Vinyl Magic Vinyl Membrane Coatings were developed to overcome one of the inherent deficiencies in conventional surface coatings... that is to provide film continuity in the event of existing or developing cracks in a masonry surface. EVM coatings coatings completely seal surface porosity and cracks.
Our 23 years of experience indicates that Vinyl Magic EVM coatings can be applied to virtually any dry, clean porous substrate and clean, hard surfaces. This includes concrete, masonry, stucco, plaster, sheetrock, stainless steel, steel, fiberglass and acrylic. Proper application over the proper primer insures an adhesion of 20 pounds per square inch and this level assures protection from blistering or delamination expcept in applications which require vapor transmission through the coating.l In this application, a sealer/primer - Hydrostop 3000 - is rolled on the surface (pools, water tanks, etc.) to seal pores and stop hydro static pressure and vapor transmission. This Vinyl Magic coating has a tensile strength of 1500 psi and elongates in excess of 200% at 70 degrees and remains flexible for most structural movement and eliminates the hairline cracks that develop with non-elastic coatings.
Vinyl Magic EVM coating does not support combustion: it has a flame spread rating of 23 and 0 fuel contribution when tested in accordance with ASTME-84. A 20 mil. film has a moisture vapor transmission rate of 0.20 perms. After 1,000 cycles with a Taber CS-17 wheel, the abrasion lost was 1/4 of 1 mil. thickness.
Vinyl Magic Top Coat retains its color. Pools and roofs have gone 10 years and more without discoloration. We have the records. If desired, the Vinyl Magic System may be rejuvenated at anytime by repeating the cleaning and top coat application. It makes Vinyl Magic even more effective and durable.
Vinyl Magic is easily cleaned with simple detergents. Vinyl Magic will not allow mildew or mold to grow. Vinyl Magic is un marred by most acids, alkalis, solvents, oils and even sea water. Vinyl Magic has been health approved by state department officials. Vinyl Magic has for 23 years made pools and roofs watertight. That means leakproof!
For any project requiring a flexible, vinyl coating with excellent waterproofing properties, we suggest considering the Vinyl Magic System, an exclusive vinyl membrane coating offered by Souther Vinyl Waterproofing.
The answer is that vinyls work and work well, as shown by decades of continuous, successful service on ships, bridges, locks, dams, interiors and exteriors of potable water storge tanks, and sewage and water treatment plants, as well as in numerous laboratory studies. Vinyls consistently fulfill the high performance promise and remain one of the surest bets for satisfaction in the heavy duty maintenance market.
Furthermore, unlike the new epoxy and urethane coatings, vinyl are single-package systems without mixing and pot life complications.
Finally, years after their initial application, their recoating involves none of the sweep blasting of old, hard crosslinked films often required to maintain intercoat adhesion; their inherent solvency in the same solvents from which the original films were cast allows for excellent long-term recoatability via a colvent-welding mechanism. The gloss retention and color retention of these materials is excellent over long term.
As to the larger question of why still vinyls, the coatings speak for themselves. "Vinyls have one of the broadest and msot useful ranges of properties of any coating yet developed" (2).
Southern Vinyl Waterproofing, Inc., of Bristol, TN, has adopted liquid vinyl for the pool industries and with proper preparation of the pool surface, the vinyl should give lasting service for the home owner with low maintenance and chemical costs.
