system setup is completed floors that can be effectively dried include hardwood plaster walls with wet door headers quarry tile marble and other surfaces that include grout which can allow moisture to penetrate beneath the surface apply special grid 78 to the wet area this is an irregular grid designed to let moisture and air travel vertically and horizontally between two sealing surfaces the one surface obviously is the hardwood and the next covering layer will be 3 4 mil plastic sheeting apply a special vacuum plate 70 on top of the grid on the top of the plate will be barbed nozzles 72 that will penetrate the plastic sheeting the perimeter will be sealed with 2 u2033 wide painter 39 s tape this type of tape is preferred as it will not harm the wood finish if sanding is to be done lesser expensive masking tape may be used the next step will be to set up blowers such as an injectidry hp 60 or 90 set on the suction side negative pressure mode next connect the tubes from the standard injectidry manifolds to the barbed nozzles 72 on the floor plates 70 when the system is set up turn on the hp drying system and the floor will be appear to be u201c shrink wrapped u201d in the preferred method of use some of the finish should be removed prior to.
