The trowel method is a hand-applied application generally used mini drill press for thin lining (i.e. ladle tops at the pour areas). the amount of water will vary with the type of refractory and must be just enough for the material to be sticky and stay press in place. an important thing to pay attention to when troweling is to avoid over troweling the finished surface. this will bench bring cement to the surface and have the effect of sealing the hand drill press refractory, thus restricting the escape of water vapor, which occurs during dry out. sealed-in moisture can turn to steam during dry out and explode the lining.
