Substrates on contemporary homes are often sided with manufactured products such as Hardi-Plank, Pressure treated trim,T-111 siding, stucco, etc. It is critical these surfaces are properly protected from the elements.
Issues such as separated and cracked caulking on joints, swelling and fissures in t-11 from moisture intrusion, cracks and mildew growth on stucco can all be addressed by a qualified Painter using the right products for the job. For instance, XIM Company has a product called Peel Bond. This product is almost like a paste out of the can but dries clear and forms a nice thick elastic membrane over the cracked siding. It also helps keep any loosely adhered coatings from peeling on the edges. Keeping moisture out of the laminated siding is critical if you would like to avoid replacing it.
Exterior painting projects on older homes is often more of a home renovation.The foundation for a well engineered exterior paint job lies in a properly prepared substrate. Cedar siding and trim found on historical homes in this area are amazingly restorable but often require more than a steel scraper and a can of paint to keep a them isolated from the elements.
Unfortunately many painting companies simply scrape off what is visibly loose. Every couple of years the cycle starts again. The problem often lies in the initial bond of the coating to the wood. If the initial prime coat its 80-100 years old with many layers of hardened paint on top of it, these original and subsequent coatings will continue to pop off the substrate. It is often necessary to remove all layers of coatings down to the wood in these problematic areas of the house. If the cedar siding has begun to fissure or rot, those areas are replaced with new siding. When rot is discovered on the trim we can often extract the damaged fibers , dry the area out and then solidify and pack in the voids with a lifetime epoxy. We then re-apply product to dry, properly abraded and sound surface. We use a penetrating breathable primer and then top coat with a premium 100% acrylic. The end result is a finished appearance which is smooth, free of paint voids and is equal to or surpassing the original. Here is more information if you are looking for quality
Many homes built in the 70’s 80’s and 90’s have second growth cedar siding which contain knots that may become partially detached from the surrounding structure. This allows moisture to intrude into the surrounding wood fibers and will soon start to rot. This process happens over time when the siding has not been properly sealed and coated. After a detailed preparation process to remove the loosely adhered coatings, all knots are then encapsulated and sealed with a lifetime rated elastomeric sealant. The end result is a well protected surface. When painting this grade of cedar siding, make sure to work the paint into the surface with a brush. A good stiff bristle brush will help ensure proper coverage into the cracks that spray application will not get to.
