Sodium Silicate Solution 16 oz – Water Glass | Silicate Store
Sodium Silicate Solution (Water Glass), 16 oz / 473 ml. A clear, technical-grade sodium silicate solution from Silicate Store in a pint-size bottle, sized for regular shop use, repeat craft projects and bigger repair or sealing jobs.
Sodium silicate solution, widely known as water glass, is a water-soluble liquid silicate used as an adhesive, binder and sealant. The 16 oz size gives you enough for multiple projects without buying in bulk.
Key Features
- Technical-grade water glass in ready-to-use liquid form
- "N" grade chemistry: SiO₂:Na₂O ratio of about 3.2-3.3
- 16 oz (473 ml) bottle: the practical middle size for ongoing projects
- Multi-purpose: adhesive, binder, sealant, crafts and concrete or masonry treatment
- Clearly labeled with identification, handling precautions, first aid, fire-related hazards and emergency response guidance
Common Uses for Sodium Silicate Solution
- Adhesive and binder: bonding paper, cardboard and other porous materials, and binding powders or fillers in DIY mixes
- Sealant: sealing gaps and porous surfaces in repair and shop projects
- Concrete and masonry: a commonly used treatment to help reduce porosity in concrete, stucco and plaster
- Crafts and DIY: hobby, art and experimental projects that call for water glass
How to Use
- Read the label and the manufacturer's Safety Data Sheet before opening the bottle.
- Wear the protective equipment listed on the label and work in a well-ventilated area.
- Test on a scrap piece or small hidden area first. Sodium silicate can be thinned with water for some uses, so start small and adjust.
