![]() ![]() If this had been done 100% correctly it seems like a lot of this thinset skimcoat work would have been done under the Aquadefense, then Aquadefense, then a layer of thinset to get the tile to adhere. So, I am going to be doing a lot of leveling and feathering out with thinset on top of AquaDefense- which is fine. Also, we didn't have drywall up yet (there was an asbestos discovery so everything went to studs - surprise) so they couldn't thinset the transition between sheetrock and cement backer board. Here's my question, I know they did not shim out the studs and level the walls, and they also put tape on the joints but did not thinset the joints pre-waterproofing. So, cement board is up, they applied AquaDefense and called it good. The plan was they would get the surface ready for us to come in and tile. The contractor put up cement board after repairing some water damage in the old bath/shower wall (window had so much water damage it was literally dirt with an earthworm in it!). Skimming is a step in the process of plastering.So, we bought a house with the intention of doing most of the finishing levels of renovation ourselves and hiring to have structural work done. The reader must keep in mind that the skimming is not a separate coating technique or coating method it’s yet another subset of plastering. Plastering and skimming, are both done in new buildings, but if anyone needs, the walls can be left bare without the plaster. ![]() – The surface colour of the plaster is slight grayish, but in skimming, it is generally white or brown, if preferred. – Surface of the plaster is rough, but the surface of the skim is very smooth and neat – Skimming is also done as an upgrading technique in old buildings, but the plastering is done in new buildings. – Both are applied to decorate, and to increase the durability of the element. – Skimming is a plastering technique, which can be said as a subset of plastering. Similarities and Differences between Skimming and Plastering On top of the skim coating, a paint coat is applied to make the surface more attractive. People use different techniques to level the surface, depending on their level of expertise. The white layer of lime applied on the rough cement plaster is called a skim coat. The thickness of the skimming layer is decided by the requirement of the client, and it can be varied from a thin layer to a thick layer. Skimming is very difficult to do it needs a greater skill to make the surface smooth. Skimming is a thin coat of plastering layer applied to the existing plaster to upgrade the surface. Out of many skim mixtures, the widely used mixture is made up of lime putty and sugar sand. Skim coating is a name for a plastering technique. Cement plaster is usually applied on the masonry walls, where the gypsum or lime plaster is then added again. Cement plaster is made with cement, sand, water and a suitable plaster. Gypsum plaster is made by adding water to Calcium Sulphate (Plaster of Paris). Lime plaster consists of Calcium Hydroxide (Lime) and sand. There are three types of plasters namely, lime plasters, cement plasters and gypsum plasters. Two coat applications are preferred on clay tiles rough masonry and on porous bricks. Greater skill is required to do a better quality plastering. The purposes of plastering are to give a wear resistance to the wall, increase fire resistance of the building elements, and to give a good appearance to the wall. This article is about the features of plastering and skimming, together with the analysis of the differences and similarities. The importance of skimming and plastering has evolved because that they help to bring about a quality product with better appearance. When we talk about the appearance of a building, the plastering and skimming is very important. In a building also, the quality is a major requirement in modern days. The quality of a product is identified through many variables, such as durability, appearance, functions etc. With the modern development, much consideration is given for the quality of a product. ![]()
