Will Bulls Eye cover lightly waxed woodwork please?
Unfortunately, nothing will stick to wax (other than more wax!) You will need to remove the wax by sanding.
What is the difference between 1-2-3 Bullseye and 1-2-3 Bullseye Plus?
They are both very similar products which act as a stain killer, primer, and sealer. The Zinsser Bullseye 1-2-3 Plus offers a rust resistance guarantee so can be very handy when using over some metals. Ferrous metals generally have a high carbon content, which as a result, make them vulnerable to rust when exposed to the elements. As the Bullseye products are water-based they will be suspectable to this.
Can you varnish on top of Bullseye?
This product is designed to sit underneath paint. It has not been tried and tested with a varnish but as this is also a film forming product, it is likely to work. Try a test area first.
Is the Bullseye product alkali-resistant and can it be used on an internal wall?
Alkali is normally excess mineral salts within the brick or masonry percolating to the surface. if painted like this, it can cause extensive paint failure or salt deposits on the surface. Dry brush the surface using a stiff bristle brush to remove any loose materials and coat using a resistant alkali primer such as Zinsser Bullseye Plus which is alkali resistant to 12.5pH. This is ideal for an internal wall needing resistance.
Can you paint water-based paint over Bullseye 1-2-3 Plus?
Absolutely. The Zinsser Bullseye 1-2-3 Plus is ideal as a basecoat/ primer underneath both solvent and water-based paints for great opacity.
