Roof Types




All spreaders are gravity-fed and have disposable rollers. All parts are disposable or simple to replace. Tank Spreaders apply any pourable material such as low VOC adhesives and coatings from a tank.

How do I clean the tank?

After each use, allow the adhesive to drain out the drain hole. It is best to wipe tank walls and hole edges before the adhesive sets up. Spray all tank surfaces with silicone spray before each use to aid in removal of hardened material

How can I adjust the flow for using materials with different viscosity?

Distribution ports can be increased with a drill bit. It is best to open the holes in increments of 1/16? at a time and usually only the center most holes.

How do I know what size spreader to use?

The 14? Singlewide is best for roofs under 100 squares and in cut up areas with penetrations.

The 27? Doublewide is a good balance of maneuverability and productivity. Ususally used on projects from 50 squares to 500 squares.

The 40? Superwide Tank Spreader offers unmatched productivity. As the operator walks along a 40? (1 Meter) swath of material is applied.

Why are the wheels covered in tape?

Teflon tape on the wheels protects them from glue and coatings.

Why are there two screws at the end of the holes in the tank?

These two holes are optional. They are to be used when applying Bonding Adhesive where no running puddle is needed.

When applying coating it is helpful if the end holes are closed to allow the running puddle to diminish toward the ends of the roller.

Instructions & Guides

There have been anecdotal reports of fires on fully adhered roofs. The exact cause of these fires has not been determined, but it has been hypothesized that a static electric spark possibly caused flammable liquid to ignite. These fires reportedly have the following factors in common:

  • 1. Low relative humidity,
  • 2. Fiberglass faced polyisocyanurate insulation, and

  • 3. Flammable liquids as the fuel.

Using flammable liquids is extremely dangerous. Anyone handling and/or using them, must be properly trained to do so.

Read and comply with all product safety labels and safety manuals for products used during the roofifing process

During the roofing process, there is a potential of creating a static electric spark

Proper grounding will prevent a static electric spark and eliminate this as a cause of fire.

You must ground the BetterSpreader and/or TankSpreader during use.


To ground the BetterSpreader and/or TankSpreader you purchased:

  • 1. Attach a wire to any bolt on either side of the product and
  • 2. Attach the other end of the same wire to the steel deck or other grounded conductor such as a steel soil stack or metal roof deck. Attaching this end of the wire to a non-grounded conductor such as plastic or wooden material is no proper grounding

To avoid an electrical shock hazard, or tripping hazard, from the ground wire:

  • 1. Guide ground wire during use,
  • 2.Prevent ground wire from contacting with flammable liquid, electrical wires or equipment. Reel ground wire in, when possible.
  • 3. Ensure work crews are aware of the ground wire location at all times, and
  • 4. Prevent unauthorized people from entering the work area.


When using a flammable liquid with the Better Spreader, care should be taken to avoid creating a spark. Electric drills should not be used with flammable liquids as the motor may generate a spark. If using a flammable liquid utilize a non-sparking Beryllium/Copper Scratch Awl to open the holes in the pail.


We hope your next project is both safe and profifitable
