EZ-Spray
DIRECTIONS FOR USE
Proper surface preparation is essential to the success and performance of any application. In all cases, the application surface should be clean, dry, free
from oils, and rough.
Surface Abrading/Cleaning
1. Thoroughly clean the surface with Devcon Cleaner Blend 300 (or suitable equivalent) to remove all oil, grease, and dirt.
®
2. Grit blast surface area with 8-40 mesh grit, or grind with a coarse wheel or abrasive disc pad, to create increased surface area for better adhesion
(Caution: An abrasive disc pad can only be used provided white metal is revealed). Desired profile is 3-5mil.
• NOTE: For metals exposed to seawater or other salt solutions, grit-blast and high-pressure water blast the area, then leave overnight to allow any
salts in the metal to "sweat" to the surface. Repeat blasting to "sweat out" all soluble salts. Perform chloride contamination test to determine soluble
salt content is no more than 40 ppm.
3. Clean surface again with Devcon Cleaner Blend 300 to remove all traces of oil, grease, dust, or other foreign substances from the grit blasting.
®
4. Repair surface as soon as possible to prevent any changes or surface contaminants.
Cartridge Loading and Setting of Spray Pattern
It is recommended that cartridge, component, and ambient temperature be 72-90°F when spraying. The optimum cartridge temperature for spraying is
approximately 85-90°F. Temperatures during application will affect the flow rate, spray pattern, coating surface appearance, and the maximum achievable
drip-free coating thickness.
In cold working conditions, directly heat repair area to 80-90°F prior to applying epoxy and maintain at this temperature during product cure.
Always wear appropriate Personal Protective Equipment (PPE) when dispensing product.
For the manufacturer's detailed dispenser operating instructions, visit www.sulzer.com, where you will find a Quick Reference Guide, an Operating
Instructions Manual, and application videos for the MixCoat Spray DPS 1500-01 pneumatic dispenser.
1. Confirm the dispenser has the correct plunger attached and that it is positioned properly. The top plunger face must read "3:1 Front". The arrow
indicating the "UP" direction must be correctly positioned
2. Remove outer shrink wrap from cartridge.
3. With cartridge in a vertical position, nose end up, remove retaining nut and nose plug. Angle cartridge slightly to cause air pocket on hardener side to
be positioned at the discharge port. Ensuring the discharge port is pointed away from the operator or other personnel, gently push up on the hardener
piston until the air is fully evacuated and a small amount of hardener discharges. Reinsert nose plug and retaining nut.
4. Load cartridge into dispenser until fully seated.
5. Connect main air supply. Maximum operating pressure is 100 psi (7 bar).
6. Close atomizing air (Figures 1 & 2, Item B) by setting to one
using adjustment wheel at the base of the grip.
7. Set plunger speed (Figures 1 & 2, Item A) to lowest setting
(one) using adjustment wheel at the top of the grip.
8. Remove retaining nut and nose plug. Pull trigger (Figures 1
& 2, Item C) fully until both Resin and Hardener components
are visually confirmed to flow regularly from the discharge
ports (Figure 2). If necessary, slightly increase plunger
speed setting to initiate flow. If one or both of the materials
does not flow, inspect the discharge port for blockage.
9. Attach mix-spray nozzle to cartridge and secure with
retaining nut (Figure 3).
10. Connect atomizing air line to the mix-spray nozzle tip
(Figure 4). Position the connection to the side or top of the
nozzle to limit unintended product residue accumulation
during use. [Some applicators choose to coat the
attachment module of the air line with a release agent
prior to use, and to clean it thoroughly between uses,
to prevent product accumulation and hardening.
Additionally, it is recommended to keep a spare air line
attachment at all times.]

11. Reduce the plunger speed (Figures 1 & 2, Item A)
to lowest setting.
12. Directing nozzle tip into a proper waste receptacle, pull trigger (Figures 1 & 2,
Item C) fully and increase plunger speed (Figures 1 & 2, Item A) until desired flow
rate is reached (Figure 5). The maximum setting of 8 may be desirable. The product
temperature affects the flow rate.
13. Keeping trigger fully engaged, adjust the atomizing air (Figures 1 & 2, Item B) to
achieve desired spray pattern (Figure 6).
Application Instructions
1. Pull trigger (Figures 1 & 2, Item C) fully. Initially direct the product spray away from
the component to be coated and purge (dispense as waste) a minimum of 25 grams
of product. Without releasing the trigger, direct product spray onto the component.
Following this procedure ensures that on-ratio product will be dispensed onto
the component.
2. During spray dispensing it is best to maintain uninterrupted product flow. Stop-Start
of the trigger should be minimized to reduce the possibility of off-ratio product and to
promote uniform product thickness onto the component.
3. Enact purge step again if the trigger is released and then product flow restarted at any
time during the application.
4. If a new nozzle is utilized and adjustment of the Plunger Speed and Atomizing Air is not needed, it
is only necessary to dispense as waste 10 grams of product before (without releasing the trigger)
directing spray onto the component.
5. When finished spraying, to limit drips from the spray tip, do not release the trigger completely. Rather,
release the trigger by first pausing at the first stage of trigger pull resulting in air flow only (Figure 1,
Item C, expanded view). Then release the trigger completely.
6. Press the red button (Figure 1, Item D) at base of the grip to retract the plungers. If returning to use
the cartridge in the immediate or near future, retract plungers a small amount to relieve pressure on
the system and reduce drips. If the cartridge will not be used for some time, such that the product
within the nozzle will thicken significantly, retract the plungers fully.
7. Remove atomizing air line from spray nozzle tip (Figure 4). Push out the cartridge from below while
lifting it upwards.
The cartridge can be stored in a vertical position until its next use. Upon next use, the existing nozzle
needs to be removed and discarded.
Areas of the dispenser that have product residue, especially the module where the air line attaches
to the spray tip (Figure 4), should be cleaned with isopropyl alcohol or an equivalent cleaner-solvent
before product cures.
Two coats of 15-20 mil each are recommended to limit pinholes and holidays.
The second coat should be applied when the first coat is firm yet lightly tacky (approximately 4-6 hours at
72°F). If the optimum recoat window is exceeded, the surface should be lightly abraded and wiped with a
clean cloth dampened with isopropyl alcohol or an equivalent solvent prior to applying the second coat.
If a smooth surface finish is desired, the product can be brushed or back-rolled after spray depositing onto
the component.
