About
- Siliates uses brochure - [1]
- Silicate mineral paints - https://en.wikipedia.org/wiki/Silicate_mineral_paint
- German manufacturer discussses 3 generations of this paint - [2]
- Impregnate with silicate, and preferably also soluble borate - then treat with carbon dioxide - to make wood fireproof - [3]
- Silicate preservation patents - [4]
- Paint with sodium metasilicate, followed by magnsium sulphate (epsom salt)
- Paint with sodium metasilicate, followed by calcium chloride (deice salt, $20 for 50 lb - patent [5]. After applying the silicate and chloride, the product is calcium silicate, which is insoluble. This should be doable at room temperature [6]. One should be done after the other, as you want the reaction to happen inside the wood fibers.
- Sodium silicate reacts with the calcium hydroxide in hydrated cement paste to form calcium-silicate-hydrate gel that fills cracks. (google it). Thus, if we paint the wood with cement, and then with sodium silicate - we may get a waterproof cement coating. This may be worth trying as well.
- Silicate also reacts with lime to make calcium silicate - making a protective shell that is still breathable. [7]
Designing the Paint
- How sodium silicate has been used in wood prervation from prior art of a recent patent - [8]
- Sodium silicate preserves wood - [9]. Open source this.
Sourcing
- $5/lb for 2.5 lb - [10]
- Sodium metasilicate. $2/lb for 50 lb bag. [11]
- Potassium silicate - <$1/lb on ton scale - [12]
- Sodium silicate - $200/ton - [13]
- But wikipedia says that Minaral Silicate Paint uses potassium silicate. -[14]
- Potassium metasilicate. $5/lb in 50 lb bags - [15]
- $35 for a gallon of 40% solution on Amazon - [16]
Making
- You can make it from potash (KOH) reacted with silica desiccant beads - [17]
Buying
Other Methods
- Acetylation makes wood last for ever - https://en.wikipedia.org/wiki/Wood_preservation.
