Cracking Flaking: The splitting of a dry paint film through at least one coat, which will lead to complete failure of the paint. Early on, the problem appears as hairline cracks; later, flaking of paint chips occurs.
Use of a lower quality paint that has inadequate adhesion and flexibility.
Over thinning the paint or spreading it t(x) thin.
Poor surface preparation, especially when the paint is applied to bare wood without priming.
Painting under cool or windy conditions that make latex paint dry too fast.
It may be possible to correct cracking that does not go down to the substrate by removing the loose or flaking paint with a scraper or wire brush, sanding to feather the edges, priming any bare spots and repainting. If the cracking goes down to the substrate, remove all of the paint by scraping, sanding and/or use of a heat gun; then prime and repaint with a quality exterior latex paint.
Exterior Painting – Frequently asked questions
Can I paint over aluminum/vinyl siding?
Yes. Always make sure the surface is cleaned to remove any chalk or dirt. Never apply paint that is darker than the original painted surface on vinyl siding.
Do I need to wash my house before I paint?
Yes. Surfaces must be clean before painting. Thoroughly wash with a house cleaner and water solution, making sure to remove any and all mildew. Rinse and allow to dry.
How much paint do I need?
Be sure to utilize our Paint Gallon Calculator in the Project Planner section to help you determine how many cans to buy for your next project.
To achieve one-coat coverage, paint should be applied at a maximum of 400 square feet per gallon. Rough or textured surfaces may require more paint. On these areas allow for 25-30 square feet per gallon. Some bright colors may require multiple costs to achieve sufficient hide.
How do I apply the paint?
When using more than one gallon of the same product, mix the gallons together to insure color and sheen uniformity. Two coats of this paint will provide maximum protection.
How do I paint shingles & shakes?
Shingles offer natural breaking points, paint in a vertical direction.
How do I care for freshly painted surfaces?
We suggest not washing your newly painted surface for at least 30 days. After that time, dirt and stains may be removed using a mild, non-abrasive cleanser and water.
I have never painted the exterior of my home before….?
When painting the exterior of your home always start with a clean surface; paint one side of the house at a time, starting with the highest point; apply a full even coat to one side of the house at a time and always paint the trim last.
What conditions are best for painting my house?
Generally you should only paint when the surface is between 50F and 85F. High temperatures cause the water in the paint to evaporate too quickly, while low temperatures prevent latex from covering properly. Always avoid painting in direct sunlight, strong winds, or when rain is expected within 8 hours.
What tools do I need?
Depending on your project and the type of structure you are painting, paints may be applied with a nylon/polyester brush, a paint pad or spray unit.
What is the proper way to use spray equipment?
It is always safe to operate spray equipment with safety cautions. Use respiratory and eye protection. All spray units are different and it is important to follow the manufacturer’s instructions carefully.
