Common Paint Problems and Handy Solutions
By Debbie Zimmer
The Rohm and Haas Paint Quality Institute
Paint is a valuable ally that can help protect and rejuvenate your home's exterior. The spring or early summer is an opportune time to look for signs of early paint failure. Some paint problems may be caused by using a low quality paint, not preparing the surface properly or painting when it's too hot or cold.
No matter what the cause, now is the perfect time to check those painted outside areas, identify any potential problems, and make valuable corrections before your minor paint problem becomes a larger issue.
Bubbles resulting from localized loss of adhesion and lifting of the paint from the underlying surface.
Painting a warm surface in direct sunlight
Moisture escaping through the exterior walls
Exposure of latex paint film to dew, high humidity or rain shortly after paint has dried, especially if there was inadequate surface preparation
If blisters go down to the substrate, try to remove the source of moisture.
If blisters do not go all the way down to the substrate, remove them by scraping, then sanding; prime any bare wood and repaint with a quality exterior paint.
Cracking and Flaking
The splitting of a dry paint film through at least one coat, leading to complete failure of the paint. Early on, the problem appears as hairline cracks; later flaking of paint occurs.
Overthinning the paint or spreading it too thin
Use of a low quality paint that has inadequate flexibility
Painting when it is too cold or too warm, the paint will dry too fast
If the paint is tightly adhered to the surface, lightly feather the edges, prime and paint
If the cracking is all the way down to the surface, then the paint should be removed. Old flaking paint may contain lead, so precautions for lead paint should be followed.
Black, gray or brown areas of fungus growth on the surface of paint or caulk.
Forms most often on areas that tend to be damp and without sunlight.
Use of a low quality paint, with minimal or no additives to prevent growth
Painting over a surface where the mildew has not been removed
Applying paint in “too thin” of a coat.
First test for mildew by applying a few drops of household bleach to the discolored area, then rinse; if it disappears it is probably mildew.
Remove all mildew from the surface by scrubbing with a diluted bleach solution (one part bleach, three parts water), wearing proper safety protection, including rubber gloves and eye protection. Power washing is also an option.
Rinse thoroughly, prime bare surfaces and paint.
A rough, crinkled paint surface occurring when paint forms a skin.
Paint applied too thickly
Painting a hot surface, painting on a very hot day, or high humidity levels
Applying the topcoat to a not completely dried first coat
Painting over dirty or waxy surfaces
Scrap or sand the surface to remove wrinkled paint.
Repaint with an even coat of top of the line exterior paint. Make sure the first coat or primer is completely dry before applying the second or topcoat.
Always follow the manufacturers recommended spread rate.

Bid- A formal offer by a contractor, in accordance with specifications for a project, to do all or a phase of the work at a certain price in accordance with the terms and conditions stated in the offer.
Bid bond- A bond issued by a surety on behalf of a contractor that provides assurance to the recipient of the contractor's bid that, if the bid is accepted, the contractor will execute a contract and provide a performance bond. Under the bond, the surety is obligated to pay the recipient of the bid the difference between the contractor's bid and the bid of the next lowest responsible bidder if the bid is accepted and the contractor fails to execute a contract or to provide a performance bond.
Bid security -Funds or a bid bond submitted with a bid as a guarantee to the recipient of the bid that the contractor, if awarded the contract, will execute the contract in accordance with the bidding requirements of the contract documents.
Bid shopping- A practice by which contractors, both before and after their bids are submitted, attempt to obtain prices from potential subcontractors and material suppliers that are lower than the contractors' original estimates on which their bids are based, or after a contract is awarded, seek to induce subcontractors to reduce the subcontract price included in the bid.
Bidding requirements- The procedures and conditions for the submission of bids. The requirements are included in documents, such as the notice to bidders, advertisements for bids, instructions to bidders, invitations to bid, and sample bid forms.

Terminology: Output Device
Any device that outputs information from a computer is called, not surprisingly, an output device. Since most information from a computer is output in either a visual or auditory format, the most common output devices are the monitor and speakers.
These two devices provide instant feedback to the user's input, such as displaying characters as they are typed or playing a song selected from a playlist.
While monitors and speakers are the most common output devices, there are many others.
Some examples include headphones, printers, projectors, lighting control systems, audio recording devices, and robotic machines.
A computer without an output device connected to it is pretty useless, since the output is what we interact with.
Anyone who has ever had a monitor or printer stop working knows just how true this is. Of course, it is also important to be able to send information to the computer, which requires an input device
Do It Yourself : All about Hammers
A hammer is a tool meant to deliver blows to an object. The most common uses are for driving nails, fitting parts, and breaking up objects. Hammers are often designed for a specific purpose, and vary widely in their shape and structure.
Usual features are a handle and a head, with most of the weight in the head. The basic design is hand-operated, but there are also many mechanically operated models for heavier uses.The hammer is a basic tool of many professions, and can also be used as a weapon. By analogy, the name hammer has also been used for devices that are designed to deliver blows, e.g. in the caplock mechanism of firearms.
Popular hand-powered variations include:
carpenter's hammers (used for nailing), such as the
framing hammer and the claw hammer
construction hammers, including the sledgehammer
drilling hammer - a lightweight, short handled sledgehammer
Ball-peen hammer, or mechanic's hammer
cross-peen hammer, or Warrington hammer
mallets, including the rubber hammer and dead blow hammer.
Geologist's hammer or rock pick
lump hammer, or club hammer
gavel, used by judges and presiding authorities in general
When selecting a general purpose hammer for youself, it's much like selcting a good fitting pair of gloves. The handle should feel comfortable and the weight should not be clumsy feeling. take the time to try several different manufacturers' hammers. Your simple tasks will be much more enjoyable using a hammer that feels like it's part of you.
Question on a University of Washington engineering mid-termI
s hell exothermic (gives off heat) or endothermic (absorbs heat)?
Most of the students wrote Proofs of their beliefs using Boyle's Law, (gas cools off when it expands and heats when it is compressed) or some variant. One student, however, wrote the following:
"First, we need to know how the mass of Hell is changing in time. So we need to know the rate that souls are moving into Hell and the rate they are leaving.
I think that we can safely assume that once a soul gets to Hell, it will not leave. Therefore, no souls are leaving.
As for how many souls are entering Hell, let us look at the different religions that exist in the world today. Some of these religions state that if you are not a member of their religion, you will go to Hell.
Since there are more than one of these religions and since people do not belong to more than one religion, we can project that all souls go to Hell. With birth and death rates as they are, we can expect the number of souls in Hell to increase exponentially.
Now, we look at the rate of change of the volume in Hell because Boyle's Law states that in order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand as souls are added. This gives two possibilities:
1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell breaks loose.
2. Of course, if Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature and pressure will drop until Hell freezes over.
So which is it?
If we accept the postulate given to me by a woman, during my Freshman year, "...that it will be a cold day in Hell before I sleep with you.", and take into account the fact that I still have not succeeded in having sexual relations with her, then, #2 cannot be true, and thus I am sure that Hell is exothermic and will not freeze."
This student received the only A.
