Painting New Build: What You Need to Know Before You Start

Just moved into a brand‑new home or finished the shell of a build? The walls are pristine, but they need colour. Painting a new build feels different from refreshing an older house. There’s no old paint to scrape, but there are fresh plaster seams, drywall dust, and moisture that can bite your finish. This guide walks you through the steps that make the job easier, cheaper, and longer‑lasting.

Prep Work: The Foundation of Great Paint

The first rule is simple – good paint starts with good prep. Even though the walls look clean, the plaster is still releasing moisture. Let the whole house dry for at least a week after the final plaster coat before you even think about a roller.

Next, inspect every joint. Those thin‑set tape seams can crack if you skip sealing. Apply a high‑quality joint compound, sand it smooth, and wipe away all dust with a damp cloth. A vacuum with a brush attachment works well for corners and ceilings.

Prime is your best friend. New drywall and plaster love a good primer because it blocks the substrate’s tendency to soak up paint. Choose a water‑based primer with built‑in sealant – it levels out absorption and gives the topcoat a uniform surface. Apply one coat with a roller, let it dry, and you’re ready for colour.

Choosing the Right Paint & Application

When it comes to paint, durability matters more than a fancy sheen. For most rooms, a low‑sheen or eggshell finish offers a balance of washability and subtle look. Kitchens and bathrooms benefit from a satin or semi‑gloss because they handle steam and splashes better.

Pick a paint labeled “low VOC” and “mold‑resistant” if you live in a damp climate. These formulas keep indoor air cleaner and reduce the risk of mildew behind the walls.

Now for the actual painting. Use a 3‑or‑4‑inch roller with a medium‑nap cover for smooth walls and a thinner nap for textured surfaces. Start with a “cut‑in” – a brush around edges, corners, and trim – then roll the large areas in a “W” pattern to keep the coating even. Two thin coats beat one thick one; they dry faster and hide imperfections.

Don’t forget the ceiling. A ceiling‑specific paint resists drips and dries quicker, saving you time. Apply it first, then move on to walls; you won’t have to touch up splatters later.

Finally, let each coat cure for the recommended time – usually 4‑6 hours for water‑based paints – before applying the next. Rushing can cause peeling or uneven colour.

With these steps, your new build will look fresh, modern, and ready for furniture without worrying about fresh‑paint headaches later. Happy painting!
