The cost vs. benefit of removing all the existing plaster is more usually the overriding factor. Normally, the plaster would only be removed around fixtures and fittings and, if the waterline tile is not being replaced, a band about 3-4 inches below the tile is removed. This allows the new plaster to transition to these areas without being troweled too thin. The existing plaster should be examined for hollow spots and any delaminated areas removed as well. In preparing the rest of the existing finish for recoating there are several alternatives. In each, the goal is to provide a rough surface for the new plaster to adhere to. Acid etching the plaster with muriatic acid will roughen the finish and using an acrylic boning agent in the new plaster is a common practice. Acid etching however presents the problem of disposing of the used acid. Sand blasting is another means, though it can be as expensive as the replastering itself. A growing trend is to pressure wash the existing plaster and apply a scratchcoat or precoat. Scratchcoat is a modified masonary product that bonds tenaciously with the existing finish and provides a rough finish for the new plaster.

Is a lath and plaster wall ever load bearing?

Lath and plaster is just an old type of wall finish. Like drywall is a wall finish. What the wall is constructed of underneath the lath and plaster and where it is placed in the building determine if it is load bearing or not. A lath and plaster wall could be load bearing or it might not be. IF it is an outside wall, it most certainly is load bearing. other than that, the best way to figure it out is to have a structural engineer tell you wether it is or not. Even if it is load bearing it may be possible to remove it if a beam is put up in place of the wall. Really, the best and safest way to decide is to have a engineer look at it.

Why is plaster of Paris named plaster of Paris?

Large deposits of gypsum were to be found just north of Paris. These were used to produce the fine white decorative plasterwork of the best houses in France. Interest was generated abroad in this new material and it became a general term for gypsum plaster. Prestia Lafage still mine and produce Plaster of Paris at Meriel just north of Paris. Whilst in the UK the best deposits are to be found at Newark in Nottinghamshire, currently mined by Saint Gobain Formula (formerly British Gypsum) New technology has made it possible to produce Plaster of Paris by using an Autoclave instead of in open pans. The plaster produced in this way forms longer crystals resulting in a substantially harder and denser material known as an alpha plaster. This is blended with the normal (beta) plasters to produce many different products of varying strength and porosity. But these many products are all still Plaster of Paris

Can you use muriatic acid to clean your spa?

Muriatic acid is very dangerous. It can cause lung damage even death. Please read instructions. Yes it can be used to clean the plaster only. It will not remove any hard water (calcium ) deposits on the tile. In fact it's best not to let it linger on the tile and grout because it will etch the tile and remove the grout. Oh it will also remove the plaster if left on too long. It's better to hire a professional. I clean tile for a living but refuse to acid wash pool/spa d/t danger.
