The flooring and wall coating industry has long sought a durable seamless  no wax  flooring system. Such a system should be easy to handle in application, resilient, no wax and extra durable.

Northern Industries, Inc. has combined the established properties of water-soluble epoxy and moisture cured urethane polymers to produce the ultimate in seamless flooring and wall coating systems.

Northern Seamless flooring and wall coating are tailored to fit your flooring and wall requirements whether residential, commercial, or industrial.

This offers virtually a limitless availability of color combinations that will adapt and compliment any decor.

In addition to being a high style custom floor, Seamless by Northern never needs wax, is completely resilient, is highly resistant to most mild acids and alkalis and to scuffing and scratching.

Maintenance cost of Northern seamless flooring and wall coating is approximately half that required for other resilient floor products and wall coatings.

Northern's seamless systems never need waxing. Frequent dust mopping with a silicone treated dust mop and wet mopping with warm water and mild detergent followed by clear water rinse is sufficient. Northern seamless flooring may be rejuvenated by a periodical reglazing.
