ข่าว บริษัท เกี่ยวกับ Mildew-Resistant Sealants for Thailand Hotel Refurbishments

Thailand has a tropical monsoon climate. It is hot and humid all year round. The average relative humidity is 75% to 85%. For hotels in Thailand, wall mold is a common problem during refurbishments.

After the pandemic, more and more hotels in Thailand are renovating. They want to meet SHA+ hotel hygiene standards. They also want to improve guests’ experience. But many hotels use low-quality sealants. These sealants cause mold to come back soon after renovation. This increases maintenance costs.

This article explains why mildew-resistant sealants are important for Thailand hotel refurbishments. It tells you how to choose and use them. This helps hotels keep walls clean and mold-free in high humidity.

Thailand’s climate is very humid. From May to October, the rainy season, humidity can reach over 90%. Walls easily get damp. Damp walls are the perfect place for mold to grow.

Hotels have more mold risks. Rooms are occupied very often. Bathrooms produce a lot of steam. Air conditioners may leak water. If wall gaps are not sealed well, moisture gets in. This makes mold grow faster.

Mold is bad for hotel hygiene. It fails SHA+ hotel certification. SHA+ is a strict hygiene standard for Thailand hotels. Hotels with mold may need to fix problems. This hurts their reputation.

Mold also costs hotels money. Moldy walls need frequent cleaning and renovation. This shortens the life of walls. Low-quality sealants make mold come back in 3 to 6 months. Hotels waste money on repeated renovations.

Guests care a lot about hotel hygiene. Moldy walls make guests unhappy. This lowers OTA scores. It also makes hotels less competitive, especially luxury resorts.

Ordinary sealants do not work well in high humidity. They dry slowly and do not stick well. They cannot stop moisture from getting in. This leads to mold.

Many hotels have large-scale renovations. They may have hundreds of rooms. It is hard to keep sealant performance the same in all areas. Some areas may have mold while others do not.

Some mildew-resistant sealants only work for a short time. They cannot last 2 to 3 years, which is the usual renovation cycle for hotels. This means hotels have to renovate again soon.

Mildew-resistant sealants have special anti-mold ingredients. They meet ASTM G21 mold resistance standards. These ingredients stop mold from growing, not just cover it up. This works well in Thailand’s high humidity.

These sealants also seal gaps well. They stop moisture from getting into walls. They can stand hot and humid conditions. They do not get moldy themselves. For example, DOWSIL™ 818 mildew-resistant sealant is a good choice for this purpose.

Consistency means the same performance everywhere. For large hotel renovations, all sealants should work the same. They should dry at the same speed. They should stick well and stop mold equally.

Consistency also means long-lasting performance. The sealant should work well for 2 to 5 years. It should not fail in some areas. This stops mold from spreading and reduces maintenance.

Easy application is also part of consistency. The sealant should be easy to use. It should look smooth after application. This keeps the hotel’s decoration looking good.

Ordinary sealants have no anti-mold ingredients. They get moldy in 1 to 3 months in high humidity. Mildew-resistant sealants stop mold for years. They are better for hotels.

Ordinary sealants crack and fall off in high humidity. They cannot seal gaps well. Mildew-resistant sealants can stand hot and humid weather. They do not crack or fall off easily.

Ordinary sealants are cheap at first. But they need to be replaced often. This costs more money in the long run. Mildew-resistant sealants cost more at first. But they last longer. They save hotels money on maintenance.

First, check the mold resistance level. Choose sealants that meet ASTM G21 Level 0. This means they stop mold growth completely in high humidity.

Second, check heat and humidity resistance. The sealant should pass aging tests. It should not crack or get moldy after 720 hours in 40°C and 90% humidity. This fits Thailand’s climate.

Third, check adhesion and flexibility. It should stick well to tiles, gypsum boards and aluminum. The elongation at break should be over 300%. This stops it from cracking when walls move a little.

Fourth, check environmental friendliness. It should have low VOC (≤4%). It should not have a strong smell. This meets SHA+ certification requirements.

Bathrooms and kitchens need water-resistant and easy-to-clean mildew-resistant silicone sealants. They can stand frequent steam and water.

Guest room walls and window gaps need sealants that are both anti-mold and decorative. They should look smooth and not ruin the wall’s appearance.

Exterior walls and terraces need weather-resistant sealants. They should stand strong sunlight and high humidity. They should not age or crack easily.

Mistake 1: Choosing cheap sealants. These have low mold resistance. They cause mold to come back soon. This increases maintenance costs.

Mistake 2: Confusing “surface anti-mold" with “long-term anti-mold". Some sealants only stop mold on the surface. They do not work in Thailand’s long-term high humidity.

Mistake 3: Ignoring application ease. Some sealants are hard to use. They dry too fast or too slow. This affects the sealing effect.

Before application, clean the wall gaps. Remove dust, moisture and old sealant. Make sure the surface is dry (humidity ≤60%). This helps the sealant stick better.

Apply the sealant in a thickness of 3 to 5mm. Fill the gaps completely. Do not leave bubbles or empty spaces. Smooth the sealant right after application. This makes it look good and seal well.

After application, keep the area ventilated. Do not let it get too humid or sunny. Let the sealant dry evenly. Follow the product’s drying time. Do not touch or get it wet too soon.

For large hotel renovations, use the same batch of sealant. Use the same application standards. Hire professional workers. This ensures the same effect in all areas.

Case 1: A high-end SHA+ hotel in Bangkok renovated its guest rooms and bathrooms. It used mildew-resistant sealants that meet ASTM G21 Level 0. After 18 months, there is no mold. Guests are 20% more satisfied. The hotel passed all hygiene checks.

Case 2: A resort in Phuket renovated its exterior walls. It used weather-resistant mildew-resistant sealants. These sealants solved the old mold and cracking problems. Maintenance costs dropped by 30%. The wall renovation cycle extended to 4 years.

A good example is the Andatel Grande Patong Phuket. It spent 25-30 million THB on bathroom renovations across 122 rooms. It used mold-resistant materials to prevent mold in the humid coastal environment. This made it a top choice for hygiene-conscious guests.

These cases show that good mildew-resistant sealants and correct application keep walls clean. They save hotels money and improve their reputation.

Thailand’s high humidity makes mold a big problem for hotel walls. During renovations, mildew-resistant sealants are key. They determine if walls stay clean and consistent.

Choosing the right sealant and applying it correctly helps hotels meet SHA+ standards. It improves guests’ experience and reduces maintenance costs. It also makes hotels more competitive.

As more hotels in Thailand renovate, mildew-resistant sealants will become more important. They will help hotels keep walls mold-free for years.
