If you have a tin of leftover Hammerite on the shelf or maybe just want a really good way to protect some wood. You may well have wondered if you can use Hammerite on wood. Well fear not, we have done the experimentation and testing for you. Read on to find out can Hammerite be used on wood?
So we have decided to go scientific on this one, lab coats out, safety glasses on, time to get nerdy. We have got four different types of wood, pine, plywood, regular MDF and Green MDF (moisture resistant). We then have two pieces of each type of wood, so eight different pieces of wood in total.
We have then gone ever further and divided these pieces in half with some masking tape. One half will be painted with some red Hammerite and the other half with a red interior and exterior wood gloss. (Leyland trade).
The reason we have two pieces of each type of wood is that we will prime and undercoat one set and paint straight onto the raw wood with the other. So we will have four pieces of wood primed, undercoated then painted half Hammerite and half wood paint. Then we will have another four pieces just painted half Hammerite and half wood paint.
We will be testing how well the paint adheres to the wood, how good the coverage is and also the drying time. But we aren’t finished once the pieces are painted. We then intend to leave the wood pieces outside and compare how well all the finishes last when exposed to the elements. After all, if you are planning on painting wood with Hammerite, you intend for it to last.
So, can you paint Hammerite on wood?
The Hammerite paints straight onto wood really easily. it felt a little thicker than the wood paint, but overall there wasn’t much between the two paints. It seemed to paint onto raw wood and onto undercoat equally well, so no real difference here yet.
The Hammerite covered really well on both the undercoated paint and the raw wood. In fact, I would go as far as to say that it actually covered even better than the specialist wood paint.
One thing to bear in mind is that Hammerite is an oil-based paint, so it will take a while to dry. This, however, also applies to most wood paints as they tend to be oil-based too. Our paints took around 24 hours to be touch dry! The Hammerite and the wood paint seemed to take pretty much the same amount of time to dry.
Before moving our painted pieces outdoor to test their weather durability we decided to test the scratch resistance to see how well the paint has adhered to the wood.
So above and below we have the two pieces of pine wood. The top piece was primed the bottom was not. We scratched the wood with a piece of rough timber. We only ran the rough timber over once, in the middle where the line of green tape is. In both circumstances, you can see that the Hammerite performed better than the wood paint! There is not a mark in the Hammerite but there are scratches in the gloss, particularly on the non primed piece.
Again the same result as the pine, I think t a trend might be appearing here! An interesting thing to note here is how poorly the gloss wood paint adhered to the unprimed green MDF. It scuffed off really easily, I wonder if this is down to the moisture-resistant properties of this type of wood.
Again the Hammerite performed better in our scratch test, although it was much closer here. Both paints have adhered well to both primed and raw plywood. The Hammerite is however providing a much tougher finish time after time.
The Brown MDF performed better than the green but you can still sell adherence issues with the gloss, particularly on the non primed surface,
Well, I think we have already answered the question: can you paint Hammerite on wood? Yes! You definitely can, in fact it seems to where better to both primed and raw wood than specialist wood paint.
For the next stage in the test, we want to test the durability of these paints. So we have moved the pieces outside, into an English winter, keep checking back for progress updates!
