CEMIX® CEMSEAL WATER BASED (WB) is a readily absorbed silane-siloxane emulsion which acts as a high quality general purpose water repellent for impregnating and priming a variety of surfaces. There is little or no impairment of the materials’ ability to “breathe”, allowing water vapor to exit which helps prevent condensation and mildew on inside walls. The treatment does not produce any discoloration or darkening of the surface and has excellent weathering properties.
TYPICAL APPLICATIONS & USES
Surfaces should be clean, free from grease, loose particles, dirt, paint, curing compounds etc. Moss or algae growth should be removed with suitable treatment and washed with clean water. For maximum penetration on a very smooth concrete surface, acid washing or water blasting is recommended.
Shake or stir thoroughly before use. CEMIX® CEMSEAL WB should be applied, without diluting, in two coats to ensure complete coverage and saturation of the substrate. Spraying is the preferred method with larger areas, using either conventional paint spray equipment or a garden sprayer. Ensure coverage of at least 5m2/L per coat is achieved. On absorbent surfaces, repeat or increase rate of application until surface is completely saturated. Re-application at a later date is possible if required. Equipment should be washed out in water immediately after use.
Before applying any sealer on a fresh concrete, ensure a minimum of 28 days for curing.
