Paint Peeling, Wall Cracks, and Tile Gaps 2026: Real Causes and Permanent Solutions to Eliminate These Problems

Introduction: Why Do Most Saudi Homes Suffer from Paint and Wall Problems?

Many homeowners in Saudi Arabia suffer from recurring problems after construction and finishing, most notably paint peeling, wall cracks, and gaps between tiles from which insects and ants emerge. These problems are not just aesthetic defects but may indicate deeper issues in construction or execution. The hot and dry weather in Saudi Arabia puts additional pressure on walls and paints, especially with large temperature differences between day and night causing continuous expansion and contraction of materials.

In this comprehensive guide, we detail the causes of each problem and treatment methods along with preventive architectural solutions that prevent them from occurring in the first place. We will also learn about the best types of paints and materials available in the Saudi market.

First: Paint Peeling - The Real Causes

Paint peeling is one of the most annoying problems for homeowners, where paint begins to bubble, then crack, and finally falls off as flakes. There are several main reasons for this problem.

Moisture and Water Leakage

Moisture is the first and most common cause of paint peeling. When water seeps into the wall whether from internal pipes, roofs, or soil, it weakens the paint adhesion to the wall. Paint begins to bubble first, then cracks and peels. This problem appears clearly on bathroom ceilings, exterior walls, and humid areas in the home.

Not Preparing Walls Before Painting

Neglecting to clean walls from dust before painting significantly weakens paint adhesion. Also, not using primer or base before final painting causes paint failure to adhere to the surface. Not filling cracks, leveling walls, and sanding putty are all execution errors that lead to paint peeling after a short period.

Applying Plastic Paint Over Oil Paint

A common mistake is applying latex or plastic paint over an old oil paint layer. These two types are not compatible, and the result is peeling of the new layer after a short period. Old oil paint must always be removed or appropriate primer used before new painting.

Using Poor Quality Paints

Cheap and unknown source paints peel quickly and change colors. These paints lack sufficient binding materials that ensure good adhesion to the wall. Some painters may use luxury product containers and refill them with poor materials, so make sure to buy from authorized dealers.

Not Letting Layers Dry Completely

Applying a second coat before the first coat dries completely causes cracks and peeling in the paint. Each layer needs sufficient time to dry before applying the next layer, and this time varies depending on paint type and weather conditions.

Excessive Dryness and High Heat

Conversely, extreme dryness and direct exposure to scorching sunlight causes paint cracking and peeling, especially on exterior facades. Heat causes paint to dry too quickly before it adheres well to the surface.

Paint Peeling Treatment Step by Step

To properly treat paint peeling, the following steps must be followed carefully.

Step One: Treat the Root Cause

Before starting any repair, the cause of peeling must be identified and treated. If the cause is water leakage, it must be fixed first. If the cause is moisture, the wall must be completely dried and dehumidifiers used. Surface treatment without treating the cause will make the problem return again.

Step Two: Prepare the Work Area

Cover the floor with cloth or plastic pieces to protect it from falling flakes and paint. Use adhesive tape to hide door edges, electrical outlets, and windows. Wear protective glasses, gloves, and mask to protect yourself.

Step Three: Remove Damaged Paint

Use putty knife or scraping tool to remove all peeling paint. Work in vertical and horizontal movements and make sure to remove all parts that are not well adhered. Do not stop at the visible boundaries of peeling but remove any paint that appears weakly adhered.

Step Four: Sanding and Smoothing

After removing damaged paint, use sandpaper to smooth the surface and remove any residue. The surface must be smooth and even before the next stage. Wipe the resulting dust with a damp sponge.

Step Five: Fill Cracks and Holes

Use wall putty to fill any cracks or holes in the wall. Apply thin layers and let them dry completely between each layer. Some types of putty need two hours to dry and some four hours or more.

Step Six: Sand the Putty

After the putty dries completely, use fine sandpaper to smooth it and make it even with the rest of the wall. Clean the surface from dust.

Step Seven: Apply Primer

Primer is an essential step that should not be skipped. Primer ensures good paint adhesion and prevents cracks and bubbles from appearing in the future. Choose primer appropriate for surface type and paint type you will use. For humid areas, use moisture resistant primer.

