Sikagard® HB 200 LR

Proprietary blend of acrylic polymers with special additives dispersed in a water base.

1 year when properly stored

Store in unopened containers in a cool, clean, dry area. Keep from freezing.

8.8–9.3

2–4 hours at 21 °C (70 °F) and 50 % relative humidity.

Note: Lower surface or air temperatures and higher relative humidity will extend the drying time.

1. Surfaces should be clean, sound, and free of all bond-inhibiting contaminants.
2. Mildew and fungus must be completely removed before application of Sikagard® HB 200 LR.
3. Concrete substrates should be fully cured.
4. Repair any holes, spalled and damaged concrete with appropriate Sika® repair materials. Allow appropriate cure time prior to coating.
5. Remove any protruding concrete accessories and smooth out any surface irregularities.
6. High-pressure power wash surface (or abrasive blast on hard, dense surfaces) to create a profile of CSP 3, per ICRI Guide 310.2.
7. Some stains may require chemical removal. Neutralize any cleaning compounds used and rinse with clean water.
8. Check the adhesion of old coatings according to ASTM D3359, Measuring Adhesion by Tape Test Method A.
9. Remove any blisters or delaminated areas and sand edges to smooth rough areas and provide a transition to old paint areas.
10. Treat cracks greater than 0.7 mm with Sika Thorocoat®-746 Knife Grade or SikaWall® FL 748. Treat cracks larger than 6 mm as expansion joints and fill with appropriate Sika sealant.
11. The new CMU must have a base coat of Sika Thorocoat®-749 Block Filler.

1. Prior to use, mix Sikagard® HB 200 LR at a slow speed with a drill and mixing paddle to ensure uniform colour dispersion and minimize air entrapment.
2. In multi-pail applications, mix the contents of each new pail into the partially used previous pail to ensure colour consistency and smooth transitions from pail to pail.

1. Apply Sikagard® HB 200 LR by brush, spray, roller, or spray and backroll.
2. Maintain proper uniform wet-film thickness (w.f.t.) during application to ensure the performance characteristics desired (see yield rates section).
3. Always work to a natural break and maintain a wet edge during application.
4. For uniformity of colour, application techniques must be consistent throughout the project.

Roller

1. Use a quality, 19 mm – 31 mm nap roller cover.
2. Completely saturate the roller and keep it loaded with the coating to build the required mils. Never dry roll.
3. Cross roll, maintaining a wet edge, to achieve uniform thickness. Backroll in one direction for a consistent appearance.

Spray

1. Equipment is available for spraying Sikagard® HB 200 LR. Contact the equipment manufacturer for further recommendations.
2. Backrolling in one direction after spray application is recommended to achieve uniform film thickness.

Brush

1. Application by brush is recommended only for small inaccessible areas, for example, on touch-ups.
2. Use only a nylon brush.

Clean all tools and equipment immediately with water. Cured material may be removed by mechanical means.
