How to Patch Peeling Paint


Putty knife or paint scraper, flexible wallboard knife, and 150-grit sandpaper.




1. Using a putty knife or a paint scraper, remove the loose paint from the wall.

2. Using a putty knife or flexible wallboard knife, apply spackle over the scraped area on the wall. Let the spackle dry completely.

3. Smooth the patch with 150-grit sandpaper until the edges have disappeared into the wall surface.

4. Using a paintbrush, apply a coat of matching paint to the wall. Feather the edges of the paint into the surrounding surface to blend the edges of the patch with the wall using 180 — 220 grit sandpaper.

5. To complete, insure there is one full cover coat of primer before finish coat of paint.

Painting tips & tricks

Rub petroleum jelly on the hinges and door knobs before you start to paint a door. If you get paint on them, they will wipe off easily.

To keep white paint from yellowing, add 2 drops of black paint to each Gallon of white.

When painting ceilings, cut a child’s rubber ball in half and put your paint brush in one of the halves to catch the drips.

An old pair of swimming goggles will protect your eyes from paint splatters and drips when painting ceilings.

When painting, protect your hands and face with moisturizer. Cleanup will be easier and the moisturizer will prevent paint from seeping into the pores.

To stop paint from dripping, punch a few holes in the rim of the paint can. When the brush is wiped against the edge, the paint flows back into the can. The lid covers the holes so the paint won’t dry out.

Before pouring paint from a can, cover the rim with masking tape. After pouring, remove the tape — the rim will be clean and the cover will fit tightly.

To remove lumps from paint: Cut a piece of screen to fit the inside of the paint can. Set it on top of the paint and let it float down to the bottom of the can. It will take all the lumps with it, trapping them at the bottom of the can.

When painting a room, dip a small card into the paint so that you have the exact colour with you and can match accessories in store.

When painting inside corners, trim the paint brush bristles to a V to save strokes and spread paint more easily.

When you poke a paint brush into corners or allow it to rest on the bottom of the paint can, the bristles curl and stray. To straighten natural bristles (not synthetics), try wrapping the brush in a couple of thicknesses of damp cloth and press gently with an iron. The steam and cloth binding do the job. Only light pressure is needed. Let the bristles cool before you unwrap the brush.

When painting old woodwork fill in the holes or cracks with a mixture of flour and some of the paint you are using. It hardens like cement and matches perfectly.

Exterior Peeling Exterior Paint Solution

Peeling: Spontaneous loss of ribbons or sheets of paint due to loss of adhesion. When the surface is coated with a primer and topcoat, or with several coats of paint, the peeling may involve all the coats, some of them, or just the topcoat.

Possible Causes:

Swelling of wood due to seepage or penetration of rain, humidity and other forms of moisture into the home through uncaulked joints, deteriorated caulk, leaking roof or other areas.

Excess humidity or other moisture escaping from within the home through the exterior walls (less likely with latex paints, which allow water vapor to escape without affecting the paint film).
Inadequate surface preparation.

Use of a lower quality paint that has inadequate adhesion and flexibility characteristics.
Applying latex paint under conditions that hinder good film formation, e.g., on a very hot or cold day; in windy weather.

Applying an oil-based paint over a damp or wet surface.
Earlier blistering of paint see Blistering.


If exterior moisture is the cause, eliminate the source by doing necessary repairs and maintenance: replace caulking; repair roof; clean gutters and downspouts; cut heavy vegetation away from the building. If moist air is originating from inside, consider installing vents (especially in rooms that tend to get humid such as the kitchen, bathroom and laundry room); attic louvers, exhaust fans and dehumidifiers may also help. Remove all loose paint with a scraper or wire brush, sand rough surfaces and prime any bare wood. Repaint with a top quality acrylic latex paint — it will provide excellent adhesion and allow water vapor to escape without harming the coating.

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.
