A strong finish starts with a strong base. Before waterproofing, tile installation or self-leveling mortar construction, the substrate must be clean, dense and stable enough to support the next layer. When the surface is dusty, sandy or loose, coatings and mortars may struggle to bond properly.
CKS PRIMER Concrete Interface Strengthening Agent is designed for this exact preparation stage. It is a high-penetration bonding agent formulated with polymer emulsion and multifunctional additives to help seal, penetrate and reinforce loose substrates before the next construction process begins.
CKS PRIMER is a ready-to-use concrete interface strengthening agent for substrate reinforcement treatment. It is especially suitable for dusty floors, sandy walls, loose sand-cement walls and surfaces after old putty removal.
Its role is not to replace waterproofing or tile adhesive. Instead, it prepares weak or loose surfaces so that the following layer - such as waterproof coating, tile installation materials or self-leveling mortar - can be applied on a more stable interface.
Many waterproofing or tiling problems begin before the top layer is applied. If the substrate has loose sand, dust, powdering plaster or weak old putty residue, the next layer may not have a reliable surface to grip.
By improving surface density and reducing dusting, CKS PRIMER helps create a better foundation for subsequent construction. This makes it particularly useful for renovation projects, repair work and sites where the existing base is not ideal.
Helps control dust, fix sand and improve adhesion on weak surfaces.
Penetrates deeply into loose substrates to support internal reinforcement.
Helps improve substrate density before waterproofing, tiling or self-leveling work.
Helps seal porous, dusty or sandy surfaces during interface preparation.
Easy for applicators to use on site without complicated mixing steps.
CKS PRIMER can be used for interface reinforcement treatment on concrete, aerated concrete, plastering layers and loose sand-cement walls before waterproofing or tile installation.
It is also suitable for reinforcing loose substrates such as sandy walls, dusty floors and surfaces after old putty removal. For flooring projects, it can be used as part of interface preparation before self-leveling mortar construction.
The exact method should follow the latest CKS technical guidance and site conditions. As a practical workflow, the product can be positioned in the following preparation sequence:
| Step | Action | On-site Reminder |
|---|---|---|
| 1 | Inspect the substrate | Check whether the concrete, plaster, wall or floor is dusty, sandy, loose or powdering. |
| 2 | Remove unstable residues | Clean loose dust, sand, peeling putty and weak surface contamination before primer application. |
| 3 | Stir before use | Sedimentation or separation during storage is normal. Stir well before application. |
| 4 | Apply evenly to the surface | Ensure the primer reaches the weak interface and avoids untreated areas. Do not treat the primer as a final waterproofing layer. |
| 5 | Continue with the next system layer | After the surface is properly prepared according to site conditions, continue with waterproofing, tile installation or self-leveling mortar construction. |
Protect the product from direct sunlight, rain, freezing and impact. Keep the package intact and keep it away from fire sources.
Store CKS PRIMER in a cool, ventilated and dry place at a temperature of 5°C to 35°C. Sedimentation or separation during storage is normal; stir well before use.
Shelf life: 12 months from the date of manufacture when stored properly.
A reliable waterproofing or tile installation system begins with the substrate. CKS PRIMER helps seal, penetrate and reinforce dusty, sandy and loose surfaces, making it a practical preparation product before waterproofing, tile installation and self-leveling mortar construction.

CKS PRIMER is used for interface reinforcement treatment on concrete, aerated concrete, plastering layers and loose sand-cement walls before waterproofing, tile installation or self-leveling mortar construction.
Yes. It is suitable for reinforcing loose substrates such as sandy walls, dusty floors and surfaces after old putty removal.
No. CKS PRIMER is an interface strengthening and bonding agent. It is used before waterproofing or other construction layers, not as the final waterproofing layer itself.
Yes. CKS PRIMER is suitable for interface reinforcement treatment before tile installation when the substrate is concrete, aerated concrete, plastering layer or loose sand-cement wall.
Yes. It is ready to use and easy to apply. If sedimentation or separation appears during storage, stir well before use.
Store it in a cool, ventilated and dry place at 5°C to 35°C. Protect it from direct sunlight, rain, freezing, impact and fire sources. The shelf life is 12 months from the date of manufacture.
