1. Product Description
The surface of concrete is very smooth. If it is roughened directly with cement slurry without treatment, the bonding will be poor and it will easily lead to peeling between the roughened layer and the concrete surface. ; If the concrete surface is roughened, the effect is good, but it is labor-intensive and time-consuming. 209 interface treatment agent is a gray solid powder, mainly used for interface treatment of concrete base plaster, and can also be used for surface treatment of large blocks. The surface of the base layer treated with the interface treatment agent can increase the adhesion of the cement mortar to the base layer, and has high water resistance, heat resistance, and freeze-thaw resistance, avoiding the phenomenon of plaster bulging, shelling, and falling off. This replaces the manual chiseling process, saves time and effort, and greatly improves the quality of the project. It has been determined by comparison that under the same conditions, the bonding force between the base layer and cement mortar treated with 209 interface treatment agent can be increased by 45-65%.
2. Instructions for use
1. 209 interface treatment agent is a gray granular powder. When using it, you only need to add water to make it into a thick paste (no dough will be left). ), the water-cement ratio is about 1:4. At the same time, floating dust, oil stains, etc. on the base layer must be removed.
2. In summer, when the temperature is high, dry walls should be moistened with water before construction.
3. The mixed interface agent can be directly applied with an iron trowel to a thickness of about 2-3mm.
4. After the interface agent is applied to the wall for about 15-20 minutes (depending on the temperature), the interface agent can be plastered after the interface agent is slightly slurried.
5. The dosage per square meter is about 2-2.5kg, and the liquid: material to dust ratio is 0.3-0.5.
3. Packaging and Storage
This product is packed in composite woven bags lined with plastic bags, each bag is 50±0.5kg. Liquid packaging is 25kg per barrel. The storage period of this product is 6 months, and it should be protected from rain and moisture during storage.
Product name | Product performance and characteristics |
209 interface agent (type A, high efficiency) | This product appears as gray solid powder. Mainly used for interface treatment of new and old concrete base plastering. The surface of the base layer treated with this interface agent becomes rough, which can increase the bonding force between the cement mortar and the base layer and prevent the plaster layer from hollowing out, thereby replacing the manual chiseling process and saving time and labor. |
209 interface agent (type B, ordinary type) | This product has a gray solid powder appearance and is mainly used for interface treatment of damaged walls, floors, new and old concrete, and interface treatment of new concrete and lightweight block base plastering. The surface of the base layer treated with this interface agent becomes rough, which can increase the bonding force between the cement mortar and the base layer and avoid hollowing, shelling, cracking and leakage of the plaster layer. |
209 interface agent (type C, air-entrained block) | This product is a special�It is specially developed for interface treatment of fly ash blocks, sand aerated blocks, aerated concrete, perlite and porous water-absorbent material base layers to prevent the plaster layer from hollowing out. This product has good water retention and does not require wet water on the surface of porous wall materials. It has good construction properties and has good bonding and adhesion with the base layer. It has excellent thermal shock resistance and excellent anti-aging properties. performance. Long service life; water-resistant, freeze-thaw resistant, and high-temperature resistant. |
