ABSTRACT
Since paint life is dependent primarily upon surface preparation, this aspect of the cleaning and painting program should receive very thorough consideration. The primary requirement of any surface preparation method is to assure that the prepared surface is thoroughly cleaned of any material that would lead to premature failure of paint. However, it must be kept in mind that all paints will fail eventually. Most paint systems failed prematurely because of cohesion or disruption in the film by rusting of the steel. The latter failures may be minimized by careful surface preparation. The surface preparation should remove sufficient deleterious matter so that the type of priming paint used can wet the surface enough to develop adequate adhesion and at the same time eliminate contaminants that cause corrosion between metal and the paint.The two most general classifications are ‘flat’ and ‘non-flat’, and are based only on the gloss level of the coating. Coatings measuring gloss level less than five on a 60-degree gloss meter fall into the flat category and those over five and 15 respectively are considered non-flat. Coatings being specified for use outside the general purposes represented on the product literature. The metallic pigmented category comprises products containing elemental metallic pigments for either aesthetic reason. Water proofing and sealers constitute products intended to prevent water infiltration by forming a film over concrete or masonry. The implementation of this research will undergo different stages like 1.)Planning 2.) Collection of Organic Specimen and selection of appropriate concrete wall test area 3.) Conducting Organic Test on concrete walls 4.) Development of installation methodology. The first two methods if not included in the process for they are standards that should be followed by each researcher, thus all the necessary precaution should be applied while performing the said experimentation. It is also understood that process that will be use in the organic research will under go various test and method configuration.
Evaluation the various paint failures.
The application of the organic material must adopt the all types of weather condition. Therefore proper evaluation of the area and paint failures should be properly identified in order to locate the vital point where the organic compound will eventually be place.
Conduction of Test for the organic material
The selected wall will be place on an observatory basis meaning all necessary data regarding the wall specification and location with the other vital information about the concrete will be recorded, an adhesive that is most appropriate for the wall will be applied to the chosen area, then the organic material which is currently in a block shape will be grind and will be applied on the wall both external and internal area of the wall. When organic material is fully applied on the wall the paint coating will then be lastly applied. Then observation time will be set to know the effectively of the material towards the pain coating.
Development of Application Method
Upon the various test analysis and the application for the actual test site, according to the various structural painters both industrial and local the common encountered problem is how to maximize the adhesion of paint coating and multiple coating would eventually result to flatting, in this research the method is applying only a single coat and with the organic compound in use, there is also part of the method that will be common to all the user of the coating application where in there should be a proper application of the surface preparation.
SIGNIFICANCE OF THE STUDY
The issue of water penetration control in building construction is as old as the trade itself, occurring whenever three conditions exist: 1. Water is present on the outer face of the wall. 2. There is an opening through which water can pass. 3. A force to drive the water through the opening. Thus to prevent moisture penetration into the wall assembly, at least one of these factors must be controlled. Unfortunately, the first condition is unavoidable.
While there are design features such as the use of overhangs or eyebrows over windows than can divert most water away from critical areas, the exterior walls will generally be exposed to rain. The second condition can occur in various reasons, including damage, poor maintenance, or improper material design and/ or installation.
A little more than a decade ago, pressure-equalization technology was successfully incorporated into an EIFS Design. But now with the current problem on how to dispose organic compound, a new innovation on organic compound evolution is being introduce as a moisture absorbing compound to prolong the life span of the concrete walls especially on tropical areas.
From a design standpoint, the first step is to divide the building face into compartments by establishing areas of approximate equal wind pressures. American Society of Civil Engineers (ASCE) Minimum Design Loads for Buildings and other Structures provides procedures and guidelines for determining wind pressure on facades of various building types. For buildings with unusual exposures or unique design features, wind tunnel tests can also be performed.
