The invention relates to an air-powered manual vibrating screed which, by means of a profile (1) internally incorporating a series of pneumatic vibrators (2) interconnected to one another by means of flexible tubes (3) through which the compressed air circulates, which compressed air enters through the connection coupling to an air compressor (4), allows smoothing the plaster and the mortar in walls and ceilings in a very effective manner by the action of the vibration of the material by means of said profile (1). The invention has a particular application in the field of construction in which, due to the circumstances, it is necessary to have an air-powered manual vibrating screed, to improve the efficacy in the application of the plaster and mortar paste in plastering walls and ceilings. |
