On-Site & Ready-Mix Plaster Comparison Essay
They are formulated for machine application on fast-track & quality building projects. They are supplied as “dry pre-mixed” to the correct consistency for pray application by Plaster Machines. Ready-Mix Spray plastering has been used in Europe, I-J, 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 Plaster Highly labor intensive task Ingredients / raw materials are measured and mixed in small quantities on site Ready-Mix Plaster Labor intensive task Ready-Mix Spray Plaster Not at all labor intensive Dry complete Ready-Mix in bags – Absolutely no mixing of ingredients required at site Mixing time with water approve. 6-10 minutes before applying Mixture not workable Dry Ready-Mix in bags – normally no additional mixing of ingredients at site approve. -10 umlauts Mixture less workable Normally no admixtures Only some admixtures Application by hand – Mix is picked up by the tradesman and laid onto the wall prior to floating and trolling Application by hand – Mix is picked up by the tradesman and laid onto the wall prior to floating and trolling Mixing time with water approve. 3-6 seconds before applying Retards slow down the setting time and generally make the mixture more workable Modern plasters come already mixed with permit, vermiculite and several other additives.
These additives provide a greater degree of insulation and fire resistance Application by LUCERNE Readmit Spray Plastering Machine (Mixing-pumping-conversationally) – 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 mutinous 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.
I nee plaster muleteer 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 Setting Time approve. 10 to 20 minutes Very Low Productivity Inconsistent Quality Not at all flexible – Results in high cracking, flaking, hipping The plaster mixture is 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 Setting Time approve. 0 to 15 minutes Low Productivity Not flexible – Results in cracking, flaking, The mix is sprayed with remote controlled spray gun Fixed and accurate quantity of water is dosed in the dry ready-mix. Hence the wetness of plaster is independent on the plasterer Setting Time approve. 8- 15 minutes Very High Productivity & Efficiency Consistent High Quality Inherent Delightedly – Much less prone o cracking, chipping and flaking How many Types of Ready-Mix Spray Plasters are available? 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. What Finishes are available in Ready-Mix Spray Plaster? 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 finish Fine 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 trowels 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. What are the Ready-Mix Spray Plaster range? Normally 2 product ranges: Base Plaster: Filler and leveling 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 Upton 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 Lucerne Ready-Mix Plaster Machines. Finish Plaster: Normally applied Upton 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 anneals, Aircrew panels, composite boards, and/or refurbishment over previously decorated surfaces. This is applied using Lucerne Ready-Mix Plaster Machines. What is the Coverage of Ready-Mix Spray Plaster?
What are the Advantages to the Contractor? For the contractor the key benefit is also that of higher consistent quality, resulting in lesser correction, no hacking off and so reducing the likelihood of rectification costs. Costs are further reduced as construction can proceed more quickly and importantly there is less risk of damage to materials on site. Other advantages to the contractor include early removal of scaffolding, less waste on site and low maintenance cost. But he key benefit is that using a machine enables an accurate account of the material used.
