DPC Injection Fluid vs Cream

Why There Are Two Injection Types

Chemical DPC systems are supplied as either fluids or creams. 

Both aim to create a damp-proof course, but they behave differently inside masonry.

The correct choice depends on wall structure, risk level, and scope of work.

Fluid injection systems are chosen by contractors to guarantee nothing is missed and a confident warranty can be given. 

Cream injection systems are chosen for DIY applications.

DPC Cream Vs Fluid injection

Injection Cream Systems

Injection Cream Systems

Injection creams are higher-viscosity products that rely on slow diffusion through masonry.

They are commonly used where:

  • Walls are uniform and modern
  • Brickwork is single-skin or consistent
  • Job size is small or low-risk
  • Access is simple
  • DIY or light remedial work is being undertaken

Cream systems are typically selected for straightforward situations where conditions are predictable.

Injection Fluid Systems

Injection fluids are lower-viscosity products designed to move through masonry pore networks more readily.

They are typically selected where:

  • Walls are thicker or irregular
  • Masonry density varies
  • Older construction methods are present
  • Consistent lateral coverage is required
  • Long-term performance is prioritised
  • Professional warranty is critical
 
 

Fluid systems are commonly used in professional remedial and trade applications.

Choosing the Appropriate Method

The choice between fluid and cream should be based on:

• Wall construction and age

• Thickness and material variation

• Presence of voids or mixed masonry

• Risk tolerance for follow-up work

• Are you a professional contractor or DIY?
