Micro-Seal Densifier LS Concrete Densifier

RainGuard Pro Micro-Seal Densifier LS is an easy-to-use alternative to sodium or potassium silicates, and does not generate hazardous wastewater. It is a high-quality densifier, hardener, and sealer for concrete surfaces. The lithium silicate (LS) penetrates deeper than potassium and sodium silicates and is much less likely to blush.

When a concrete surface is densified, the harder surface helps make cleaning and surface maintenance easier and provides a dustproof finish. RainGuard Pro Micro-Seal Densifier LS will not contribute to surface Alkali Silicate Reaction (ASR). Ideal for use on freshly placed, steel troweled, uncured, ground/honed, polished, and/or green concrete surfaces.

Features & Benefits

• Deep penetration creates a harder surface and long-lasting performance
• Quick cure time, approx. 1 hour
• Easy application only requires one coat
• Non-flammable and non-toxic formula with low odor
• Does not crack, peel, or turn yellow

Coverage (theoretical)

• Freshly Placed, Steel Troweled, Uncured Concrete - 700-900 sq. ft. / gallon
• Ground/Honed and Polished Concrete - 500-800 sq. ft. / gallon
• Green Concrete - 300-600 sq. ft. / gallon

Uses

Staining or Dyes

Stains and Dyes can be added onto the concrete after the grinding process, and before the application of MicroSeal® Densifier LS. Allow the stain or dye to dry sufficiently before applying Densifier LS.

Polishing

Densifier LS can be polished to achieve different levels of glossiness. The higher the grit, the higher the gloss. Do not exceed 3,000 grit polish. Increase the grit levels depending on the desired gloss in increments. Most applications are polished 3 to 4 times with different grits, starting with a 200-grit, then 400-grit, 800-grit, and finishing with a 1,500 or 3,000 grit. We recommend the use of resin-bond diamond pads.
