 HB42 PS1 Primer-Sealer Stain Block

Combining performance, cost effective and excellent availability:


Leading sealants and adhesives specialist HB42 has launched a premium white shellac primer-sealer, PS1 Primer-Sealer Stain Block. Formulated for high performance, permanent stain blocking, this powerful product blocks stains in just one coat. 

Now available at TopDec Decorating Supplies, PS1 is suitable for interior surfaces and to ‘spot’ exterior surfaces. Providing a rapid matt finish that covers stains in one coat, it is ideal for use on all interior woodwork, plaster, glossy and hard to paint surfaces such as tiles, varnish, or gloss paints.  

The special formula blocks odours including mould, smoke and nicotine and seals-in stains from grease, water, smoke, wood knotting and sap residue, crayon, ink, lipstick, rust and more. The product can also be used to seal porous surfaces so top coat paints have better coverage. 


Another advantage of PS1 is that it dries in 15 minutes and is ready for a recoat in 45 minutes. The primer sealer is white, can paint any surface and no sanding is required before you coat it with any paint.  It is also tintable with universal tinters. 

“PS1 combines professional performance backed with our commitment to cost effectiveness and availability for the trade,” explains Scarlet McAleese-Banks, HB42’s Joint Managing Director.  

“With over 150 years of experience, Hilton Banks is committed to expanding the HB42 range with high quality products that meet the high demands of trade users and the launch of PS1 is part of that ethos too.” 

To get a feel of just how good the PS1 Primer-Sealer Stain Block really is, HB42 asked an independent decorator to try it out and share his views. You can read Mike Gregory’s full review here.

HB42 PS1 Primer-Sealer Stain Block is available in 500ml, 1ltr, 2.5ltr and 5ltr tins. For more details visit
