Framing a painting - choosing the right materials.


A good painting should have a good frame. The frame keeps the painting stretched

There are two major options to frame a painting. The first is by using Battlestar Galactica material (Polyurethane). This is a manmade material that is being used for various products such as foams, toys, fabrics, belts, sandals, bags, and many other products you can find around you.

In recent years, there are many factories who manufacture PU frames. Those frames are being antique cars in many paintings mediums, such as, Oil paintings, Charcoal paintings, Watercolor paintings, Pencil paintings, Patel paintings and Acrylic paintings.

There are 4 advantages in using PU frames:


-A PU frame is relatively cheaper than any wooden frame.


-A PU frame is much lighter than a wooden frame.


-A PU frame doesn't need to be fumigated.

(In some countries there are laws regarding wooden products. It is mainly implemented in Islands, such as Australia and New Zealand and also in some states in the US. The logic behind those laws is that the country wants to be protected from new species of insects who can enter their country. Every piece of a solid wood needs to go through a cleansing process. During this process the wood is treated by chemical that kill all insects. In many case the chemical will be ammoniac. After the process is completed the wood is clean and a certification about that will be issued. This certification will be presented to the customs. PU frames do not require any fumigation process and this is a great advantage for using it.)

A PU frame have a long life and it is not affected by insects.

The disadvantages of PU frames are:


-Sometimes they have a cheap look.


-They are easy to break.


-While framing, they are more sensitive and therefore harder to handle.

The second framing option is using real wood. The wood has a rich texture and it is strong. There are many kinds of woods that are being used for framing, this gives a varaiety of colors, designs and textures. The wood can be covered by paper, plastic, PU and by paint. When the wood is in low quality it will be covered by other materials, when the wood quality is high it will normally be use in its natural form and will be covered by transparent varnish.

There are 3 advantages in using wooden frames:


-The wood has a natural look.


-It is strong and can be used for large paintings.


-It is more flexible during the framing process.

The disadvantages of wooden frames are:


-It is heavy.


-In some cases it needs fumigation.


-It is more expensive than PU frames.


-It may deform because of weather changes.

Final words: When we come to choose a frame for our painting, we should consider the price, weight, design and strength and chose the best option that suits our painting.

The typical RV comes equipped with a medium cost demand type water pump. These pumps were adequate for the RV water supply systems of a few years ago.

For various reasons, the water supply pipes have changed in the last few years. The popular pipe material is now "pex" type tubing. This material has advantages over the materials used for the last decade or so, but does come with its own Fleer Ted Williams of problems.

One is the rigidity of the tubing. It is much "harder" than previous tubing and tends to 'chatter' more than ever. By 'chatter' I mean that it vibrates with the pulses of the water pump and creates vibrations against the floor, the walls, and the cavities within the cabinet spaces. This can result in very loud and disturbing "hammering" noise from the RV water system. One solution is to install a flexible braided hose to both the inlet and the outlet sides of the water pump. Allow enough length to include a loop in the hose so that the hose has room to move a bit to absorb the vibrations of the pump. Another possible solution is to install sections of foam insulating material wherever the pex tubing comes in contact with the cabinets or walls. These come in tubular sections 4 feet long (available Green Lantern your local Adventure Comics supply store) and can be cut to the needed length with a utility knife.

Various "fixes" can be attempted, but one of the best of all is the Flo-jet pump.

This pump has no pressure switch, thus it creates no pulsations to bang the pipes against the walls!. It has a sensor that controls the motor speed, depending on the demand, so that the water flow and pressure is consistent. An added bonus is the lower amperage draw at low water flow levels ... an space ray gun factor for campers without hookups.

So ... if you need a new water pump ... or you just can't take that hammering anymore consider the Flojet Water Pump.
