The term sapstain and blue stain is used in many articles concerning rot and wood preservation. One should understand this term as a first step in understanding wood degradation and rot.
What is Sapstain?
A tree consists of many parts, but for this short treatise two terms, heart wood (physiologically dead wood located near the center of the tree) and sap wood, which are located on the outer periphery of the tree (physiologically active) will suffice. The sap wood carries water and nutrients up though the tree and thus is a perfect environment for sapstain growth.
When a board or timber is cut from a log, mold spores can come in contact with the nutrient rich wood with its inherent high moisture content and they begin to multiply and spread over the face of the lumber.
As they spread they create a stain which is normally blue, but can actually be different colors. Throughout the years I have seen not only blue, but also black, red and yellow.
If this mold/stain is not checked, it can penetrate into the wood with tendrils and take the infection deep into the lumber or timbers. They will eventually emit enzymes which will break down the wood and then you have the start of serious decay. We are talking about lumber which is wet (unseasoned) and in a nutrient rich environment. Many people talk of dry rot; but in reality there is no such thing. This is a misnomer. since wood needs to be between 30 and 60-percent moisture content for it to begin the decay cycle.
Preventing Sapstain
To prevent sapstain from discoloring the lumber and to prevent further degradation through decay, many mills will dip the product into a fungicide to deter mold from attacking the lumber. This is particularly important in the humid areas of the United States and its use is highly recommended for high quality, valuable lumber.
Lumber which has a high propensity of sapstain will not take a finish evenly. The area which has the sap- stain will absorb wood finishes more than unaffected areas. Thus, when finishing a piece of lumber so infected, one will have to use a number of wood finish coats to even out the look. For high quality products such as furniture or mouldings, the lumber infected with sapstain is discarded.
If one is installing wood which has mildew present, it should be washed thoroughly before applying any type of finish. We are talking about a surface coating of mildew, not a stain that has penetrated deep into the wood. Use a mixture of three quarts of water, one quart of household bleach, and 1/4 cup of liquid dishwasher detergent which does not contain ammonia. Never mix bleach and ammonia as it will give off hazardous fumes. This formulation can be sprayed on using a pump sprayer. After 15 to 30 minutes, it can be washed off using a power washer.
Remember that once the stain goes deep into the wood, it cannot be removed with bleach or any other product. It is there to stay. Always remember not to play chemist and experiment by mixing various chemicals as they could give off hazardous fumes...and more!
When considering the type of equipment to purchase for exercising at home or the office, a free standing pull up bar gives you many advantages over a bar that is attached to a doorway or wall. There is no need to drill holes and mount unsightly brackets. Many rental properties would frown on this. The device affixed to the doorway or wall also must be moved and reset with each use, if you don't want the piece to be visible when entertaining and having guests over.
The portable option is typically what profession gyms and clubs use. They are available in a variety of prices and models. Professional pieces of equipment such as this can cost up to 00 or more. There are many more models available for home use that may provide similar quality and features, though it is recommended that you shop around to find the best value for your money. An inexpensive home model can be purchased for around 0.
Having portability means that the piece can be moved, for remodeling or when you need to change the arrangement of your home. Gyms use such equipment for their portability as well. If you do move, there is no worry about removing the screws or hardware from wood work or wall studs.
The only downside is that this equipment does take up some space, as the legs of the base are fairly wide to keep the machine balanced. However, it does not take up more room than any other type of home gym equipment. If you have a room or large space already dedicated to home gym work outs with other pieces, it is likely you will have room for this apparatus.
Extra features on this equipment include devices that allow weights to be added or removed. This can help you increase the resistance in your workout. It is also a great feature for homes where more than person will be using the equipment. Some models also include a dip station for doing dips. This allows for more flexibility in your workout.
Some even have assisted pull up options that allow you to do pull ups with less than your body weight. These models are often more expensive but you can often find them in your local gym or health center.
Regardless of the model you select, you should make sure it is made from quality materials that is sturdy and durable.
