* Patch Pump model recommended for use with products that pump more easily and in which a higher output is desired. Low-density fireproofing and self-leveling underlayments would be good choices.

** Spray Buddy model recommended for use with hard-to-pump products or extreme pumping distances or heights. It also utilizes an AFS Auto Reverse that reduces nozzle packs significantly with sandy and aggregated materials. EIFS and waterproofing coatings would fit this category.

*** This is maximum aggregate size recommended for pump. Mix design will determine how well product will pump.

**** Pumping distance may be increased or decreased significantly depending on mix design, but we believe these to be very achievable in most instances.

  • The Spray Buddy simplified the waterproofing application and increased our profitability. We went from applying concrete waterproofing by means of Spray-Hoppers — which often required a lot of ladder work — to more robust, powerful spray equipment. We also received follow-up calls to make sure we were satisfied with our purchase. I’d say without question that the HyFlex Spray Buddy was money well spent, and our guys thank us for it."
