Linseed Paint is very easy to use. It has been around for centuries, is free of nasty chemicals (including VOC's) and is incredibly durable if used correctly. It can be easily applied to pretty much any surface or substrate, but is most commonly applied to wood and metal.
Let's start with applying Linseed Paint to bare timber. This is the ideal surface to paint on, as the oil in the paint penetrates the wood, which provides excellent weather protection.
Firstly, make sure your timber is clean and free of dust, and you're ready to apply your first coat of Linseed Paint.
How do I apply Linseed Paint ?
Linseed Paint has an eggshell finish, similar to a satin matt finish. On windows and doors, we recommend a total of 3 coats, for finish and durability, however in other applications such as fences or furniture, fewer applications will achieve great results.
The first coat should be a primer coat, of Linseed Paint, Raw Linseed Oil and Balsam Turpentine, to the ratio of 50/35/15. Use a clean tin to mix your primer coat, and we find that using a measuring stick with ratios pre-marked on it makes the job a bit easier.
This primer coat will take approximately 1 day to dry, depending on weather conditions, and can usually be over-painted the following day.
Subsequent coats should be pure Linseed Paint, straight from the tin. These will take 1-2 days to dry, again depending on weather conditions.
What materials can I paint onto?
As we mentioned earlier, Linseed Paint can be applied to many surfaces, but the effectiveness and finish of your efforts will only ultimately be as good as the quality of the surface you're painting onto.
Putting effort into the preparation of the surface will be time well spent, and whilst a coat or two of Linseed Paint on top of old, cracked, chemical paint may look good initially, it will still be subject to the failure of the existing old coats over time.
Wood should be stripped back to its raw state, concrete should be as clean as you can get it, and metal should be sanded off any old paint or rust.
The application differs slightly for metals, where you need to apply 2 coats of Iron Oxide Primer, followed by 2 coats of paint, straight from the tin.
How can I remove old paint quickly and easily?
Paint should be removed mechanically (with a bit of elbow grease) and certainly not chemically. If you're undertaking larger projects, we would recommend using the Speedheater Cobra - an ingenious and time-saving tool that uses infra red heat, which gets rid of the old paint effortlessly without damaging the material you're painting on.
How do I keep my finish looking great?
Linseed Paint is incredibly durable. Over time (typically 10-15 years), UV light will break down the oil on the surface, which will result in a more matt, chalky finish. This doesn't mean that the paint is failing or cracking, like standard petrochemical paints, but just needs an occasional wipe of Raw Linseed Oil to bring back that initial, just painted, look and feel.
