Protect your paint from leaking sap.

If you've ever painted bare wood without using a knotting sealer, you may have seen a yellow stain appearing on your beautiful paintwork weeks, months or even years later - just above where the knots are. This is because knots continue to leak sap as time passes, and they will discolour your paintwork.

By applying Shellac Knotting Primer to the knots on your wood before painting, you'll seal them and prevent their sap from leaking.

Available in 125ml (4.2 fl.oz.) and 1L (33.8 fl.oz.) sizes.

This product is only available for UK customers and cannot be shipped to the US

    Hello Michiel, do you read these things? Probably won't use anything from the order till Spring. However everything was beautifully packed.Nevertheless I have found that shellac is the only thing that works well on knots. Happy Christmas. T andT
