INSTALLATION GUIDE

Substrate Requirements:

Internal:

• Suitable surfaces: Plasterboard, MDF (dry areas only), compressed fibre cement sheeting, brick, or concrete

• Surface must be flat, clean, and dry

External:

• Suitable surfaces: Compressed cement sheeting, exterior-grade plywood, brick, or concrete

• Self-adhesive Brico panels not recommended outdoors

• Priming may be required for porous or dusty surfaces

Cutting:

• Utility knife: For straight cuts (score multiple times)

• Jigsaw or fine-toothed circular saw: For curves or high precision

• Always wear safety gear and support panels when cutting

Corners & Edges:

• No pre-formed corner trims included

• Installers typically:

  • Mitre cut at 45° for neat external corners

  • Use metal or colour-matched architectural trims

• Window and door openings: Cut panels to fit and finish with sealant or trim

Adhesive Recommendations:

For vertical applications, use bracing or painter’s tape to hold panels until adhesive sets.

Spacing & Grouting:

• Panels are typically butt-jointed for seamless look

• Grouting is not required

• Optional: use colour-matched flexible sealant between joints for water resistance or aesthetics (especially outdoors)

 

CARE & MAINTENANCE

• Cleaning:

  • Use soft cloth or sponge with mild detergent

  • Avoid high-pressure water jets (especially on joints)

  • Do not use abrasive scrubbers or acidic cleaners

• Outdoor maintenance:

  • Check joints annually and reseal if needed

  • Ensure proper drainage to avoid water pooling

• Repairs:

  • Individual panels can be removed and replaced if damaged

  • Use same adhesive and sealant type for replacements

 

TIPS & WARNINGS

• Do not use Brico range panels outdoors — tape adhesive may fail in moisture or UV exposure

• Always ensure substrate is level and structurally sound before installation

• For fireplace surrounds, do not install in direct contact with flame or high heat zones

• Store panels flat in a cool, dry space prior to install
