Before you start
One of the big advantages of the Marabu liquid laminate range is that it can be applied by hand or roller; a coating machine is only needed for heavy use. Good results come down to preparation, a clean environment and an even, unhurried technique.
Important: This page gives general good practice only. Coating method, dilution, number of coats, drying times and safety information vary by product. Always follow the liquid lamination handbook and the instructions for the specific laminate you are using.
Choose the right laminate
Match the laminate to your ink and application. ClearShield offers UV-inhibited, non-yellowing, exterior-durable options, including Type C for canvas, VG for vehicle graphics and 20° Satin LL for wallpaper. ClearJet is formulated for water-based and water-sensitive inks. If you are unsure, read film vs liquid laminate or call us.
Step by step
- Let the print dry fully. Ink must be completely dry before coating. Freshly printed media can still be giving off solvents or moisture.
- Prepare a clean workspace. Work in a well-ventilated, dust-free area at a comfortable room temperature. Cover the bench and anything nearby.
- Test first. Coat an offcut printed with the same ink and media. Check adhesion, finish and that the inks do not bleed or lift.
- Prepare the laminate. Stir gently rather than shaking, to avoid introducing air bubbles. Decant into a clean tray.
- Load the roller or brush evenly. Use a clean, lint-free roller or brush suited to the product. Remove excess so it does not drip.
- Apply in long, even strokes. Work in one direction across the print, slightly overlapping each pass, and keep a wet edge so strokes blend together.
- Do not overwork. Once an area is coated, leave it. Going back over partly dry laminate can leave marks.
- Check under raking light. Look across the surface at a low angle to spot missed areas or bubbles while the coat is still wet.
- Leave to dry undisturbed. Keep dust away and allow the full drying time before handling, applying a further coat, stretching canvas or installing.
- Clean tools straight away. Follow the cleaning advice for your product.
Common problems and fixes
| Problem | Likely cause | Prevention |
|---|---|---|
| Bubbles | Shaking the laminate, rolling too fast | Stir gently; use slow, steady strokes |
| Streaks or roller marks | Uneven loading, overworking | Load evenly; keep a wet edge; leave to level |
| Dust in the finish | Dusty room or tools | Clean workspace; cover while drying |
| Ink bleeding | Ink not dry, or laminate not suited to ink | Dry fully; test; choose ClearJet for water-sensitive inks |
Tip: Several thin, even coats are usually better than one heavy one, but check the handbook for the recommended approach for your product.
