From cold-wall survey to a TLICS specification
This guide focuses on the installation brief for a trowel-applied cork build-up. For the wider diagnosis and remedy choices, begin with the black-mould decision guide. TLICS means the trowel-able layered insulating cork system route; DECO 00 FINO is a product that may be used within the specified assembly.
What to record before installation
- Record substrate condition, remaining coatings, damp investigations and completed repairs.
- Specify each primer, basecoat, reinforcement, cork layer and finish by current product name. Do not treat historic MASILLA names as confirmed substitutes for DECO 00 FINO.
- Agree thickness, coverage, drying conditions and compatibility with the final skim or decoration using current application instructions.
- Review reveals, floor junctions, adjoining walls and ventilation so that the treatment is considered as part of the room and wall design.
- Keep batch details, installation photographs and the agreed inspection and maintenance record.
The FINO technical sheet distinguishes source-reported values from unverified classification claims. Sprayed-cork fire evidence must not be transferred to FINO or TLICS. Ask for a written TLICS specification review with your survey findings. Tradespeople can use the Academy enquiry route to confirm which practical training covers the proposed system.
Read the assessment and supporting guidance below.
Assess the cause before installation
Cold surfaces can contribute to condensation-related mould, but the assessment must also consider leaks, water ingress, heating, ventilation and other moisture sources. A coating should not be applied as a universal remedy for a wet or defective wall.
Where TLICS™ may fit
TLICS™ is ECOPROCORK’s trowel-applied cork system route. DECO 00 FINO may be considered within a suitable internal build-up, with preparation and a compatible finish agreed for the wall. Its use does not establish permanent mould prevention or compliance for every building.
Use current instructions, not a generic recipe
Confirm the product name, current edition of the instructions, preparation, permitted water addition, equipment, layer thickness, drying and final finish. The earlier article gave a generic water addition and varying thickness/coverage statements. Those are not retained as universal application instructions; follow the current product documents and project specification.
Record the complete specification
Identify substrate condition and compatibility; arrange repairs and appropriate treatment before coating; agree all layers and installed thicknesses; monitor curing conditions; and record installation and handover. Do not treat a wall photograph or a mixing demonstration as a substitute for a method statement.
Explain the expected outcome
A relevant thermal contribution must be assessed for the exact material, thickness and wall. Improvements in surface temperature do not override moisture sources, ventilation or heating. Avoid promises of a warmer room, a fixed sound reduction, an EPC uplift or mould never returning without matching project evidence.
Buying, training and warranty
Use the product guide and Academy to identify the application route. Confirm current approval and written warranty conditions separately. Buying the material or attending a course does not alone establish a suitable installation design.
Use project records responsibly
The retained images illustrate the original application sequence. They are not verified instructions for every substrate, proof of a measured thermal result or a current inspection of the finished building. Share your wall information and investigations with the team before specifying work.
