Lesson 5 : Interior And Exterior Wall Painting

Procedure For Painting The Exterior And Interior Wall Surface

Exterior Wall Surface:

Over time, the exterior of houses will need general maintenance, including painting. The exterior of the house includes siding, trim, pergola, lldeck work, fences and brick foundations. Because these areas are all exposed to the weather, will need to select exterior paint that will hold up in different types of weather conditions

1. Decide what exterior area of house you want to paint. The area of painting will determine if it's better to purchase an exterior paint or a stain.
2. Determine what the surface of the area to paint. Different surfaces require different types of exterior paint. Therefore, the surface will give insight as to the type of exterior paint one should purchase to best cover that particular surface. Alkyd paints can be used for glossy surfaces. Latex paints can typically be used for other areas.
3. Choose an exterior color or type of stain to use.
4. Select the finish of exterior paint. Types of exterior finishes include flat, semi-gloss, gloss and clear finishes for wood grains. Choice depends on the area of painting. Latex finishes can be chosen for hardboard siding, vinyl or aluminum siding, brick, block, stucco and concrete and an alkyd finish for ferrous metal or galvanized metal. Both can be used for wood or plywood siding or wood trim

Interior Wall Surface:

When it comes to choosing paint color can really be a challenge. There are so many choices and it is difficult to pin point a paint colour and finish.

The tips include -

1. Explore varieties and be patient: It's great to collect paint chips when planning a room, but hold off making final choices until overall room scheme is developed. Paint is available in literally an infinite array of colors and is the most versatile element of any room decor, the easiest to change, and the least expensive. Get ideas but make the final decision after rugs, wallpaper, and fabrics are finalized.
2. Coordinate Decorating Samples: Before actual shopping, it is necessary to have collection of fabric, carpet, tile, wallpaper, and trim samples constantly.
3. Really Study the Colors : You'll find clues about the underlying tones of different shades of a color on a full sample strip of coordinated colors. Even if you're not even considering using a darker tone, look at all the colors carefully. Decide if the family of colors is the direction you're headed with your color selection.
4. Choose the Paint Finish for the Job: Consider which paint finish might be best for the project. Matte or flat finishes hide wall imperfections, but glossier finishes will reflect more light.
5. Plan painting schedule : Survey all the areas to be painted with the painter, evaluate and take stock of all the requirements.. The objective is to free enough space at a time to cycle surface preparation, priming, painting and intervening drying time. Painting during the rains and in very windy conditions is to be avoided and remember to keep rooms well ventilated at all stages of painting.
6. A paint job is basically a 3-stage process, punctuated by drying time after each stage :
• Surface Preparation - which is different for new and previously unpainted surfaces and previously painted surfaces
• Priming - this stage is mainly protective in nature and critical for the enduring performance of paint systems
• Paint Application - the final stage when the finishing coats are applied
7. While choosing paints and budgeting, one should remember:
• Different surfaces require different kinds of paints which have been developed specifically for that surface.
• Painting involves a system comprising at least two components, a paint and a primer, and sometimes a third, a thinner. To get the desired results, you must use the recommended primer. With water-based paints, water is the thinning agent. For solvent-based paints, you need the recommended thinner.
• Primers are available in both water and solvent based versions.
• Paints, primers, tools and accessories make up only part (usually half) of your total painting costs; the other part is cost of labour, which may vary from place to place. Armed with this knowledge one can confidently select a painter, evaluate his knowledge, his estimate for the job, and the suitability of his manpower.
