Versatile 4-in-1 Mortar for Kitchen and Bathroom Walls

Yes. With strong bonding, 4-in-1 mortar can directly replace the interface mortar plus base plastering mortar process on ALC blocks, red bricks, concrete shear walls, and loose substrates. Clean the substrate and apply directly firm bonding, no hollowing or detachment saving one step, labor, and materials.

It can be used for wall leveling in kitchens and bathrooms, but not as waterproof mortar directly. It is suitable for wall leveling in dry and mildly humid areas. After application, a waterproof layer must be applied to achieve waterproofing. Relying on it alone for waterproofing may lead to leakage in long-term humid environments. For kitchen and bathroom floor waterproofing, use specialized waterproof mortar or waterproof coating.

Yes. For new-old wall joints, wall groove filling, and small pothole leveling, apply 4-in-1 mortar directly. Strong bonding and fast hardening effectively reduce joint cracking. For high anti-crack requirements, embed alkali-resistant mesh before applying mortar for better results.

Yes. For uneven walls, apply ten to twenty millimeters in one coat no repeated thin layers. If the designed thickness exceeds twenty millimeters, apply in two coats, with the second coat after the first sets, to avoid cracking. For crack-prone areas, embed alkali-resistant mesh.

Generally, the next step can proceed after one to two days, depending on weather and thickness. Under normal dry conditions, the mortar basically hardens within three to seven days. Before formal putty or tiling, cure for at least seven days to ensure full hardening, stable strength, and reduced moisture content otherwise hollowing or cracking may occur. During curing, avoid rain, direct sunlight, and frost.
