The present invention relates to a finely-powdered, storage-stable powder-like product containing alkali silicate and a production method thereof. Said alkali silicate is used, inter alia, as an ingredient reinforcing cement monomer or paint and to provide waterproofing. According to the present invention, for a solid, glassy alkali silicate mass a mechanical grinding is performed for changing the mass into rapidly water-soluble powder with particle size below 100 ,µm, whereafter a finely-powder, non-hygroscopic stabilizer is mixed in the powder to prevent the product from caking. For the stabilizer, inter alia, light aluminium silicate pearls nonsoluble in water and extremely finely-powdered quartz powder can be conceivable. A product containing alkali silicate and stabilizer can according to the invention be included as an ingredient in dry, finely-powdered monomer, cement or paint, whereby they can be brought into useful, hardening state merely by adding water on the site.
