Ronseal Super Flexible Primer and Undercoat helps prepare bare exterior wood before top coating with Ronseal's 10 Year Exterior Wood Paints. Also ensures the 10 Year guarantee. Use the white undercoat for the light colour range or grey wood primer for all other colours. Can be used on previously painted wood to cover bold colours and dark marks.

Ensure the wood surface to be painted with Ronseal Primer and Undercoat is clean, dry and free from dirt, dust and grease. Put down dust sheets to cover anything that you don't want to get paint on.

Bare Wood

  1. Lightly sand wood with a 120 grit sandpaper, sanding in the direction of the woodgrain
  2. Remove any wood dust, and wipe the wood surface with white spirit
  3. Fill any gaps or splits in the wood with a suitable wood filler, removing any excess

Previously Painted Wood

  1. If your old paint is in good condition, just give it a light sand to help the Primer and Undercoat stick
  2. If it's flaking or cracked it must be sanded back to bare wood
  3. Use 120 grit sandpaper and sand in the direction of the woodgrain
  4. Remove any wood dust, and wipe the wood surface with white spirit
  5. Fill any gaps or splits in the wood with a suitable wood filler, removing any excess

Always do a small test area before starting any project and follow the manufacturer's instructions on the tin at all times. Stir contents of tin thoroughly before and during application.

  1. Apply two coats of Ronseal Primer evenly using a good quality synthetic brush, finishing in the direction of the grain
  2. When using more than one tin, intermix before use to ensure an even colour
  3. Apply a second coat after four hours
  4. After the second coat, give it a light sand with a 240 grit sandpaper

You can NOT go wrong with this primer and undercoat This product DOES what it says on the tin by Siobhan Cosgrove

Ronseal Super Flexible Primer and Undercoat can be got in White or Dark Grey. I got the Dark Grey because the gloss i was putting on was Burgundy. What I love about this product is you get two in one. The primer mixed in with the undercoat, So no need to buy a primer and an undercoat.

Easy to apply, good coverage, dries quickly, small amount goes a long way by Zuzana Krejcarova

Seems like a good product, only used it recently on decorative timber at the front of the house. Will have to wait for a few years to see if true to the claims on the tin.

The paint dried extremely quickly even though the air temperature was around 18 degrees this made painting the intrecate areas of the windows difficult by Richard Hales

This gave primer and undercoat good coverage as a base for the top coat

Early days but so far so good by Ros Joy

Although a bit drippy went on easily and well. Recommended for use before the Ronseal top coat which is meant to last for years and years. Time will tell but hope so.

As expected by William Stretton

As with Ronseal products...it does what it says on the tin.Follow all the prep instructions,including drying times and you won't go far wrong. Take shortcuts...and you will. Patience is a virtue.

The right primer is essential by Mike

Gives a good finish but benefits from light sand after first coat. Easy to clean brushes in water and soap. Great price and excellent delivery.
