Wood Bleaching System

In Bleaching Wood, Wood Treatments by admin

Floorwood would like to introduce the Litenit Wood Bleaching System. A safe, VOC free, 2- component liquid wood bleach system that will remove the natural color from bare wood. Not a new idea! just one that has been refined to improve the results. Safer, with the discovery of a new activator to pull the tannin to the surface.

Existing 2-part systems require the use of dangerous chemicals to draw out the tannin from wood. All these unfriendly solutions emit toxic fumes on their own. When mixed with the 2nd component, the subsequent gas/vapor would require the use of a full-faced oxygen breathing apparatus.

Liteit’s component “A” is basically a colorless and odorless aqueous solution. When combined with component “B”, the only vapor present from the chemical reaction is a concentrated oxygen.

Basic Instructioins

Ideally the wood you are planning to bleach should be bare timber. Clean, dry and free from coatings, sealers, oils & waxes.   
Part (A)
is the activator. Its job is to pull the tannin and natural colour from the wood to the surface. Easily applied by brushing, rolling or spraying the surface to achieve a wet look. Then massage in to the wood surface with a green scourer, stiff plastic brush, or a red/blue or green pad on the buffing machine. The reason for this step is to break the surface tension, allowing for complete penetration. You will notice rather quickly a the tannin is drawn out, (see fig. A)

Next, apply Part (B)  in the same manner, straight after buffing in Part (A). Be careful with Part (B), as it is a strong grade H2O2 which is corrosive and will burn your skin. So protect yourself with chemical gloves and eye protection. Application and buffing in of Part (B) starts to bleach the extracted tannin and wood fibers, almost immediately. You will notice some fizzing & foaming from the reaction and the not so pleasant colour change. This is normal.

Now we wait until the wood is dry. Atmospheric conditions need to be factored in to the equation. Though usually overnight is required. Once the wood is dry, that’s the level of bleaching achieved from that application. If a lighter colour is required, just repeat the process. Your next and very important step in the process, is cleaning the wood surface to remove all residues from the bleaching reaction. No coatings or finishes at all will stick or cure on the surface without cleaning. Floorwood wood cleaner has been specifically designed for this purpose. It’s easy to use and economical. If there is none available, use only clean water as an alternative. Once the wood is dry from cleaning, it may be coated with any product you like to achieve many different colour, look & feel.
