Chalking is the breakdown of a outside layer binder due to exposure to the ultraviolet (UV) rays of the sun. Causes included as below: - Failure to correctly prime and seal a surface.
- Excess thinning the paint.
- Spreading the paint too thinly.
Oil-based paints are additional prone to chalking than acrylics. While it is normal for paint to wear over time, extreme chalking must be resolved to ensure that the new coat of paint will bond.
Checking is a model of breaks in the top layer of a coating. Cracking and flaking are higher stages of checking. Checking results when a coating begins to lose its elasticity, developing small narrow breaks due to expansion and contraction. These break is on the surface and do not penetrate to the substrate. They frequently follow the pattern of the grain. Further exposure will result in wider break or cracks in the coating that eventually reach the substrate. As time goes on, the coating begins to flake off.
- exterior primers to major bare wood prior to applying a topcoat. Most exterior oil-based primers contain resins that allow some penetration and breathability. They are more flexible than interior types and could contain stronger mildewcides and fungicides. They are a good choice for blocking out stain such as cedar tannins that may leach through water-based coating.
- topcoat of either a high quality acrylic or oil-based paint. The 100 percent acrylic paints are measured to have more flexibility, are able to breath and have a longer life when exposed to direct sunlight. On the downside, they tend to be less abrasive than oil-based paints and are not recommended for areas where pooling water can accumulate.
- the coating manufacturer's recommendations for normal maintenance.
- any existing or potential troubles as outlined in this brochure. Remedies provided are guidelines and must not replace a manufacturer's specification or guarantee. - that pressure washers are put no greater than 500 pounds per square inch (psi). Use of higher pressure might result in damage to wood fibres or create moisture problems. Both may affect the performance of a new coat of paint.
- all movable paint by scraping and sanding or by using organic strippers. Check with your local paint store expert for options.
-Fill any holes in wood smaller than 1/4" with flexible filler such as linseed oil putty. For larger imperfection, it is advisable to use a non-shrinking two-part epoxy-based filler.
The materials used in constructing heritage buildings are often considered well above the standards found in those built today. This is just one of the reason why heritage restoration is considered a good investment. But exposure to the environment, in some cases for over one hundred years, will eventually cause some structural wear, particularly where regular maintenance has not been done. Realizing that each heritage painting project will be different, it is safe to say that unless houses have been properly maintained, each will have encountered similar problems during its lifetime. Unless proper remedies were applied, it is possible that these troubles still exist and should be corrected before a new coat of paint is applied. About 85 percent of coating failures are the result of poor training of surfaces. Once proper paint restoration has been finished, ongoing maintenance is important. By keeping the same color scheme, it is necessary only to recoat the worn or failing areas. For example, the south and southeast sides of homes in
The principles of lead safety during remodeling also include restricting access to the work area by not allowing children or pets to enter, laying thick plastic sheeting on the floor to collect dust, use of a HEPA-filtered vacuum, wet washing surfaces to clean thoroughly at the conclusion of each day and the end of the job, and individual attention to cleaning with repeat washing with detergent and vacuuming to pick up all remaining dust. In preparing the surface for painting, be aware that dry sanding or dry scraping may produce undesirable lead dust, so spray a mist of water onto the surface to be prepped. These “wet sanding” and “wet scraping” methods generate much less dust than its dry counterparts and is required by law. Also, do not use methylene chloride, a general ingredient in paint strippers, to strip lead based paint. There are specialized paint strippers for use with lead paint such as LEAD-OUT Paint Stripper, Strip-Tox, Lead-X, and others. Some of these particular strippers render lead non-hazardous decreasing the risks associated with lead paint removal.
HUD require a dust test for "clearance" at the end of any remodeling or repainting job be performed by a third-party professional who is independent of the entity performing the work. Contact your state's lead-poisoning prevention program or appear in your Yellow Pages director under "lead paint" or "environmental consultants" to set a lead-based paint professional who can do a clearance examination for your job.

Deciding whether to paint the exterior or interior of your home yourself or employ a home painting contractor is a hard choice. Whilst doing it yourself is cheap, it is time consuming and will eat into your leisure time, or indicate that you have to sacrifice vacations or wages.

Contractors will do the job very fast, and will finish the job speedily, causing a minimum of disruption and ensuring professional quality. A good home painting contractor will be prompt and courteous, showing up on moment and never sounding vague or unsure. When they offer a quote, do not be afraid to ask for a breakdown and enquire how accurate this estimate is. Unscrupulous contractors have been known to rack up the last bill.
The term Renaissance was first used by French art historians of the late 18th century in reference to the reappearance of traditional architectural forms on Italian buildings of the early 16th century. The term was later expanded to include the whole of the 15th and 16th centuries and, by addition, to include sculpture, painting, and the decorative arts. There is still considerable disagreement among art historians as to whether the term should be restricted to a phenomenon that had its origins in Italy and then spread through western Europe or whether straight contemporary developments north of the Alps, and specially in the Low Countries, should be included on an equal footing with what was happening in Italy. During the Renaissance, practitioners of all the arts evolved from anonymous craftsmen to individuals, often extremely respected ones. Painting became more intellectual, sometimes to its own disadvantage, and changed from serving as a vehicle for didacticism or decoration to becoming a self-aware, self-assured form of appearance.
For the sake of convenience, painting of the Renaissance is divided into three periods, even though there is considerable overlap depending upon the painter and the place. The early Renaissance is reckoned to envelop the period from about 1420 to 1495. The High Renaissance, or classic phase, is normally considered to extend from 1495 to 1520, the death of Raphael. The stage of Mannerism and what has more recently been called late Renaissance painting is considered to extend from the 1520s to approximately 1600.
Conventional paints are commonly classified into two categories: water-based and oil-based . Oil-based paints are sometimes referred to as solvent-based. Paints consist of a resin or binder, pigments, and a carrier. They also consist of solvents, toxic metals, and volatile organic compounds (VOCs) that can cause smog, ozone depletion, and indoor air quality troubles with negative health effects. These unhealthy ingredients off gas into the air during the application and curing of paints, and even after the paints are dry. Once paint is applied, the carrier evaporates leaving behind a solid coating. In oil-based paints the carrier is a solvent consisting of VOCs. Titanium dioxide, a pigment used in nearly all paint production, is manufactured using a extremely polluting and energy intensive process. It reacts with sunlight to donate to smog when used in exterior application, and poor indoor air quality when used in interior application. Fungicides and preservatives (collectively known as biocides) are added to latex paints to combat mildew.
