【Construction Example 17】Renovation of the apartment building's exterior with a luxurious sandstone-like exterior material.
The handrail walls (approximately 2,300m2) of an 11-story large-scale apartment complex have been renovated with a luxurious appearance using "multicolored sagan" that resembles natural sandstone.
We would like to introduce an example of the renovation of the existing sprayed tile finish handrail walls of a large 11-story apartment complex, using the "Multicolor Sagan" in a natural sandstone (split surface) style. 【Property】 [Renovation] Certain Apartment Complex ◇ Construction Date: September 2007 ◇ Construction Area: 2,309 m² ◇ Substrate: PC structure sprayed tile 【Customer's Issues and Requests】 ◆ The exterior walls of the apartment, completed in 1984 (over 20 years old), need to be updated to a new, brighter exterior image. ◆ A durable, weather-resistant, long-lasting exterior material is desired. ◆ We want a more luxurious appearance than standard paint. 【Adoption Process】 ◇ The decision was made to adopt the material due to its high weather resistance, long-lasting beauty, and the luxurious appearance of the natural sandstone design compared to standard paint. 【Selection Points】 ◆ Natural sandstone cannot be used as exterior wall material due to dust contamination and the growth of mold and moss, but Hamacast's "Multicolor Sagan" can be used for exterior walls due to its stain resistance and high weather resistance. ◆ The design quality surpasses that of natural stone. ◆ Excellent weather resistance and durability, with a long-lasting exterior finish material that comes with a 20-year warranty.