Step Eight: Final Painting

Choose high quality paint from a known brand. Put paint in a tray and use roller for large surfaces and brush for narrow areas. Apply at least two coats and let each coat dry completely before the next coat.

Second: Wall Cracks - Types and Causes

Wall cracks are a common problem whose severity varies depending on type and size. Some cracks are superficial and easy to treat, and some indicate serious structural problems.

Expansion Cracks

These occur due to concrete expansion from high heat. They usually appear between concrete elements and walls and in areas exposed to sun. These cracks are common and not dangerous and can be treated with putty and paint.

Shrinkage Cracks

These occur due to concrete shrinkage after pouring as a result of cold or rapid drying. They appear as small hairline cracks on the surface. They can be treated the same way as expansion cracks and usually do not return after treatment.

45-Degree Angle Cracks

These cracks are more dangerous and usually indicate structural problems. They may be due to settlement in foundation soil or increased loads on walls. They usually appear at door and window corners. They need evaluation by a specialized engineer.

Plaster and Whitewash Cracks

These affect the outer layer of the wall and cause paint to fall off. They result from not preparing the surface properly before plastering or using poor materials or exposure to heat and humidity. They can be treated by removing the damaged layer and replastering and painting.

Serious Structural Cracks

Deep and wide cracks appearing in columns or beams or that widen over time indicate serious structural problems. They may be due to earthquakes, soil settlement, or poor execution. They need immediate consultation with a structural engineer and may require building renovation.

Wall Crack Treatment

Treatment method varies depending on crack type and severity.

For Surface and Hairline Cracks

Clean the crack from dust and dirt. Widen the crack slightly using putty knife to make it easier to fill. Fill the crack with wall putty and let it dry. Use sandpaper to smooth the surface then apply primer and paint.

For Medium Cracks

Use Sika material to treat cracks as it increases concrete surface strength. Fiberglass tape can also be used to strengthen the area before putty. For cracks between brick and concrete, use flexible putty that accommodates movement.

For Structural Cracks

Call a specialized engineer to evaluate the situation. Treatment may require using aluminum strips or carbon fiber to strengthen the area. In severe cases, replacing parts of concrete or iron may be necessary. Do not try to repair structural cracks yourself.

Third: Tile Gaps - Insect and Ant Problem

Gaps between ceramic and porcelain tiles are an annoying problem that causes insects and ants to enter and dirt and bacteria to accumulate. This problem occurs for several reasons.

Causes of Gap Appearance

Weakness of grouting material used between tiles makes it erode over time. Using traditional white cement in grouting makes it prone to crumbling and separation. Frequent cleaning with strong chemicals weakens grouting material. Expansion and contraction due to temperature changes causes grouting to separate from tiles.

Danger of Gaps

Gaps between tiles become passages for ants and other insects to enter from under the floor. White ants especially can reach the building through these gaps and cause significant damage. Moisture and dirt also accumulate in these gaps and become a fertile environment for bacteria and mold.

Solutions for Filling Tile Gaps

There are several methods to fill gaps between tiles depending on gap type and location.

Re-grouting with White Cement

The traditional method is to remove old damaged grouting using a knife or sharp tool then refill joints with new white cement. Mix white cement with water until it becomes a coherent paste and fill gaps with it. Quickly wipe excess from ceramic before it dries.

Using Ready-Made Joint Filler

Ready-made filler for ceramic gaps is available in markets in easy-to-use tubes. This filler is water resistant and resistant to chemical cleaning materials. It has a fine tip that makes it easy to apply precisely in gaps. It dries and lasts for a long time.

Silicone for Wide Joints

For wide gaps in corners and around basins and bathtubs, silicone or flexible sealant is preferred. Silicone is water resistant and flexible to accommodate any movement. Suitable for joints up to 6 millimeters wide.

Ceramic Adhesive

Sold ready in different sizes and is water resistant. Suitable for walls exposed to moisture such as shower walls. There is an acrylic type that features non-slip properties.

Epoxy for Permanent Protection

Epoxy grouting is the strongest and most durable. Resistant to water, stains, and chemicals. Suitable for high-use areas. Its cost is higher but it lasts for many years without problems.

Ant Control Before Sealing

Before sealing gaps, make sure there are no ants or insects under tiles. Use specialized ant pesticide in gaps and leave it to work for several days. If there is white ant infestation, a specialized pest control company must be called.
