Q2：外牆磁磚掉落、剝落，一定要全面打除嗎？

不一定。

• 若磁磚大面積空鼓、隆起 → 須全面打除。

• 若局部空鼓且基層穩定 → 局部打除與介面強化 即可。

• 若磁磚牢固無異常 → 可直接覆塗仿石塗料系統，無需拆除。
  ※ 仿石塗料與無機塗層為老屋翻新的主流覆層系統。

Q3：老屋拉皮會改善壁癌與滲水嗎？

會，但前提是要「先處理漏水源」。
外牆拉皮只能改善外層保護，若漏水源來自：

• 屋頂

• 窗框收邊

• 陽台排水

• 管道間滲水

必須同步整修，否則壁癌仍會反覆出現。

---

Q4：外牆拉皮與防水工程有什麼不同？需要一起做嗎？

不同，但應該一起做。

• 防水工程：停止水分滲入，屬於保護層。

• 外牆拉皮：外觀與耐候保護，屬於飾面層。

建議流程：
防水 → 介面強化 → 仿石／無機塗料 → 透明防護層

---

Q5：拉皮會影響住戶正常生活嗎？需要搬家嗎？

一般不需要搬家。
塗料型拉皮屬於輕量化、無震動、低噪音工法，
施工期間最多影響為：

• 外牆架設鷹架

• 施工時段低噪音

• 部分陽台可能有防落網

住戶大多可照常生活。

---

Q6：老屋拉皮的費用怎麼計算？可以自己估算嗎？

基本公式：
外牆面積㎡ × 單價（依工法） = 預估費用

常見單價（每坪約）

• 仿石塗料：NT$2,000～3,500

• 無機塗料系統：NT$3,000～4,500

• 石材貼面：NT$8,000～12,000

• 防水塗料：NT$2,000～3,000

若想自行估算，你只需量：

• 建築高度 × 外牆寬度
  再扣除窗戶與開口，即可得出概估面積。

---

Q7：老屋拉皮與重建（危老／都更）要怎麼選？

適合拉皮：

• 結構安全無虞

• 局部損壞、外觀老化

• 預算有限、想快速更新外觀

適合重建：

• 柱樑爆裂、鋼筋嚴重鏽蝕

• 耐震能力不足

• 想升級到現代坪效、車位與設備

簡單一句話：
➡ 能補強就拉皮，補強無效就重建。

---

Q8：拉皮後可以選擇任何顏色或風格嗎？

可以。
仿石塗料、藝術塗料、多彩塗層皆可：

• 模擬天然石材

• 做肌理紋理（砂岩、花崗岩）

• 無接縫、全塊面設計

• 客製顏色與粒徑

若想大幅改善老屋外觀，仿石塗料是變化最多、最自然的方式。

---

Q9：塗料會不會褪色？耐久度如何？

華彩塗料採用：

• 耐候型樹脂

• 無機礦物塗料

• 透明抗 UV 防護層

比傳統外牆漆高出 3～5 倍耐候性。
在台灣高熱潮濕氣候下也不易褪色，壽命可達 15～20 年。

---

Q10：老屋拉皮可以申請補助嗎？

可以，各縣市皆有補助，例如：

• 台北市：最高 800 萬

• 新北市：最高 1200 萬

• 高雄市：每㎡ 3500 元，最高 15 萬

補助內容通常包含：

Projects	Stone Paint	Multi-Color Paint
Stone Imitation Effect	Rough, three-dimensional, resembling granite	Delicate, colorful, high-grade stone, customized texture Simulates the subtle color variations of natural stone
Composition	Mostly made from a combination of natural colored sand and resin	Utilizes water-based resin technology, using water as the dispersion medium Particles float within the coating, creating a natural stone-like texture during spraying
Application Method	Multiple coats, a relatively long construction period, and labor-intensive process make it unsuitable for projects with tight deadlines. If local repairs or color changes are required, achieving an identical texture and color is difficult. Maintaining overall consistency is difficult for future maintenance or repairs.	Using "colorful particle dispersion technology," a multi-color patterned effect is created in a single application. Spraying allows for one-step application, resulting in high efficiency and easy maintenance.
Texture	Sandy, three-dimensional texture, relatively rough feel Rough texture, not suitable for all spaces The surface has sandy grains. While similar to stone, it is not suitable for indoor use or areas requiring a smooth feel. It easily traps dust and is difficult to clean without a surface treatment.	Smooth or fine grains, can be three-dimensional or flat, with high self-cleaning properties.
Environmental performance	Depending on the product, available in water-based or oil-based forms Using water as the primary solvent, this low-VOC, environmentally friendly water-based product is virtually odorless and meets green building material standards.	Using water as the main solvent, it is a low VOC, environmentally friendly water-based product with almost no odor, meeting green building material standards.

Can paint be applied in the bathroom?

Q: "Can the paint be applied to the bathroom?"
A: "Not necessarily, it depends on the construction area and substrate"

[Recommendation not to use]

Bathrooms without dry and wet separation (because it is easy to use detergent or shower gel to get into the bathroom when taking a bath, but often need to be repaired and maintained).

