I’m using Gunnersens Wall Art Wet Area Panelling…..having some trouble inserting the sheets into the internal corner Joiner moulds…..it’s a very firm fit, easy to put on before the sheet is on the wall…..but inserting once on the wall is difficult….Doesanyone know any tricks or tips to make the insertion easier…..thanks....(Pic is of corner mould type) Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅
