Best practice depends on the material, the application and how much dirt has accumulated. For a canvas print, water should be enough; otherwise use diluted alcohol or a surface cleaner. We recommend a soft cloth or sponge dipped in a solution of warm water and mild detergent. Test a small area first to check suitability, and avoid stronger chemicals. Cleaning products for babies give good results because they are so mild.
All printed and coated graphics should be cleaned regularly, especially outdoors or on vehicles (avoid aggressive car washes). Dirt will build up over time and penetrate the surface, as it does with film technologies. Avoid abrasive scrubbing, which can compromise the liquid lamination coating and leave the surface porous, allowing dirt to build up more easily afterwards.
Our UV Coating Series can usually meet all the criteria for an ideal liquid laminate for UV ink prints (it’s not just for truck curtains!). However, inks and substrates vary, so compatibility testing is necessary. At Landor, our experience makes this easier, so we recommend you check with us first. Most of our coatings work as a single application. In some cases, though, you may need one of our coatings that can also be used as a digital primer. For example, if you want anti-graffiti protection for UV-printed work, you may need to apply one of our coatings as a pre-coat or digital primer before applying our anti-graffiti coating. We are happy to work and test with you to achieve the most versatile and reliable coating possible.
For HVLP guns, we recommend a pressure of 30 PSI at the gun. The ideal tip size is 1.3 mm, but you can use up to 1.6 mm. If you wish to thin the coating, you can thin it by an absolute maximum of 10%, but we recommend testing first in increments of 2–3% at a time. Note: the more you thin it, the lower the gloss level and the protection compared with our original formulation, which is designed to be as universal as possible and to give the best user experience and protection.
The only size restriction is with a liquid lamination machine. We supply 1.6m and 3.3m liquid laminators as standard, and 5m liquid laminators can be produced to special order. Superwide banners can be hand coated at any size you can lay out on the floor or hang from a wall, as hand application is possible with hand rollers, paint pads, brushes and spray.
We recommend liquid laminating with our canvas liquid laminates before the canvas goes on a stretcher frame. It is always best to leave the canvas to cure for 24h before stretching. Remember, liquid laminating canvas is important because the coating helps prevent future cracking and adds life and archivability.
We are constantly testing and upgrading our coatings for all ink technologies. It is always best to check with us, as inks and substrates may have changed since our latest Latex-certified coating was tested. Our liquid laminates are especially advantageous for vehicle wrapping because of their natural bonding and elasticity, as well as their lower cost compared with cast laminate films, and they work exceptionally well with HP Latex inks. Landor liquid laminates can be used for many other applications with HP Latex inks, assuring adhesion and protection, including digital wallcoverings, outdoor flex-face signs, banners, inflatables, vehicle livery and interior decoration.
Our ClearShield liquid laminates are water-based products that can be shipped in cold temperatures, but they must not freeze. If they arrive during adverse weather, store them in ambient conditions and ideally acclimatise both the liquid and the substrates before use. Allow the coating to cure at temperatures ideally no lower than 15 degrees; the quality and dependability of the coating are much improved in better conditions, such as 18 degrees. Always stir well before first use, and especially well with satin or matt products, as the matting agents need to be thoroughly mixed. Avoid shaking, as this can cause unwanted bubbles and poor results in drier working conditions.
We have a concise library of MSDS (material safety data sheets). Please email us your request and we will reply straight away.
The dried coating will not react at that temperature. We would expect the adhesive to react before the dried film does. Our liquid laminates also work well with most industrial welding equipment.
There are 463 ml in each can. For coverage, allow for coating twice and some loss to the atmosphere. A good estimate is 1–2 m2 per can. We recommend a light first tack coat (6–10″ away from the print), followed by a heavier final coat.
