PermaDri Spray Demonstration Training

Fresno Facility Spray DemonstrationsPlus Field Application Pictures

Set Up Information Facing spray machine open A and B regulator located

on pump by turning plastic gray lever handle ½ turn from left to right.

Allow pressure to build in regulator.

Use the red line on regulator gauge to determine pressure setting.

Adjust pressure setting on regulator by turning the gray knob on regulator left (up) or right (down) to adjust pressure higher or lower to desired setting.

Start Up Start Spray Machine and let material circulate. Make sure

both A and B sides are mixed well before spraying.

Spray Pattern

Take spray gun and in a container spray A side only to make sure you have a good spray fan and do same with B side.

Then spray both A and B side simultaneously making sure that both the A and B side spray fans come together approximately 12-18 inches from end of spray wand tips.

Turning plastic gray lever on regulator ½ turn from left to right

Take spray gun and in a container spray A side only to make sure you have a good spray fan and repeat with B side.

Spray into Trash Barrel to check spray pattern: Spray both A and B sides simultaneously to check “spray fan”

Spray Application Practise

Beginning at the lowest point of substrate, start spraying substrate by leading with the A side (emulsion) followed by the B side (calcium chloride) going from right to left covering the desired area and immediately spraying directly back over applied material from left to right to starting point.

Wands must be perpendicular to substrate

Feathering at end of spray pattern to avoid ridges in applied membrane

50% overlap-leading with A side followed by B side from right to left

Immediately spraying directly back over applied material from left to right

Spray application “WRONG “Too much angle to the Spray pattern

“Good” Spray Angle 90 Degrees/Perpendicular to the substrate

Good angle and excellent 50% overlap

Building Coverage Start next pass by moving spray gun towards

applicator ½ the width of applied material (point wands at the closest edge of applied material) and start covering 50% of applied material and 50% of substrate leading with A side followed by the B side going from right to left the complete distance of the applied material and immediately spraying directly back over applied material from left to right to starting point.

Spraying workable size areas

Good distance from substrate

Wands vertical to substrate

Comfortable working distance from body

Draping hose over shoulder takes weight off arm and wrist

Good spray pattern-observe lines

Immediate walk-ability-however it leaves footprints for first 30 minutes or so at 20C or 70F

Building thickness on vertical substrate

Over 2 inches in thickness ( Note: Do not spray this thick on a project!) w/o any sag

Dust mask and goggles

Reviewing thickness

2 prong moisture meter

Checking Thickness 60 – 80 mils for corrosion, wear and impact
