility.
✓For chalking old latex paint, use surface
conditioner.

@boysenpaintsphilippines
WOOD
✓Only use kiln dried wood.
✓Seal stained wood.
✓Sand rough wood until smooth.
✓Countersink nail heads for putty
application.
✓Dust off surfaces and wipe with a
clean rag.

@boysenpaintsphilippines
 NEW METAL
✓Wipe surface with rag
soaked in paint thinner
✓Etch the surface with rust
converter
✓For hard to adhere
surfaces (i.e., new G.I.,
aluminum and stainless
steel): use special primer

@boysenpaintsphilippines
 RUSTED STEEL
✓Scrape rust by wire
brushing and then sand
thoroughly.
✓Apply rust converter on
stubborn rust only.
✓Let stay for about 10 to 15
minutes.
✓Wash thoroughly with clean
water.
✓Solvent wipe using
thinners.
✓Let dry then immediately
@boysenpaintsphilippines
apply primer.

Painting System
1. Primer/Sealer – intercoat
adhesion/bonding,
hiding/opacity (e.g. colored
primers)
2. Putty/Filler (optional) –
full/spot putty, minor surface
imperfections
3. Texture (optional)
4. Topcoat – 2 to 3 coats (in-
between layer =
intermediate coat), color,
sheen, finish
