Chalky Finish Blocker

The Blocker helps you to seal the surface of used and resinous wooden surfaces and serves as a stain remover. It prepares surfaces that are marked with traces of use so that the new paint can then be applied directly. ...And how to proceed? Clean the substrate so that it is clean and free of dust and grease. Then you can apply the Blocker by means of a paintbrush. Let your object dry for 5-7 days, then paint it in the colour of your choice.
