Key benefits include:

• Blocks persistent mould, nicotine and water stains
• Prevents stains from bleeding through the decorative topcoat
• Adheres to walls, ceilings, plaster, wood, masonry, glass and glazed tiles
• Suitable for previously painted surfaces
• Can be applied by brush, roller or airless spray
• Touch dry in approximately 1–2 hours
• Suitable for interior and exterior decorating projects
• May be left as a white satin finish without an additional topcoat
• As a primer, it is ideal for preparing problem surfaces where standard paint may not provide sufficient coverage or long-term durability.

Why Do Stains Reappear Through Paint?

Standard decorative paint can be porous enough for persistent marks to return as the coating dries. Water stains and damp can leave discolouration or mineral deposits behind, while nicotine and smoke damage may leave oily residues and odours that are difficult to cover with ordinary paint.

A specialist stain-blocking primer creates a barrier between the affected surface area and the fresh decorative coating. This helps isolate the mark and prevents stains from bleeding through the finished paint.

Severe staining may remain faintly visible after the initial application. If the affected area is not completely covered, allow the first coat to dry overnight before adding a second full coat.

Aquashield’s Stain Block can be used on:

• Walls and ceilings
• Wood and plaster
• Cement, brick and masonry
• Glass and glazed ceramic tiles
• Previously painted surfaces
• Galvanised steel
• Copper and zinc
• Polycarbonate and hard PVC

What Can Aquashield’s Stain Block actually cover?

Use our Stain Block to isolate staining caused by:

• Black mould
• Damp and water damage
• Nicotine
• Crayon
• Marker pen
• Tannins

Aquashield Solutions Stain Block can be applied to previously painted surfaces. Simply clean the existing topcoat with sugar soap and remove any oil and grease or dirt residue before application.

At 20°C and 50% relative humidity, Aquashield Solutions Stain Block Primer is normally touch dry within 1–2 hours.

Severe or persistent stains may require two coats of stain blocker. If the mark remains visible, allow the initial coat to dry overnight before adding a second. The stain should be completely covered and the primer fully dry before decorating.
