A Step-by-Step Wall Preparation Guide Before Painting Your House

A common mistake homeowners in Pakistan make is focusing 100% of their attention on the final paint color, while completely ignoring the wall preparation process.

In professional painting, 80% of the work is preparation, and only 20% is the actual topcoat application. If the wall base is weak, uneven, or dusty, even the most expensive premium paint will start bubbling and flaking off within months.

Here is the ultimate, step-by-step professional wall preparation guide recommended by our store experts:

Step 1: Deep Wall Scraping & Sanding

First, use a professional paint scraper to remove all old, loose, flaky, or damaged paint. Once scraped, sand the entire wall surface with coarse sandpaper (80 or 100 grit) to remove all dust, grease, and loose concrete plaster. Wipe the wall clean with a dry cloth.

Step 2: Undercoat Priming using Gobis Acrylic Primer

Many painters skip this step to save costs, which is a major mistake. Apply 1 coat of Gobis Acrylic Wall Primer or Gobis Water Primer. The primer penetrates deep into the concrete plaster, sealing all pores and creating a highly adhesive, uniform surface. Without primer, the wall will absorb the moisture from your final paint, leading to patchy colors and low paint coverage.

Step 3: Crack Filling & Leveling with Reliable Wall Putty

After the primer dries, it's time to smooth out the walls. Apply 2-3 coats of Reliable Wall Putty (Wall Putty / Lapi) using a steel trowel. Reliable Wall Putty provides an incredibly smooth, chalk-free, and super-durable white base that fills all hairline cracks and corrects plaster imperfections.

  • *Pro Tip:* Once the putty is dry, sand it gently with fine-grit sandpaper (150 or 220 grit) to achieve a buttery-smooth, luxury finish.
  • Step 4: Flawless Finishing with Brighto Emulsions

    With your wall perfectly primed and puttied, it is ready for the final show! Apply 2-3 coats of premium Brighto Matt Emulsion or Brighto Super Emulsion for a rich, velvety interior wall finish. Brighto's high-scrub formula is wash-resistant, stain-proof, and will stay beautiful for years to come.
