Installation Tips for Saniflex-Flexible Wall System

Saniflex offers significant advantage over hand lay-up, fiberglass reinforced epoxy wall systems in performance and ease of application. As with all systems it does have its own unique set of installation techniques. This information should be passed along to contractors prior to their first installation.

Roller Application

Saniflex will not hide or fill imperfections in masonry substrates. We refer to bug-holes, block joints, etc. If a smooth, pinhole free coating is required, the substrate must be addressed with block-filler or other suitable fill material. Drywall should have a Level 3 finish prior to coating application.

This system should not be attempted at substrate and air temperatures below 60 degrees F. This restriction is not related to cure. It relates to ease of application and finish appearance.

Drywall or masonry surfaces must be primed prior to application of the 3552W. Getting the proper thickness of the 3552W is not achievable on an unprimed surface. Do not apply 3552W on wet primer. The primer (3479) should be dry to the touch before proceeding to the next coat. The primer is water based and may entrap moisture that will inhibit bond.

The "A" side of 3552W is quite thick, accurate measuring and complete mixing becomes critical. Measure and pour the part "B" into the mixing container first and then add the part "A." This procedure keeps the "A" from sticking to the sides and bottom of the mixing container and aids in complete mixing. Apply the material at 10-12 mils with high quality 3/8" or 1/2" nap, phenolic core roller covers. At this coverage you empty the roller quickly. Long passes are not practical. On an 8' wall work up or down from the center on each pass. After 10-30 minutes roll again with a 1/4" nap cover to even the distribution and lessen the texture/stipple. At 10-12 mils this product will not completely hide the substrate. If you achieve total hide the product may sag. Allow for curing overnight.

Prior to application of the second coat it is not necessary to sand out any roller fuzz or drips visible in the first application. Apply the second coat in the same process and coverage as the first. Allow for curing overnight.

Apply 5 mils of the first finish coat of 3479 using a high quality, lint free 1/4 inch nap roller cover. Allow to cure until tack free.

Prior to application of the final finish of 4685W topcoat, you should now address all imperfections. To remove drips, sags, or roller fuzz, utilize a pole sander with open screens.

Apply 5 mils of the 4685W topcoat using a high quality, lint free 1/4 inch nap roller cover. Prepping the roller cover by duct tapeing and/or singeing is advised.

In a roller application this system will have a stipple texture. The degree of stipple will be a function of temperature, mil thickness and roller nap. The product will only achieve a smooth texture via spray application of all components.

In light colors, especially white, may require two coats of 4685W to fully hide the basecoat. In medium to dark colors you can hide in one 3-5 mil topcoat. The 4685W wants to roll out at 2-4 mils. It will hang at a greater (5-7 mils) thickness but it requires too much effort to be worthwhile via roller application. Use high quality covers with 1/4" nap.
