Today’s Agenda - Paint

• Materials• Application• Inspection• Tips & Tricks

Audience PollWhat best represents your current markings materials mix?

– 100% Paint– 75% Paint– 50% Paint– 25% Paint– 100% Thermo / Other

Material Basics of Traffic Paint

• Most widely used material• Applied in liquid form• Spray system• Mechanical bond• Application vehicle evaporates• Solid components remain• Semi-durable marking

o Titanium Dioxide – White

o Lead or Organic – Yellow

o Alkydo Acrylic

o Calcium Carbonateo Clays

o Watero Solvents

Four Primary Components

Pigment• Color• Opacity

Binder (Resin)• Adhesive• Cohesive

Filler• Adds Body

Application Vehicle• Transports Solids• Evaporates

Paint Technical Specification Terms• Weight Per Gallon (WPG)

– More Weight = More Solids• Water = 8.3 #/gal

– More Application Vehicle = Less Weight

• Viscosity– Also referred to as Thickness– Thicker ≠ more solids– Usually achieved with filler or special

chemicals

• Total Solids %– What is left on pavement once dried

(application vehicle fully evaporates)– High solids = longer lasting paint and

better coverage

• Dry Time– Time it takes to dry to no

tracking

• Pigment %– Amount of Coloring Component– Quality and Quantity Controls

Tint, Brightness, Fade resistance, and Opacity

• Opacity %– How much of the surface does

not show through once dry– Primarily controlled by solids and

pigment– High opacity = fewer coats

needed

Waterborne vs. Oil-Based Paints

Advantages of Waterborne• Environmentally Friendlier

– Manufacturing, Application, Disposal– Low Volatile Organic Compounds– Most Lead Free

• Easier Handling– Decreased Safety Hazards– Easier Equipment Cleanup– Minimal Transportation Restrictions

• Better Overall Performance– Faster No Track Dry Time– Not as Effected by Humidity– More Durable

Disadvantages of Waterborne• Equipment

– Slightly More Wear– Larger Tip Size Required

• Appearance– Flatter Appearance– Higher Track-ability – Holds Dirt &

Debris

• Reactions– Inferior Bond Strength to HCC– Known to Crack Asphalt at High

Temperatures– Reacts to non-Stainless Steel Metals

Traffic Paint Equipment

• Air pressurizes in sealed tank

• Pressure forces paint out of tank

• Additional air at gun tip atomizes paint for a smoother application

• Durable and low-maintenance cost

Conventional Air Striping Machine

• Pump draws paint from tank

• Paint forced into universal paint gun

• Paint exits through RAC-type tip at high pressure

• Sharper lines and easy operation

Airless Striper Machine

Audience PollWhat kind of Traffic Paint Equipment does your organization currently use for your pavement marking needs?

• Conventional Air• Airless• Not currently doing paint application

Surface Preparation

Ensure surface is free of dirt, dust and other contaminants.

Remove poorly adhered existing markings or curing compound.

Verify Pavement is Free of Moisture – Rain Forecast, Sprinklers Timer, Moisture Check, etc.

Check that Ambient and Surface Temps are at 50⁰ & rising. Caution with Ambient Temps 90⁰+

Paint Application

• Thickness of 15-25 wet mils– Second application may be necessary on porous surfaces

• Drop Glass Beads Immediately Behind Gun– Must have a 55-60% embedment

• Protect the Line Until Dry to No Tracking

• Caution - Parking Lots New Asphalt and Elevated Surface Temps:– Two Thin Applications

• No Glass Beads

Tips & Tricks

Always clean out equipment at the end of the shift – it will help prevent problems the next time you are ready to paint.

Turn your paint striper gun to the outside of your back wheel for easier striping of curved lines.

Tips & Tricks

Turn airless tip to closed position during striping delays

Make sure the machine is moving when you pull the trigger to avoid paint puddles

Tips & Tricks

Glass bead quality does make a difference

For double lines, set gun cable tension so that the outer gun activates at 50% trigger pull

Tips & Tricks

Use roofing shingles to start and stop your lines, it’ll make them more even and sharper

Have tar paper or cardboard handy for tip adjustments

Tips & Tricks

Add a splash of water to the top of the paint while striping to keep the paint from scabbing.

Traffic paint dry time is speeded up with higher temperature, lower humidity, and higher wind speed.
