The best paint for interior walls, so far in my experience pound for pound, is Colourtrend paints.
Not only is it Irish, but it is also superb in its application, especially if you use good quality brushes and roller sleeves. The finish on a well-prepared wall is second to none.
It may take more time or cost you more money, but if you get a decorator that knows what they are doing then the finish speaks for itself, and it is worth the added expense. Colourtrend ceramic paint is better again if you have kids, as it is washable and goes on like a dream.
But above all, the reason it is the best paint (for money) is that unlike Farrow and Ball, which is arguably better again, Colourtrend comes in 10 litres. This effectively means you are getting a most excellent paint at half the price of its leading competitor.
In addition, you can get it mixed into any colour, including Farrow & Ball. It may not have that soft look of a Farrow & Ball tint but in this painters opinion, it’s Irish, it’s the best paint, is the best value for money and comes in great colours.
At the risk of being repetitive, I would have to say that after using every paint on the market, Colourtrend would again be the best value for money. Being an extremely good paint to work with and to finish, especially when the surface has been prepared properly, and been undercoated sufficiently with Colourtrend undercoat. It has very low odour and, as mentioned before, it’s Irish. Paint and decorate in Dublin with Colourtrend.
