PROSOCO Sure Klean® Weather Seal Blok‑Guard® & Graffiti Control WB 6 (5 GL)

Sure Klean® Weather Seal Blok-Guard® & GraffitiControl WB 6 is a clear-drying, water-based silicone emulsion for weatherproofing concrete block, brick, unglazed terra cotta, porous tile, concrete and some natural stones. Blok-Guard® & Graffiti Control WB 6 protects interior and exterior masonry surfaces from graffiti attacks without altering the natural appearance.

Application

Protect people, vehicles, property, plants, windows and all non-masonry surfaces from product, splash, residue, fumes and wind drift. Protect and/ or divert foot and auto traffic. Surface should be clean, dry and absorbent. If cleaning is necessary, use the appropriate PROSOCO cleaner. Do not use raw acids. Let cleaned surfaces dry completely.

Dilution & Mixing

Do not dilute or alter. Apply as packaged.

Application Instructions

Lightweight block and porous masonry will need two coats; see “Second Coat Application" below.

Sprayer

1. Saturate, “wet-on-wet” spraying from the bottom up. Avoid excessive overlapping. For textured and porous surfaces, apply enough material to create 6–8 inch rundown below the contact point. NOTE: When spray applying to fluted architectural block, spray in an “overlapping X pattern” for complete coverage of recessed surfaces.

2. Let first application penetrate masonry surface for 2 to 3 minutes. For textured and porous surfaces, reapply in same saturating manner to ensure complete coverage of recessed surfaces.

3. Immediately brush out runs and drips to prevent build up.

Brush or Roller

Recommended for small scale application or when spray application is not appropriate. Saturate uniformly. Let product penetrate for 2–3 minutes. Re-saturate. Brush out heavy runs and drips that don’t penetrate.

Second Coat/Porous Surfaces

Some surfaces will need an additional coat of BlokGuard® & Graffiti Control WB 6 for maximum protection. Apply the second wet-on-wet coat as soon as the first application is dry to the touch or within one hour. Immediately back roll or brush out runs and drips for a uniform appearance and to prevent build up. Allowing more than one hour between coats could reduce the effectiveness of the second coat or cause darkening.

Drying Time

In normal weather (60–80°F; [16–27°C] 50% humidity), Blok-Guard® & Graffiti Control WB 6 dries to the touch in about 1 hour. Drying takes longer at lower temperatures. Blok-Guard® & Graffiti WB 6 Control gains its water-repellency properties in 24 hours. Graffiti resistance properties fully develop in 3 to 5 days, depending upon climate conditions. Protect treated surfaces from rain for at least 6 hours after application.