【Usable suggestions】

Equipment systems with heaters or windows that can keep the bathroom ventilated are only recommended for use in bathrooms with dry and wet separation, the "dry area" part

▲Dry and wet separated bathroom

Dry area: walls and ceilings of sinks, storage areas, toilets and other areas. (Please confirm your usage habits in dry areas before applying in areas where you will not be flushed with water or splashed with water.)

Wet area: The walls of areas such as shower rooms and bathtubs that are exposed to water for a long time.

Ceiling: Ventilation equipment needs to be installed, and the bathroom can be used if it is well ventilated.

Wash basins: Please avoid areas where water and cleaning products may be sprayed.

Toilet: It is not recommended to work nearby as water and detergent will be used to clean the toilet.

Bathtub/Shower Area: Neither is recommended.

Dry Rot Treatment Q&A: Understand and Eradicate It!

Dry rot (colloquially "wall cancer") is a common household problem in Taiwan, not only affecting aesthetics but also potentially harming your health. This Q&A condenses the essentials of dry rot treatment, helping you quickly grasp the solutions!

---

Q1: What is dry rot? Why do I have it at home?

Dry rot, scientifically known as "efflorescence," is the crystallization of calcium carbonate formed when moisture inside walls reacts with air. The main causes are excessive humidity, water leaks, structural cracks, or poor ventilation.

---

Q2: Besides being unsightly, are there other issues with dry rot?

Absolutely! Dry rot can lead to mold growth (affecting respiratory health), wall damage, and even structural safety concerns, in addition to increasing repair costs.

---

Q3: Can I treat dry rot myself? What tools and materials do I need?

Minor dry rot can be self-treated, but for severe cases or if you can't find the source of the leak, it's advisable to seek professional help.

Tools: Scraper, wire brush, sandpaper, gloves, mask, safety glasses, paint brush/roller, bucket.

Materials: Dry rot remover, waterproof primer, putty, moisture-proof/alkali-resistant cement paint/latex paint.

---

Q4: What are the steps to treat dry rot?

1. Identify and fix the source of the leak: This is the most crucial first step.

2. Scrape off loose parts: Thoroughly scrape off old paint and dry rot crystals.

3. Clean the wall: Brush off dust and ensure the wall is dry.

4. Apply dry rot remover: Follow product instructions.

5. Apply waterproof primer: Blocks moisture, two coats recommended.

6. Patch with putty: Fill cracks, sand smooth.

7. Apply moisture-proof topcoat: Protects the wall, two coats recommended.

Q6: What if the dry rot is severe, or I can't find the leak source?

If the dry rot is severe or you can't pinpoint the leak's origin, it's strongly recommended to seek assistance from a professional leak detection specialist or dry rot treatment contractor. They can accurately locate the leak and provide a more comprehensive solution, preventing you from investing time and money without resolving the issue.

The advantages of exterior wall lifting include improving the beauty and versatility of the building's exterior walls, good waterproofness, good self-cleaning, resistance to wind and rain erosion, blocking ultraviolet rays, improving the impact of environmental pollution on buildings, extending the service life of the building, facilitating future maintenance and repair work, and diversified building materials can create different architectural styles, enhance the value of the building, and increase economic benefits.

Exterior wall resurfacing is a type of exterior wall construction method that improves the appearance of a building, increases protection and durability, and increases the service life of the building. It does this by adding additional building materials such as paint, stone, metal, film, tiles, etc. to the exterior wall surface of the building to cover the original exterior wall surface and enhance building protection.

It can be applied to different materials, including tiles, glass, metal, etc.

Do tiles have to be removed during building exterior wall renovation?

What is a drip bar?

Drip edges are a kind of building material used outdoors. Because dust and dirt are easily generated on the building plane, after being washed by rainwater, it is a product derived from leaving water stains and dirt on the wall.

Drainage, discharge rainwater, and break the path that flows down the roof wall. After installation, the sewage is cut off by the clean water line, and cannot touch the wall to achieve anti-fouling, beautiful and waterproof effects.

Drip bar features

flowing down the roof and wall, and draining the rainwater.

scope of use

Installed at the junction of building facades and planes such as balconies, window frames, wall tops, roofs, and window eaves.

There are mainly the following items:

1. What is the area to be applied?

2. Color pattern selection?

3. Make an estimate quotation

4. Arrange the duration

5. Actual construction period For the implementation of other related projects, more details need to be discussed

Old house renovation/old house renovation/building exterior wall renovation/house repair

Buildings have been for a long time, and they are eroded by earthquakes, acid rain, and ultraviolet rays. There will be cracks, water leaks, tiles falling, moldy... and other problems on the walls. When carrying out external wall renovation, most of the current trends will be replaced with paint, and the cost difference is relatively better than that of large civil engineering projects (building material purchase, construction period).

There are also problems that will be extended in the future, and it is also convenient for repairing, reorganizing, and refurbishing. Whether it is a building/commercial space/Tiancuo/building/public building, Therefore, more and more people choose imitation stone paint for repairing, and the customization is also relatively rich. If you ask a designer to design the exterior or interior, you can achieve creative and aesthetic wall decoration at a simple cost.
