ZINGS1L GS1L Gardz Sealer Primer 1 Litre, 1L, Clear | Penetrating sealer and primer for porous, damaged and chalky surfaces. Stabilises substrates before decorating.

Good primer sealer. I use this on fresh new plaster to seal and prime ready for paint. Goes a long way as it’s a thin viscosity so acts as a mist coat. Works well, quality product from established brand. See pics of bare plaster sealed/primed and finally painted white. Recommended.

Great stuff this, was recommended by the by a decorator , it's so good for prepping surfaces.

I’ve used Zinsser Gardz before and it’s an excellent product – does exactly what it should, seals surfaces really well and gives a great base for painting. I had no issues with the product itself and would definitely recommend it. Unfortunately, this particular order was delayed quite a bit, and by the time it eventually arrived I no longer needed it, so I had to return it. A shame, as the product is fantastic, but the delivery experience on this occasion was disappointing.

Used it to seal a plaster wall that had , had wallpaper on it , filled in the cracks and sanded , then washed , once dried painted over with this to seal it in , very thin but easy to apply. Painted over once dried , paint went on top of it well , no complaints

good stuff this

Great product for repair prep applies well and dry's quickly with good adhesion and coverage.

An excellent sealer for multiple surfaces. Very fast drying and paints over brilliantly

Be aware that initially after ordering two tins of Zinsser Gardz (waiting the best part of a week for delivery) I was actually sent by Amazon two tins of 'Zinsser Peel stop' instead which is a different sort of product entirely so this could be an issue for you too and the following review may not apply. After returning however I was sent the correct product by Amazon which can now be reviewed. 'Gardz' is appropriate for sealing any wall that has issues with it's plaster/drywall such as in my case. I did not need to leave it longer than 3 hours to dry and it duly also sealed in all the old wallpaper paste residue that was left over from the previous occupant's lousy attempt at papering. This residue could have caused issues with lining. Now the walls are properly sealed it provides a much better smooth base to apply wallrock fiber liner and then further wallpapering.

This primer is great for stabilizing dry walls that have been stripped of old paint and damaged. It is highly recommended
