A clean Gusmer D-Gun Mix Module port is shown below. You have used your tip cleaner in conjunction with glycolic either and compressed air to remove foreign material from the block. After rinsing liberally with glycol and triggering with air you should see completely through the mix module when the trigger is held open and the D-Gun is placed towards the light right in front of your eye for proper inspection.

Cleaning the Gusmer D-Gun Brass Backing Felt is an important step when installing a new mix module. Here you can see the old one being removed or a new one being inserted. A mix module by any other name is blasphemy and usually plastic, lol.

A clean D-Gun Tip is your goal even while spraying. Be sure to carry extra Glycolic Either with you or have it handy with your helper. A wire brush or a knife also helps to maintain the spray pattern if tits develop during prolonged triggering applications. Make sure your valving rod comes out to the proper distance just barely past the main valve rod nut shown here or slightly counter-sunk depending on how you like your pattern.

Removing the D-Gun Valving Rod is a crucial step best accomplished with the air on and available to the trigger. If the rod is stuck a few good pushes on the rod assembly will extricate the stuck rod from the mixing module if lubricated liberally with glycolic either. DO NOT trigger unless you have the back of the valving rod covered.

This step will be repeated by the applicator usually twice a job or more. A clean injection port will result in a properly configured spray pattern and proper application of polyurethane spray on foam insulation. You can see the tip cleaner being inserted and removing any foreign material from the mix module. Try this with the F-Gun (F for you guessed it - Take the F'in thing back it doesn't spray foam.)

Changing the Gusmer D-Gun Felt occurs after you have removed the valving rod from the D-Gun Body. You can see the valving rod laying on the table and the nut that holds the brass and the felt in the hand. Replace the felt and install a new brass washer.

After replacing the felt packing behind the Iso and Resin ports you have to torque the retaining nut just tightly enough to ensure a smooth glide of the valving rod through the mix module. Failure to do this step properly will result in all kinds of trouble and expense.

Triggering is best described by sound. You know your applicator is working the gun properly if you hear constant steady interspaced clicks coming from your proportioner unit. A faulty trigger can cause all kinds of problems. Making sure your D-Gun Trigger is clean at the start of the foam insulation job can save you alot of problems down the road.

The use of your Gusmer D-Gun requires that you maintain your spray pattern. Deviations in your spray pattern are often the result of clogged sides. Removing the sides is also one of the first steps involved in cleaning your D-Gun.

Toady I'm interviewing an Applicator of Paint. With over 30 years of painting experience behind him, Gerry Gillanders has obtained the highest level of education any one individual in the trade can obtain. That being the Red Seal Certification in not one but two Provinces in Canada.
In these economic times it is not always the ticket to have because companies are looking to maximize their profits. So if they can obtain a journeyman painter to hire an apprentice it is well worth their staffing effort. Unfortunately they soon dismiss the journeyman in an attempt to fool the apprenticeship board.
This is the case here. I'll be calling the apprenticeship board here in Alberta and soon. This is not the way the program is designed to work. I know of one company in Edmonton that is not using a Journyman Painter to train their apprentices because he is gainfully employed at another job.
The level of experience and the qualifications of a professional tradesman can't be replicated overnight by young or old apprentices. It is a visible reality. Especially when your dealing with paint and coatings.
Some things an apprentice would make easy mistakes on would be wrong solvents and hardners added to the coatings. Catalysts as well are best properly mixed in the correct ratios. An apprentice will never know these things and niether will a company without the proper jouryneyman tradespeople on their staff.
