Spraybond® Spraying Canister Adhesives & Primers
Cleaning and maintenance guide for Spraybond Canister Adhesives and Primers
Not all canister adhesives & primers apply the same
The spray patterns we achieve from each formulation of canister adhesive or primer varies, as each formulation differs along with the pressure within the canister itself. Even though all our product formulations are different, there are three spray methods adopted by our product line. These are web, splatter and beaded spray patterns.
There are also external factors that play a part in altering the way all products spray. The first being temperature fluctuations which are the most prominent external influence to canister adhesive and primer application.
Colder temperatures will typically reduce the pressure of the canister and the width of the spray pattern. On the other hand higher temperatures will increase pressure and the width of the spray pattern. To keep things consistent we advise storing canister at 15 – 30°C prior to use for optimal performance.
Adjustment & Preparation
The size of the spray pattern for all of our canister adhesives and primers are adjusted in the same manner on the spray gun itself. To alter the width of the spray pattern, adjust the control knob behind the guns trigger. Open it to increase the width of the spray pattern, or close it to decrease the width of the spray pattern. It’s always a good idea to test and set your spray gun on some scrap material prior to installing.
One key thing to ensure before beginning application of any spray adhesive or primer system, is to make sure you’ve pre-prepared for the installation.
Here are some key tips:
Protect all membrane seams and installed membranes from overspray or accidents during application.
Have membranes or insulation pre-cut ahead of time so once you start applying adhesive you can fly through instead of stopping and starting unnecessarily.
Take the temperature in to account, if it’s cold expect to wait longer for the adhesive to flash off or grab the insulation boards and adjust your schedule to suit.

Splatter Pattern
Spraybond Fleece-Back is our only adhesive that sprays with a splatter pattern. As the adhesive is a low foaming polyurethane, it’s a higher viscosity than our typical contact adhesives. The result is a snowflake like application to the substrate allowing for simple coat weight control.
For this application we recommend using the 600mm extended spray gun, DT-SG. When applying this adhesive keeping the gun at a distance of 200mm – 300mm from the substrate. Keep the gun moving left and right to build up an even coat, not allowing the adhesive to puddle. Coat weight will vary based on the substrate condition.
For the best performance of this adhesive always ensure it’s stored between 15 – 30°C prior to use and is shaken thoroughly for 30 seconds before each use. This ensures the best pressure profile for consistent application.

Bead Application
Spraybond Insulation Adhesive is our only bead applied adhesive. Through partially bonding in high foaming beads of adhesive, the high performance foam takes up the undulations in the roofs substrate forming a long lasting bond to the rigid insulation board.
We apply the adhesive as standard in 30 – 40mm width beads, increasing to 50mm when adhering to unfaced stone wool insulation such as Rockwool Dual Density insulation.
Our beads of adhesive are applied at different bead centres depending on there zoning on the roof in question. This is split into two zones , normal roof exposure and roof perimeter. The zoning of these areas is to be determined by performing a wind-load calculations for the project in question. For Spraybond Insulation Adhesive, the beads of adhesive are laid every 300mm and every 200mm for roof perimeters.
For the best performance of this adhesive always ensure it’s stored between 15 – 30°C prior to use and is shaken thoroughly for 30 seconds before each use. This ensures the best pressure profile for consistent application.

Cold Climate? Warm up with a blanket
As we discussed at the beginning of this article, temperature is the biggest potential external factor on how canister adhesives and primers spray and apply. If the temperatures are low in the depths of winter, look at using a Spraybond Heating Jacket to keep performance at its best. Jackets come with 110V plugs suitable for on-site use with set temperature parameters to ensure its kept at a consistent heat.
