5 Painting Mistakes That Ruin the Result (And How to Avoid Them)

Even the most expensive paint won’t save the project if the application technology is violated. The result will be unevenness, cracks, and peeling. This article covers the most common mistakes and how to fix them.


Mistake 1: Lack of primer

What happens:
The paint absorbs unevenly, resulting in spots and color variations.

How to do it correctly:
Before painting, be sure to treat the surface with a primer—especially if it’s concrete, brick, plaster, or wood.

What to use:
Oscar Primer — improves adhesion and reduces paint consumption.
Oscar Betonokontakt — for tiles, smooth concrete, and damp rooms.


Mistake 2: Incorrect choice of paint for the surface type.

What happens:
The paint doesn’t adhere, peels off, and quickly loses its color.

How to do it correctly:
Choose the paint based on the material: for wood — enamel or stain; for facades — durable acrylic; for ceilings — matte water-based emulsion.

What to use:
Oscar Deluxe (water-based emulsion) — for interior walls
Oscar facade emulsion — resistant to moisture and sunlight
Oscar Universal Enamel — for wood and metal


Mistake 3: Ignoring application conditions

What happens:
The paint applies unevenly, bubbles, or runs.

How to do it correctly:
Work at temperatures between +10°C and +30°C. Do not apply paint in humid weather or drafts.

💡 Совет: используйте аэрозольные краски OSCAR Duafix в хорошо проветриваемом помещении — высыхают за 15 минут.


Mistake 4: Using low-quality tools

What happens:
Brush marks, clumps, splatters. The paint applies unevenly and looks unattractive.

How to do it correctly:
Use rollers with the appropriate nap length, trays for even paint loading, and painter’s tape for clean edges.

What to use:
Oscar rollers (22–64 mm) — for walls, ceilings, and facades
Trays, brushes, protective films — available in the OSCAR range
OSCAR painter’s tape — prevents paint bleed and removes easily


Mistake 5: Neglecting drying time and the second coat

What happens:
The color shifts, streaks appear, and cracks may form.

How to do it correctly:
Apply the second coat only after the first one has fully dried — from 2 to 24 hours depending on the type of paint.

Drying times according to OSCAR:
🕒 Water-based emulsion — 2–4 hours
🕒 Acrylic — 4-6 hours
🕒 Alkyd enamel — up to 12 hours
🕒 Varnish and stain — 12-24 hours


What to remember

✅ Preparation is half the battle.
✅ Don 't skimp on tools
✅ Consider the conditions and the surface
✅ Use paints that are suitable for their intended purpose
✅ Follow the instructions

🎨 Everything you need is in one place:

  • Paints, enamels, primers
  • Rollers, tapes, films
  • Solvents and aerosols
    — You will find all this in the catalog OSCAR
