1-inch and shall be effected using either of the procedures given below:
a. Use a sealer having two sets of rubber coated pullwheels and opposing jaws, using 40 psi
as the upper sealing conditions;
b. Cut two sheets of Type II barrier material of the appropriate size. Cut a sheet of copier
paper to use as interleaving. Place the first sheet of material, adhesive side up, on a hard, smooth
horizontal surface. Place the interleaving sheet on top of the material to mask areas that are not
to be sealed. Place the second sheet of material, adhesive side down, so that its edges are
superimposed on the first. Roll the unmasked areas using a 2-inch wide, 1 ½-inch diameter hard
rubber roller applying no more than 40 psi pressure normal to the horizontal surface. Roll each
area forward and backward no more than 3 times.
