Plaster sprayers enable you to apply plaster and skim your drywall up to five times faster than traditional methods using a hand float. Most plasterers prefer to use an organic based packaged plaster that is premixed and sold in plastic bags. They prefer this to traditional gypsum based plasters as the plastering machine doesn’t need to be cleaned out after using, if you keep the plaster sufficiently moist. The premixed organic plaster is also better because it can be recycled, virtually eliminating all the waste involved in plastering.
The most common type of plaster pump is called a worm drive pump. This type of pump is driven by a screw that lifts the plaster up to a chamber that’s then filled with compressed air to blast the plaster through a spray nozzle. The screw that lifts the plaster up is driven by a gear that’s powered by a motor, which may be electric, diesel or petrol depending on what kind of plaster sprayer you are using.
Other plastering machines may be driven by a peristaltic pump or even a piston pump. A peristaltic pump is basically just a large tube of plaster that’s squeezed out by rollers. This type of pump also uses compressed air to deliver the final product to the nozzle. The advantage of a peristaltic pump is that it can spray large granules up to 3mm in size. A piston pump sprayer has enough power to spray plaster on 3D panels and stucco without needing to introduce compressed air.
The purpose of a floor screed is to make a level floor surface above a waterproofing membrane that’s structurally sound. This can be accomplished by using a floor screed pump to disperse a large amount of self leveling concrete mix. The concrete mix is runny enough to spread across the floor and fill any holes or gaps that may be there. The consistency of the material allows it to self level, much like a glass of water does when you tip it back and forth. Gravity does all the work which makes leveling a floor a fairly easy process.
A screed is the name of the tool that masons would traditionally use to level large concrete surfaces, which is where screed gets its name. A screed would typically be a long aluminum or wooden beam that masons would drag across the top of their forms to level out the soft concrete below. Nowadays self leveling mixtures take all the work out of leveling a floor.
Floor screed pumps make quick work of laying out the leveling materials, though your new floor can take several weeks to completely dry. Thinner screeds can take less time to dry but require special reinforcing fibers to be mixed in to make them strong. This will also make them more expensive to use, so your trade off is the classic money versus time.
Finding clever ways to make use of site logistics is second only to the quality of work you want to accomplish. The amount of space you have at any given worksite can be quite different from job to job. This can often make choosing the right equipment a difficult decision to make. Finding grout and mortar pumps that will provide the most common sense solution to each of these variables doesn’t have to be a headache.
Mortar machines can deliver fresh grout and mortar up to 200 meters or more from where you mix it to where you apply it. They can even pump up to 100 meters vertically to deliver mortar almost 10 stories up for the biggest jobs. Compared to the traditional method of using hoppers, a mortar machine with a pump can eliminate the need for a crane onsite which can eliminate the risks involved with lifting materials constantly.
Mortar sprayers are designed to deliver mortar directly to the point of application without the need for buckets and trowels. Typically a metal hopper will be filled with mortar or stucco and then fed with compressed air to blast out the mortar. The spray nozzle is similar to a nozzle you would use to spray compressed air. It’s extremely easy to use and the equipment is inexpensive enough to pay for itself after only a few uses. Not only that but it also saves you time, allowing you to complete projects faster, making you more money.
Rendering machines can be used to apply a new coat of mortar or stucco to an existing masonry surface such as cement or brick. A rendering machine can be used to mix the mortar or stucco, pump it to the point of application and also spray the mortar out, all in one. This makes the process of rendering a home or garden wall quick and easy. Pumping the mortar to the point of application takes all the trouble out of site logistics and allows you to get more work done quickly.
You will typically only need to run your machine half the day. After you have sprayed a layer you will then need to spend about the same amount of time finishing the layer with hand tools to make it look just right. You will save so much time and energy using one of these machines that they will practically pay for themselves the first time you use them.
