Sticking with the specialists… and a little bit of acrylic primer

You’ve just had a call from an un-happy customer. Three months ago, you were commissioned to re-tile their newly fitted bathroom suite. Looking back, you prepared the area, primed it, put down your grout and adhesive and did a great job on the tiles – the customer was thrilled with the job. So why, a few months later, has all your hard work gone down the toilet and all your tiles, adhesives in tow, fallen off?

  • Not commonly know amongst all tradesmen, there is a huge difference between using a PVA primer opposed to an acrylic primer
  • You’ll all remember PVA glue from primary school. The stuff that, to the teachers’ dismay, ends up all over your hands, but with a touch of soap and warm water it’s soon gone. Fundamentally, that’s what PVA primer is
  • Jane Deegan, Assistant Brand Manager of Dunlop Adhesives discusses the implications of using a PVA primer as opposed to an acrylic primer to encourage jobbing builders not to get themselves into a sticky situation
  • When a substrate surface is treated with PVA, it partly soaks in to the body of the substrate and partly sits on the surface in a similar fashion to wallpaper paste
  • When the tile adhesive is applied to the wall, the water in the adhesive causes the PVA to become “live” which prevents the adhesive from penetrating the substrate resulting in a poor mechanical grip
  • An acrylic primer soaks right into the substrate and stops the sponge like “draw “effect
  • Tradesman should know, when using a cement-based adhesive, it should not be applied directly to the plaster substrate as it causes a chemical reaction, a problem known as “Ettringite failure”
  • Using an acrylic based primer will prevent this chemical reaction from happening
