Plaster repair sounds easy, but even small mistakes can turn a simple fix into a costly problem. Whether you’re dealing with cracks, holes, or old lath and plaster, doing it wrong can damage your walls permanently. At GONZALEZ PLASTERING, we specialize in flawless plaster repairs and know exactly what mistakes to avoid.

Skipping Proper Surface Preparation

A solid foundation is everything. One of the most common mistakes is ignoring surface preparation. Dust, loose paint, and moisture can all cause the plaster not to stick properly. Before applying new plaster, always clean, dry, and smooth the wall. A well-prepared surface gives you a long-lasting repair that won’t fall apart in a few months.

Using the Wrong Materials for Plaster Repair

Not all plaster repair materials are made equal. Many homeowners use cheap patching products that don’t match the original plaster strength or texture. Using the wrong type can lead to weak finishes, poor blending, and future cracks. Trusting experts like GONZALEZ PLASTERING guarantees the use of the right professional-grade plaster that matches perfectly.

Poor Mixing and Application Techniques

Mixing plaster correctly is a skill. If it’s too thick, it becomes impossible to spread; if it’s too watery, it won’t stay on the wall. Poor mixing results in bubbles, cracks, and unlevel surfaces. An even, consistent mix creates a smooth finish that looks fresh and strong. Always remember: the art of plastering is in the details.

Rushing the Drying Process

Rushing the drying process is yet another big mistake. Some homeowners use heaters, fans, or direct sunlight to speed up the process. This can cause shrinking, cracking, and weakness in the newly repaired area. Allowing plaster to air dry naturally ensures a solid, lasting bond.

Painting Too Soon After Plaster Repair

Jumping into painting too early is a recipe for disaster. If you paint over wet plaster, the paint will bubble, peel, or trap moisture inside the wall. Always wait until the plaster is fully cured and dry. Professionals at GONZALEZ PLASTERING recommend checking for color changes — fully dry plaster becomes a light, uniform color before painting.
