Farrow & Ball's Wood Floor Primer & Undercoat is for use on interior wooden floors before applying the Modern Eggshell for a durable and longer-lasting finish. It’s important to choose the correct shade of Primer & Undercoat from the four colors. Not suitable for use on exterior decking or other pressure-treated wood.
Using a Primer & Undercoat seals the surface you’re painting on. You should have a full, solid coat of Primer & Undercoat before applying your topcoat, to ensure that your chosen Farrow & Ball finish sticks to it fully, is evenly absorbed, and has a smooth and even finish with a rich depth of color.
Do not paint in temperatures below 10°C or in excessive heat above 30°C.
