1. Assess the Wall Condition

• Identify the source of moisture (e.g. rising damp, leaks) and fix it first.
• Aqualock can manage moisture, but cannot stop active water ingress like leaking pipes or
  unsealed cracks.

2. Clean the Surface

• Remove all loose paint, dust, dirt, grease, or biological growth (algae, mold, mildew).
• Use a biocide wash or fungicidal treatment if mold or mildew is present.
• If efflorescence (white salt deposits) is visible, brush it off with a stiff brush or sponge using
  warm water and allow to dry.

3. Repair Damages

• Fill any cracks, holes, or degraded areas with a compatible repair mortar or filler.
• For large or structural cracks, use a flexible filler or cementitious repair compound.

4. Assess Porosity & Surface Type

• Highly absorbent or powdery surfaces (e.g. old plaster, sandstone) should be stabilized using a
  primer.
• On very smooth surfaces, lightly sand or etch to promote adhesion.

5. Damp Tolerance

• Surface can be slightly damp—no need to wait for it to dry completely.
• But no standing water or active seepage should be present.

6. Primer

• Apply 1 coat of Polycolor Elastomeric Wall Primer

7. Mask & Protect

• Mask nearby surfaces (windows, trim, floors).
• Protect from rain or direct water contact during and just after application.
