Have you ever experienced this? When buying a new house or condo, everything looks perfect. The walls are smooth without cracks, and there are no leaks. But after a few years, problems start to appear, such as cracks in the walls, water dripping from the ceiling, peeling paint, or sagging floors. These issues are common problems homeowners face when using their properties. Today, “Crocodile,” a comprehensive construction innovation company, is here to discuss the most frequent home problems encountered by Thais. These issues arise not only from the deterioration of materials but also from improper installation and low-quality materials. We will also provide expert solutions to help protect your home for long-term comfort.

·Cracked Concrete Surfaces: A Problem Not to Be Overlooked

Cracked concrete surfaces can arise from various causes, including material shrinkage, the use of low-quality materials, or improper usage. Cracks in concrete surfaces come in different forms. Non-hazardous cracks that should be repaired include spider cracks, uneven surfaces, and peeling surfaces caused by concrete shrinkage or excessive load. In contrast, hazardous cracks that affect structural integrity include cracks wider than 5 mm or diagonal cracks, which may result from foundation or column settlement. A qualified engineer should analyze these issues and propose proper repair methods.

For cracks in concrete surfaces, such as spider cracks and uneven surfaces, Crocodile recommends the product Crocodile Floor Smooth Patch, a thin-layer concrete surface repair mortar with high adhesion that bonds excellently to existing surfaces and can be applied on sloped areas without flowing.

·Cracked Walls, Mold Growth, and Peeling Paint

Mold issues arise from accumulated moisture, primarily due to leaks, rain, poor ventilation, and lack of sunlight, which can easily lead to mold growth in rooms. Peeling paint may result from aging, exposure to sun, rain, moisture, or improper painting techniques using low-quality paint.

To eliminate mold, scrub with a brush and wipe with alcohol, suitable for newly formed mold that is not deeply embedded, or use a mold and moss remover for walls. Importantly, address the root cause by repairing leaks, applying high-quality waterproofing before painting, and improving ventilation by opening doors and windows or installing exhaust fans. For peeling paint, start by scraping off all loose paint with a scraper, sanding the wall to smooth it, cleaning the wall with a damp sponge, allowing it to dry completely, and then following the steps from surface preparation to topcoat application.

Crocodile recommends the product Crocodile M-Kill, a mold and moss remover that is safe for users, helps reduce moisture on plaster surfaces, and minimizes the chances of mold and moss recurring in the same area. It can be used on all surfaces and smooths the wall with Crocodile Skim Coat Smooth, a fine-textured finishing plaster that ensures a uniform, smooth, and durable wall surface. Additionally, use Dust Primer, a water-based primer for old plaster that prevents dust, or Ultimate Primer, a versatile water-based primer for both interior and exterior that penetrates well into surfaces, enhancing adhesion between the topcoat and the wall. Choose high-quality paint products for interior wall decoration, such as Crocodile Easy Clean Premium, an ultra-premium emulsion paint that is easy to clean and reduces dirt adhesion on walls, or Crocodile EcoSphere Premium, a 100% natural limestone paint that is safe for residents and environmentally friendly, as well as decorative paints for interior use like Crocodile Stone Decor, which creates a natural stone pattern, and Crocodile Metallic Loft, a metallic decorative paint with a loft pattern.

Wall cracks can arise from various causes, including material shrinkage, the use of low-quality materials, or improper usage. Cracks in walls come in different forms, each with varying severity. Non-hazardous cracks that should be repaired include small cracks from plaster and cracks at joints with frames caused by the expansion and contraction of different materials. In contrast, hazardous cracks that affect structural integrity include vertical cracks in the middle of walls caused by sagging beams, 45-degree diagonal cracks from uneven settling of the house, and U-shaped cracks under beams, which are very dangerous and may lead to structural collapse and leaning walls at risk of falling. A qualified engineer should analyze these issues and propose proper repair methods.

