Smith Paints - Hi-Wear 90S

Apply approximately 3 mils or less (534 to 650 sq.ft. per mixed gallon) to achieve the most monolithic appearance. When exceeding 4 mils WFT, foaming and/or a blotchy appearance should be expected if applied too heavy.

Add entire contents of Part B into Part A container; including optional Smith’s ISC Industrial Solid Colorant Packs, mixing with a slow speed drill (300 to 450 RPM) with a paint mixing paddle for 1 minute. Then slowly add in the Part C powder while continuing to mix for an additional 3 minutes to ensure no powder clumps remain.

Avoid whipping air into the mixture as bubbles will occur in the finished coating & under mixing may leave lumps in the finish or lessen the coating properties.

CSP 2 to 5 (Concrete Surface Profile in accordance with ICRI Guideline 310.2R2013, as published by the International Concrete Repair Institute) on concrete to yield an absorbent substrate. Extent of concrete surface profile (CSP) necessary will be determined based on the total thickness of the floor coating system being applied while considering the type & extent of traffic anticipated. Please refer to the individual system application guide or contact Smith Paint Products for recommendations. As a rule of thumb, thicker coating systems require a more extensive surface profile / texture than a thin system.

If a densifier or dissipative curing compound is believed to have been present, see “Silicate Contamination” section on the left column of this page for treatment using Smith’s Green Clean Pro after mechanical preparation.

Smith’s Hi-Wear 90S is strictly a finish topcoat product intended as a very thin film of 3 mils in a single layer which foams when applied too thick. Any imperfections, sanding marks/swirls, scratches, gouges, etc. that can be felt by hand or catch a fingernail when pulled across the area in the prior layer may transfer through this finish due to the minimal thickness of Smith’s Hi-Wear 90S in a single coat application. Minor surface defects are purely aesthetic which pose no threat to the longterm performance of the coating system.

Once mixed, immediately pour Smith’s Hi-Wear 90S into a tall paint tray, such as a Wooster® Wide Boy™ 5-gallon paint tray.

DO NOT POUR Smith’s Hi-Wear 90S onto the floor then spread!

Dip the 3/8” nap roller into the mixture to coat the roller head then roll off any excess into the paint tray avoiding liquid build-up on the sides of the roller caps and/or the frame. Avoid dripping Smith’s Hi-Wear 90S during placement on the floor as the fillers will concentrate in the drip & may not evenly disperse while finishing the coating.

NOTE: DO NOT TURN THE MIXING VESSEL UPSIDE DOWN ON THE SUBSTRATE TO ALLOW THE RESIDUAL PRODUCT TO DRAIN ONTO THE
FLOOR TO AVOID THE RISK OF ANY UNMIXED OR NON-THOROUGHLY
CATALYZED PRODUCT FROM THE SIDES & BOTTOM OF THE MIXING VESSEL
FROM REACHING THE FINISHED FLOOR.

Best practice is to pour the mixed contents into a paint tray then dip & roll onto the substrate when applying Smith’s Hi-Wear 90S. Roll out two parallel pathways roughly 8 to 10 feet in length. Then rewet the roller & repeat.

Next, cross roll in a V-shaped pattern starting at one of the lines on the end working across the area while overlaying one side of the roller to connect & evenly place Smith’s Hi-Wear 90S ensuring a uniform film thickness.

Finish by extending the roller out to the furthest point of this area and pull back across the surface with light pressure in a straight line to remove roller marks & overlap each pass by 1/2” continuing across the entire section.

Occasionally use the roller cover to remix the filler into the liquid in the paint tray. Ideally every 20 minutes. On larger projects, it is recommended to have a separate person perform for each stage of the product placement, V-roll & finishing process to ensure productivity & a uniform appearance to avoid roller lines. If the appearance is less than unsatisfactory, repeat the finish rolling process again until a satisfactory appearance is achieved. Continue until the entire area desired is topcoated & allow to cure.
