Undercoat & Primer Paint for DIY Projects

Here’s what to expect from our range of trade-quality undercoat paint and primer. 

Specialist Primers for Every Job

Our selection of paint primers is specially formulated to: 

• Combat mould and fungus: In moisture-prone areas like kitchens and bathrooms, preventing mildew is paramount. Benjamin Moore Fresh Start all-purpose primer is mildew-resistant and is highly forgiving over difficult surfaces. 

• Cover stains: Covering stains from nicotine, water, grease and tannin bleeds, Dulux Trade Uniprimer Aqua White creates strong adhesion and doesn’t require sanding.

• Increase sealing: High sealing power helps to block unwanted odour-causing materials. Smith and Rodger Blockade Primer features a pure shellac base that covers tricky glossy surfaces like tile and varnish. 

• Level uneven surfaces: For unstable and powdery masonry surfaces, use Dulux Trade Weathershield Stabilising Primer. 

Various Finishes

We stock various finishes of interior and exterior primers and undercoats:

• Matt: Perfect for creating a uniform base, matt primers ensure surfaces are non-reflective, better hiding imperfections. Coo-Var Anti-Damp paint builds superior adhesion and is a great primer paint for moisture-prone walls and other interior surfaces. 

• Eggshell: Eggshell undercoats and primers help enhance the adherence of eggshell paints. Bradite One Can acts as an all-in-one primer, stain blocker and eggshell topcoat on wood, walls, metals and plastics. 

• Soft Sheen and satin: Soft sheen and satin products are ideal for highlighting features. Little Greene Intelligent All-Surface Primer is a great low-odour, low-sheen primer that dries in just two hours and pairs well with the designer range of Little Green topcoats.  

Suitable for Multiple Surfaces

We stock a selection of oil and water-based primers and undercoats for multiple surfaces, including wood, plastic, interior walls and exterior masonry.

Interior & Exterior Wood

Doors and skirting boards usually need oil-based paint, so an oil-based primer or undercoat is your best bet for lasting protection. You can also often use oil primers and undercoats on wooden furniture. 

One of our best-performing primers for interior and exterior wood is Crown Trade Fastflow Quick Dry Primer Undercoat. 

Interior & Exterior Walls 

We stock various undercoats and primer paints for walls, drywall and ceilings. 

• Interior primer & undercoat for walls: For walls and ceilings, which are generally finished with water-based emulsions, using the correct undercoat ensures better coverage and durability. Johnstone's Johncryl Water-Based Primer is a great low-odour acrylic undercoat that offers brilliant coverage.

• Exterior primer for walls & masonry: Exterior primer paint often includes additives that support the topcoat in combating UV and weather damage. Benjamin Moore Fresh Start Hiding Primer seals stains and can be used on other materials, including drywall and wood. 

Metal Surfaces

We have various types of metal primer in stock. The two primers we recommend for most metals are: 

• Zinsser Allcoat Exterior Satin: A mould-resistant self-priming paint that can be used on most exterior metals without sanding.

• Coo-Var Red Oxide Metal Primer: An anti-corrosive, general-purpose formula suited for ferrous metal and touch-dry in two hours.
