10 House Painting Mistakes That You Can Avoid!


by admin - March 2, 2019

If you’re completely unaware of the potential mistakes one can make when starting a house painting project, you’re most likely to make them! While it may seem like a simple job, one mistake can cause a huge setback and leave you feeling disheartened. On the other hand, if you did your research, all those potential mistakes can be avoided and you will be able to complete your home painting project like a pro!

So, what are these common house painting mistakes that every do-it-yourselfer must avoid? Well, we’ve got them all right here! Read on to find out how you can avoid 10 potential ‘no-nos’ and make your painting experience smooth sailing!

1. Not Prepping the Wall

No matter how ‘ready’ your walls appear to be, you need to carry out standard prepping measures before painting them. This includes efficient cleaning, sanding (if there is an existing wall paint or finish on the surface) and priming. Without preparing the wall properly, you can expect nothing more than subpar results.

2. Excess Brushing/Rolling

If you watch a professional painter at work, you will see that they apply paint to each section of the wall using no more than 3 or 4 strokes/rolls. This is because the paint starts to dry on the surface, causing streaks and ridges when brushing or rolling excessively. So, if you’re painting walls for the first time, consider practising on your garage wall or any inconspicuous area to get the hang of it.

3. Painting in Extreme Temperatures

If it’s too hot or too cold, you will have to reschedule your paint project and save it for a time when the weather is favourable. The problems with extreme climate is that high heat causes the paint to dry and crack, while cold temperatures can leave it wet for days and affect the colour uniformity. The ideal temperature for house painting is between 40 – 90 degrees Fahrenheit; anything higher than the maximum and lower than the minimum are considered risky climate conditions for painting walls.

4. Not Using Paint Samples

While you may look at a particular shade of paint and fall in love with it, bear in mind that many colours look entirely different once they are applied to a wall. Therefore, it’s always wise to ask for samples which can be used on an inconspicuous area of the wall or a garage wall to try out the colour before purchasing more of it.

NOTE: Use a second coat (if needed) and allow the paint to dry completely before observing the colour.

5. Painting Over Gloss/Varnish

If you don’t take the time out to strip off varnish or gloss paints from the wall prior to painting it, the colour and paint will not catch. Moreover, it is likely to peel or ‘bubble’ quickly if the wall is not sanded down. Alternatively, you can use a store-bought deglosser to effectively remove varnish and any existing gloss paint before painting the surface.

6. Getting Paint on the Ceiling

Once you get the hang of rolling or brushing on paint, it’s easy to get carried away. When that happens, you end up accidentally bumping the ceiling, leaving you with an ugly stain of colour where it doesn’t belong! One smart way to avoid this ‘no-no’ is by carefully painting a horizontal border along the top of the wall using a paint brush. This way, you won’t have to paint too close to the ceiling when finishing the rest of the wall.

7. Using Thick Paint

While some paints can be applied to certain surfaces without being mixed, others require to be thinned out using a suitable paint conditioner. Particularly when painting wooden surfaces or textured walls, the paint must be thin in order to apply it evenly. If you’d like, you can have the paint mixed at the hardware store, or simply follow the instructions provided on the container.

8. Exposing the Paint to Air (for too long)

If you leave the paint open for too long, the prolonged exposure to air will cause the paint to dry/harden or thicken quickly. The case is the same when using paint from a tray; hence, it is advisable to pour small amounts of paint in the tray and ensure that the lid is fitted on the tin properly and quickly thereafter.

9. Using a Dirty Brush/Roller

It’s important to use a clean brush/roller to achieve the perfect finish as any debris stuck on the paint tool can leave marks or show unevenness when the paint dries. It’s also wise to inspect the brush/roller as you go about painting your walls to ensure that the paint isn’t drying up which can also cause unsightly runs in the finish.

10. Painting Dimly Lit Rooms

If a room isn’t lit up bright enough to spot flaws on the surface, do not attempt to paint the walls. Often times, homeowners go about painting rooms in what they believe to be bright light, however, when the walls are illuminated by a brighter light source such as sunlight, you will see an entirely different finish. In fact, colours look different in dimmer light as well; therefore, it’s best to begin a paint project when there is a lot of natural light in the room.

NOTE: If you are painting during the day, make sure that the room temperature is suitable for your paints.

So, before you start a house painting project, keep these common mistakes in mind and you’re good to go!
