Apla-Tech, Inc. the makers of innovative drywall tools have added to it’s manufactured products available by entering the EIFS industry. Changes in that industry have increased the application of air & water resistant barriers liquid products that up until now were mostly troweled or rolled on by hand. We have designed a (WRB - weather resistant barrier) spray pump that saves tremendously on labor costs and satifies the archtectural requirements for that product’s application. You can watch the pump in action on you tube by going to www.youtube.com/watch?v=jCQW_eGDqRg. Senergy is coming to the market with a new product - I think it will be called Senershield MB (moisture barrier) that also can be sprayed. There are two pumps we offer the WRB 10-gallon and WRB 15-gallon. With both well under $2000 they are efficient pumps well worth the price.
