"FB Protect" is a protective coating material that suppresses carbonation by protecting the inside of the foundation concrete, thereby enhancing durability and extending its lifespan. By applying it immediately after demolding, it allows for the continuation of the hydration reaction and enables the densification of the concrete. The application process is simple, requiring only the mixing of two components and painting with a wool roller, so no specialized skills are necessary. Currently, we are distributing materials that include test data, which can be viewed via PDF download. 【Features】 ■ Exhibits crack-following ability ■ Confirmed carbonation suppression effect through comparative tests with and without surface coating (according to our research) ■ Easy to apply with a simple process ■ Contributes to the longevity of residential foundations ★ If you would like a sample, please apply through the contact form.

The "House Shoes Series" is a protective method for residential foundations that excels in weather resistance, low contamination, and crack-following properties. It combines pre-mixed elastic polymer cement mortar with water-based elastic acrylic silicone paint, developed by our company. It prevents fine cracks and contamination of the foundation surface, which have been problematic in residential foundation finishing. It can suppress the neutralization of foundation concrete and enhance the durability of the foundation. 【Features】 ■ Combines pre-mixed elastic polymer cement mortar with water-based elastic acrylic silicone paint ■ Excellent weather resistance, low contamination, and crack-following properties ■ Prevents fine cracks and contamination of the foundation surface ■ Suppresses the neutralization of foundation concrete ■ Enhances the durability of the foundation *For more details, please refer to the PDF materials or feel free to contact us.

As concrete undergoes carbonation, the protective layer around the rebar inside deteriorates, causing the rebar to rust. The rusted rebar expands, leading to cracks in the concrete. Water and carbon dioxide can enter through these cracks, accelerating the deterioration. 【Conditions Favoring Carbonation】 ■ High carbon dioxide concentration ■ Humidity between 50% and 70% ■ High temperatures 【Suggestions】 ■ House shoes ■ FB Protect A protective coating material that suppresses carbonation by protecting the inner side of the foundation concrete, which can be expected to improve durability and extend lifespan.
