Ready-Mix Plaster Comparison

Ready-Mix PlasterReady-Mix Spray Plasters are a rapid, cost-effective alternative to traditional (manually mixed & manually applied) plaster for finishing external & internals walls and ceilings. They are formulated for machine application on fast-track & quality building projects. They are supplied as “dry pre-mixed” to the correct consistency for spray application by Plaster Machines.Ready-Mix Spray plastering has been used in Europe, UK, Far-East for many years and is quickly becoming a widespread alternative to traditional plastering due to both it’s economic benefits and rapid speed of application.What are the Major differences between Traditional On-Site Plaster Vs Ready-Mix Plaster vs. Ready-Mix Spray Plaster?Traditional On-Site PlasterReady-Mix Spray PlasterMixing time with water approx. 3-6 seconds before applying.
Retarders slow down the setting time and generally make the mixture more workable.Modern plasters come already mixed with perlite, vermiculite and several other additives.These additives provide a greater degree of insulation and fire resistance.Application by UELZENER ReadyMix Spray Plastering Machine (Mixing-Pumping-ConveyingSpraying) – It has a mixing pump
(rotor-stator). Dry pre-mixed material is fed into the hopper and is transported into the mixing chamber.A constant supply of water, adjustable according to the mixture required, is fed into the chamber to produce a continuous consistent mix.The mixing shaft transforms the dry powder into smooth wet plaster, render, mortar, grout or floor screed in seconds, also drives a pump which conveys the always fresh mixture to the work area.The plaster mixture is very sensitive to variations in water content.The skill of the plasterer is not just in the finishing but in the gauging the wetness of the mixture to be applied.Plasterer adds more water for ease of application.The plaster mixture is sensitive to variations in water content.There are quite a few plasters but two main types: Gypsum-based: They are used indoors only, damp will attack a gypsum based plaster and cause it to crumble. Cement-based: They are used mainly for outdoors, generally for rendering. Cement based plasters can be used indoors for areas that are susceptible to damp and areas that require a greater thickness of cover.Normally Ready-Mix Plasters are available in three finishes: Standard smooth Finish – After spray plastering Base & Finish costs, the plaster is then manually smoothed over with large spatulas or butterfly trowels to give a smooth hard wearing finishFine Textured – After spray plastering Base & Finish costs, the spray may be left to give a “textured” finish. Course Textured – After spray plastering Base & Finish costs, the spray may be troweled to give a “textured” finish. For the texture finishes a hard wearing, water resistant material is used which does not need final decoration; ideal for high traffic areas such as stairwells and corridors.Normally 2 product ranges: Base Plaster: Filler and levelling compound for use over thin joint brick / block systems, uneven in-situ concrete and on refurbishment projects to fill cracks, holes and undulations to prepare surface for final decoration. Normally applied upto 5-10 mm (max. 20 mm) thick in one application. 1 to 2 coats are recommended with 12-24 hrs drying between applications. This is applied using Uelzener Ready-Mix Plaster Machines. Finish Plaster: Normally applied upto 1-2 mm thick as a single top coat on “Base Plaster” or as a 2 coat finish directly onto smooth backgrounds including pre-cast panels, Aircrete panels, composite boards, and/or refurbishment over previously decorated surfaces. This is applied using Uelzener Ready-Mix Plaster Machines.Base Plaster: Normally 1.5–2.0 Kg per m2 at 1 mm thickness Finish Plaster: Normally 1.35-1.5 Kg per m2Ready mix plaster can be applied to almost any substrate including brick work, block work, concrete panels, dry lining, plaster boards, ceramic tiling, artex, wood, glass, steel, old / damaged plaster, and even painted wall coverings (e.g. woodchip).Why should you use Ready-Mix Spray rather than “traditional on-site” plastering? What are the benefits of “Ready-Mix Spray Plaster” using UELZENER German Spray Plastering Machines?Quality…Ready-Mix Spray PlasterIt absorbs and subsequently releases moisture (5-10% of its own weight in water) greatly reducing the incidence of condensation and mould growth.
