There nothing that gives a home instant charm like a new exterior paint job. Not only will it extend the lifespan of your siding and trim but it will increase the value of your property.
Exterior Painting Preparation
Aside from the quality of the product being applied, the preparation is critical to ensure an excellent painting job. Poor preparation is probably one of the main reasons why most paints fail. On houses that are very neglected the preparation can take twice as long as the actual painting.
Before the conclusion is made on which product will be used it is vital to understand what product will work best. A high-quality paint will not go very far on a porous substrate despite proper preparation and primer should there be no ideal bonding. In such a situation, it is advisable to apply an economical coating and to redecorate the particular area more often if needed.
Secondly, a good water-based acrylic paint can, depending on the application, last a lot longer on certain steel structures than the best enamel paint. Not only is it quicker and easier to apply, but it can also cost 50 % less and last longer.
Prepare by cleaning thoroughly with a high-pressure cleaner to remove all dust, dirt, loose and flaking paint. Cracks should be chopped or raked open and needs to be filled with cement or a quality filler after being thoroughly prepared with a high-quality masonry primer. Once filled and allowed to dry, the filled areas have to be primed again.
Occasionally, a thin fibre tissue can be applied over the part where the crack was filled. Should there be visible hairline cracks, it is advisable to apply a generous layer of flexible texture paint to bridge and eliminate all of these fine cracks.
This can be followed by a second texture layer, but texture coats have a greater dirt preservation and for that reason typically collect dust and dirt sooner than later. However a mid sheen pure acrylic is usually the best option for a second coat since it has a smooth low dirt retention surface which will keep the walls cleaner for longer and marks are also easier to clean compared to a texture coat.
It is important to make use of a quality texture coat that allows for a bit of flexibility, as some coats dry out to become a hard coating and many of the hairline cracks reappear within six months.
Painting Asbestos Gutters
Many of the older asbestos gutters are often somewhat porous allowing them to gradually absorb water internally, causing the exterior paint to blister and peel and thus shouldn’t be painted with a high-quality paint that forms a ‘solid ” coating. A lower quality paint will usually let the water slowly leak right through the paint, stopping it from peeling and consequently last longer.