For small wall cracks, repairs can be made using high-quality crack repair products. Crocodile recommends Crocodile Wall Putty, a ready-to-use acrylic filler for cracks that dries quickly, is easy to sand, and can be painted over. It can be used on various materials, and for cracks at joints with frames, use Crocodile Acrylic Seal Plus, a special-grade acrylic sealant that is flexible and contains anti-mold agents.

·Loose, Warped, or Exploding Tiles: Hidden Problems Beneath the Floor

Tile warping occurs when tiles push against each other and crack, which may happen in isolated areas or across a wide area. Key causes include substandard tile installation, not mixing adhesive according to the specified ratio on the bag, not applying adhesive evenly across the tile, or using the wrong type of mortar, such as using black mortar for tiling or applying it in a dry mix. Exposure to sunlight or hot weather during the day can cause tiles to expand, and moisture can seep under the tiles if waterproofing is not applied before tiling.

The first step in addressing this issue is to inspect the problem. If it is widespread, all tiles should be removed and reinstalled using standard adhesive. For durable tile installation, Crocodile recommends Crocodile Green Adhesive, the number one-selling adhesive for granite and ceramic tiles, which is fine-textured, easy to work with, and can be used for both floor and wall tiles inside and outside buildings without soaking the tiles in water beforehand. For areas with temperature fluctuations or continuous use under heavy loads, Crocodile recommends Crocodile Gold Adhesive, which is flexible and accommodates tile expansion and contraction.

·Leaking Roofs and Water Seeping Through Joints: Common Problems During the Rainy Season

Roof leaks are another common issue, especially during the rainy season. The main causes include substandard roofing, materials deteriorating from exposure to sun, wind, and rain. Signs of a leaking roof include water stains on ceilings or walls, and water droplets or moisture on walls or ceilings when it rains.

Start addressing the problem by inspecting various points in the house to identify any leaks or cracks causing water seepage. If you find cracked or damaged tiles over a wide area, they should be removed and replaced, along with applying waterproofing to prevent long-term leaks, especially at joints and vulnerable points. In cases of old, decayed roofs, metal sheets can be installed over them, ensuring to choose high-quality products. If the leak is large or the roof is high, it is advisable to call an experienced technician. Importantly, roofs should be inspected regularly at least once or twice a year, especially before the rainy season, to prevent long-term issues.

Crocodile recommends using Crocodile Poly U Seal, a polyurethane sealant that is highly flexible (over 700%) and weather-resistant, suitable for both indoor and outdoor applications. It dries quickly and is ideal for sealing roof joints, extension joints, and roof bolt heads. Then, apply Crocodile Roof Shield, a high-quality super acrylic waterproofing product for roofs and terraces, which is a ready-to-use acrylic waterproofing solution that is highly flexible, covers hairline cracks, and is resistant to rain and UV rays, lasting up to 8 years* and can withstand standing water for more than 180 days** (results from Crocodile laboratory tests **when used according to the company's recommendations).

·Water Seeping from Upstairs Bathrooms to Downstairs: A Major Problem for Two-Story Homes

Water leaking from upstairs bathrooms to downstairs is another issue that many homeowners find frustrating. The main causes include improper drilling of water pipes, lack of waterproofing before tiling, or improper application, and the deterioration of grout over time. Start by cleaning the floor to ensure it is dry and free of dirt, then apply high-quality waterproof cement over the entire floor in two coats, wait for it to dry, and then retile using high-quality cement adhesive. Finally, apply high-quality grout, such as epoxy grout, which provides better adhesion than cement-based grout, is more durable, and resistant to scrubbing, cleaning, and chemical corrosion.

Crocodile recommends Crocodile EcoShield, a waterproofing product for bathrooms before tiling, which has high adhesion and prevents water seepage, along with Crocodile Green Adhesive, which has high adhesion and ensures tiles stick firmly, and the ultimate Crocodile Epoxy Plus Adhesive and Grout, which is resistant to chemical and acid corrosion from various substances, such as bathroom cleaners, caustic soda, and pipe cleaners. The most important thing is to choose high-quality products at every step, from waterproof cement to adhesive and grout, to extend the lifespan and prevent recurring issues.
