摘要

The present invention relates to a polyurea waterproofing material spray device and a coating method for making an uneven surface on a waterproof film using the same. More specifically, the present invention relates to a polyurea waterproofing material spray device capable of forming a waterproof film having an uneven surface in a convenient manner for an operator, and a coating method of making an uneven surface on the waterproof film using the same. According to the present invention, an operator does not need to lift a polyurea waterproofing material spray device over his/her shoulder to form an uneven surface on the polyurea waterproof film, and just pulls the trigger of the polyurea waterproofing material spray device once instead of several times. So, there is an advantage that the operator can form the waterproof film with the uneven surface in a more convenient way. The polyurea waterproofing material spray device further includes a fluid hose, an air hose, a fluid suction part, an air suction part, first and second injection pipes, and a valve control switch.
