What is an interface agent? Is it essential to apply an interface agent during wall

Gypsum Interface agent, also known as interface treatment agent, It features strong penetrating power, fully penetrating the substrate surface to enhance adhesion between the plaster layer and the base. This improves bonding strength, prevents hollow spots between plaster mortar and the substrate, and is suitable for applications like interior/exterior wall puttying, concrete substrate plastering, concrete repair, and tile bonding. It boosts cement mortar's adhesion to the base, eliminating the need for roughening the substrate, and prevents hollow spots or detachment in plaster layers and tiles. Simply put, interface agents remove dust from original walls or surfaces after plaster removal, enhancing the bonding strength of subsequent leveling compounds like gypsum or putty. This ensures more uniform and durable wall finishes. In home renovations, wall surfaces cover extensive areas and significantly impact overall aesthetic outcomes. Among numerous wall finishing techniques, applying interface agents is one essential step.

Interface agents treat surfaces like concrete, aerated concrete, sand-lime bricks, and fly ash bricks, resolving issues like hollow spots, cracks, and peeling caused by high absorbency or smoothness. They enhance adhesion between new and old concrete, as well as between concrete and plaster mortar, during construction joints, beam/column reinforcement, and renovations of existing foundations. Interface agents replace processes like alkali washing for degreasing and manual roughening, boosting adhesion by over 10 times. They facilitate better installation of large tiles and slabs when used with interface coating methods or high-adhesion mortar. Interface agents also protect concrete and steel reinforcement surfaces against deterioration and corrosion. Their strong penetrating power allows deep penetration into material surfaces, serving as a moisture barrier for oil-based coatings and ensuring strong bonding with polyurethane coatings. High compressive strength: After 28 days of room-temperature curing, compressive strength testing reaches 31.1 MPa, eliminating cracks caused by low strength.
