Storing and Handling Liquid Laminates

A liquid laminate can only perform as well as the condition it is in when it reaches the print. Frost, dust and poor mixing spoil more coating than people expect. This guide covers how to receive, store and prepare liquid laminates, and how to handle freshly coated work so the finish survives until it is installed.

Receiving a delivery

Landor ships from its UK and French distribution centres, usually reaching customers across Europe within two to three working days. When coatings arrive, check containers for damage and leaks, and move them indoors promptly, particularly in winter.

Water-based laminates such as ClearShield can be shipped in cold weather, but they must not freeze. If a delivery arrives in adverse weather, Landor advises storing it in ambient conditions and, ideally, letting both the liquid and the substrates acclimatise before use. If you suspect a container has frozen, contact Landor before using it.

Where and how to store coatings

Choose a storage area that stays frost-free all year and is not exposed to strong heat. Beyond that, general good practice applies:

  • keep lids firmly closed when not in use to keep out dust and stop the coating skinning;
  • store containers upright and off cold floors;
  • keep solvent tins and aerosols separate from water-based products, away from heat sources, and in line with their safety data sheets;
  • label any decanted coating clearly with the product and finish;
  • use older stock first.

Shelf life varies by product. Check the label or product data sheet, and ask Landor if you are unsure whether older stock is still usable. Safety data sheets, which Landor supplies on request, are another place to check storage requirements.

Choosing the right pack size

Buying the right quantity reduces the time coating sits part-used. ClearShield is available in 1 litre, 5 litre and 20 litre containers. For small or occasional jobs, the Landor starter kit includes 100ml of the liquid laminate of your choice with a roller tray and a high-density foam roller or foam brush, which is useful for testing media before committing to a larger pack. ClearJet aerosols contain 463ml per can.

Preparing the coating for use

How you open and mix a container matters as much as how you store it:

  • Stir, do not shake. Landor recommends stirring well before first use. Shaking can create bubbles that end up in the finish, especially in drier conditions.
  • Take extra care with satin and matt. The matting agents need to be thoroughly mixed, or the sheen will be uneven.
  • Pour off what you need. Decanting into a clean tray, rather than dipping into the main container, helps keep the stock free of dust and fibres.
  • Bring it up to temperature. For ClearShield, Landor advises curing at no lower than about 15°C, with better results at around 18°C, so cold coating and cold media are worth avoiding.

On Landor’s roll-to-roll coaters, an automatic supply and return system with filters keeps machine coating clean and recirculates it with very little waste.

Handling coated prints

The most vulnerable point is between coating and installation. Dry to the touch is not the same as cured, and freshly coated surfaces mark easily.

  • Keep coated work in a clean area away from dust, moisture and direct heat while it cures.
  • Store pieces flat, or upright with space between them, until the stated cure is reached.
  • Do not stack, roll tightly or wrap work early. This can cause blocking, where coated surfaces stick together, or imprint texture from packing.
  • Only place interleaving against the face once it has fully cured.
  • Handle work by unprinted edges, or by stretcher bars for canvas, with clean hands or gloves.

Packing for transport

Once fully cured, pack coated work so the image face cannot rub against cardboard, bubble wrap or another print in transit. Use clean packing materials and avoid putting coated faces against each other. For export or multi-site work, consider the whole journey, from storage rack and courier to the installation team. Good packing protects the time and coating you have already invested.

FAQs

Questions we’re often asked

Water-based laminates must not freeze. Store them in frost-free conditions and contact Landor before using any container you think has frozen.

No. Stir it well instead. Shaking introduces bubbles. Satin and matt grades need particularly thorough stirring to mix the matting agents.

It depends on the product. Check the label or data sheet, or ask Landor.

Only once the coating has reached full cure, not simply when it feels dry. Stacking too early can cause blocking and marking.
