Instruction Manual

After the first sealer (screed) section is positioned over the sealer guide and over the highest point, it

must be LEVELED PERFECTLY not only over its length but, across its width, as well. to achieve this,

shimming material will probably be required. Vinyl floor tile cut in strips 7/8” wide by 6” long make ideal

shimming strips that can be placed beneath the sealer, wherever necessary, to achieve levelness.

IMPORTANT: EVERY SECTION OF SEALER (SCREED) MUST BE SUPPORTED AT LEAST EVERY

24” BY EITHER THE BUILDING FLOOR OR BY SHIMMING. Avoid using shimming strips less that 6”

long whenever possible (see Figure 4)

Assuming that the first sealer (screed) section has been perfectly leveled, refer to the sealer diagram

and select an adjoining sealer section and level it perfectly in both directions, shimming wherever

necessary. NOTE: Sealer (screed) sections 8” high or more employ section latches for end-to-end

locking. CAREFULLY flush the upper edges and the inner or outer surfaces of adjoining sealer sections

while locking them together (Figure 5). Continue leveling the remainder of the sealer sections until the

entire assembly is in position.

When the entire sealer assembly is leveled, apply NSF approved sealant to achieve a vapor seal

between the bottom edge of the sealer and the building floor. This sealant is provided and is packed in

the hardware box. The sealant must be applied to the inner and outer surfaces of the sealer (screed)

assembly. Make certain that the sealant produces a complete, air-tight seal, without gaps, and that

special care is taken to seal the shimming material appropriately.

After the sealant has had an opportunity to set up, trim away all excess material flush with the edges

of the sealer (screed) assembly and touch up any areas where the sealant is not making a perfect seal

(Figure 5.).
