To paint a large surface without leaving a mark, one needs to know a minimum of practical rules. It’s also essential to have adequate equipment. Here are a few tips on how to paint without leaving a demarcation.
1 – Choosing the right paint
Making the right paint choice is essential to get good results. When you choose a cheap paint, you take the risk it contains more water, so this product won’t efficiently cover the wall or ceiling. Result: you have to apply several coats which make it loose it’s economical advantage (and makes you lose your time). Also, note that low-cost paint has a tendency to leak and generate toxic emanations. Also look for a paint that allows touch-up without leaving marks.
You are thinking about painting a large surface? Aim for high-quality paints. The investment allows you to save time without spending more money at the last moment.
2 – Choosing the right tools
Nothing is better than a large roller to paint an interior surface. If this is your objective, don’t try to save money: a low-quality roller could leave lint on the surface. For the edging and finish, do not use cheap brushes as they could loose hairs. By buying quality, you could get great results and keep your materials for next time.
To paint a large exterior surface, prefer a paint sprayer. This expensive tool provides a smooth and even finish. Indeed, the spray will easily fill all holes, cracks, nooks, and crannies.
3 – Maximizing the adhesion
For interior paint, applying only one coat is not recommended. Some walls have a tendency to absorb paint, which leaves a serious demarcation once dried. To avoid this, start with a first protection coat (primer) and then a second coat for an esthetic finish. Take in consideration the surface on which you paint. If the surface is porous, for instance, you have to choose a specific paint to avoid leaving marks.
For exterior painting, it is important to prepare the surface properly before applying paint in order to maximize the adhesion. The surface preparation could include a pressure washing to get rid of the mold and other impurities, a surface conditioner, a rust inhibitor, a rust converter, a primer, and others.
4 – Doing the good movements
Not easy to act like a painter when you are not one! This is especially true when painting a large surface or a ceiling. Movements should be smooth and wide, and one must never lean on the roller. If you do not follow those directives, your surface won’t be uniform and you will observe big marks once it’s dried. Also, make sure you read carefully the warning or instructions indicated on the container to respect the drying time between coats.
Good to know
No matter the type of paint you use, make sure the room is properly ventilated. Do not forget to protect the doors, windows, lighting fixture, light switches, and floors with drop cloths.
If you don’t have time to accomplish your work or if this seems difficult and time-consuming, you can also hire a specialized company to get excellent results in no time. Plus, you won’t spend all our money in materials which you might only use once (scaffoldings, rollers, spray guns, etc.).
