Re the lining paper, difficult to see from the pics on phone but you could rub over by hand with 200 grit which flattens the top off the texture, spot fill any holes with fine surface filler and then any areas with obvious roller marks fill with a very thin layer using a wide blade at 90° to wall so you are just filling the tiny dips in the surface and then a very light sand over the top.
Use a heavy pile roller which will add texture.
Any big areas of flat filler I’m using a damp sponge and some fine filler to add some texture to match the surrounding surface.
Its what I’m doing on the problem areas, have stripped one wall due to blown plaster but don’t have the time or budget to do every wall.
I have the titan one from Toolstation. Very likely similar. Mine died within a year after being thoroughly abused but was replaced with no questions. Screwfix seem to be similarly good on returns so long as you have your receipt/online order in your account.
@Howard @hugo7 thanks will order one today.
