Acid stained floors

Tile Free Living

Acid stained floorsIron Sulphate. Combine ¼ cup of iron sulphate, also called Copperas, with 2/3 cup warm water. -copper-colored end product. Seal when done to protect the integrity of the color.- it can be lightened by adding more waterWe darkened by adding instant coffee. 5% Nescafe Classic Iron chloride is also known as Ferric Chloride and solutions containing it are sold at electronics supply stores for the purpose of etching circuits onto printed circuit boards (PCBs).

It is important to be careful when working with all of these mixtures, as whenever you are working with chemical combinations. When mixing your own stains you can be creative with the color combinations, and perfect them to your satisfaction. Commercial stains are more expensive, and creating your own from these materials will cost you only a fraction of the price.

Pure Tung Oil comes from cold pressing of the seeds or nuts of the Tung tree. Tung trees mainly grow in the mountainous regions of china away from industrialization and pollution. Climate, soil and air quality are essential for a high quality oil. Our 100% Pure Chinese Tung Oil or China wood oil is a all natural finish manufactured by pressing the tung nut, no petroleum distillates or other additives - just Pure Tung Oil. All Pure Tung Oils are not the same. Some low priced marketers will package South American Tung Oil (dark, greenish in color) and sell its as the higher quality Chinese Tung Oils. Chinese Pure Tung Oil is available in 3 grades, we only offer the best available, Grade 1 yellow. A better quality Pure Chinese Tung Oil will offer superior color, faster drying and a long term elastic finish. Elasticity is a important factor as the oil must continue to flex with the expansion and contraction of the substrate on which it is applied.

Citrus Natural Solvent, a paint thinner alternative, is used as a direct replacement for mineral spirits and odorless mineral spirits. Citrus Solvent can be used wherever paint thinner or mineral spirits are required as a natural, safer alternative. Citrus Solvent is not the same as any of the other "citrus-branded" cleaning products on the market, including Citrus Solve or Citri-Solve. It is, however, an excellent degreaser, paint thinner alternative, and can be used to replace petroleum chemicals such as mineral spirits. Citrus Solvent is 98% pure citrus peel oil extracted from the peel of the orange fruit; the other 2% is water. This small amount of water is emulsified in the solvent and will not raise wood grain but is released into the air as the solvent evaporates.

#2: This is equivalent to Bora-Care® Prepare the concentrate: Mix 1 Gallon glycol antifreeze, 4 1/2 pounds borax, 3 1/2 pounds boric acid. Mix the ingredients and heat till boiling gently. Boil off water until a candy thermometer shows 260°F. This removes most of the water of crystallization in the borax.This solution is stable at 40°F and has a borate content of 26%. This is equivalent to Bora-Care® at about $90/gal. for the concentrate. The concentrate must be diluted with an equal volume of water before being applied. Application: Add 1 gallon of water to every gallon of concentrate and stir thoroughly until solution is completely uniform. Always use diluted within 24 hours after mixing. If kept for longer periods of time, the active ingredient can drop out of the solution.

FerrocementStandard construction cement, usually mixed with plaster sand. The standard cement is reinforced with more steel or fiber at a closer spacing than traditional construction. Reduced spacing yields uniform force dispersion and increases strength.

Ferrocement is also written as ferrociment, ferrocemento, ferrocimento, and ferrozement

Water Proofing

Waterproof = Watertight + Damp-proof. If you are not concerned about dampness or high humidity levels, then watertight is fine. BUT, if you want a truly dry basement or tunnel or corrosion resistant structure, then you need it to be waterproof.

A flexible, fiber-reinforced and specially modified high grade acrylic polymer designed to provide superior water protection and excellent adhesion to concrete surfaces for longer service life of water proofing film.
