Making the joint is an essential operation when mounting a Placo® partition for example, but it is extremely delicate and must be done with care. It is therefore preferable to choose a suitable product and follow a precise production process. This step is often seen by aspiring DIY enthusiasts. What is the seal for? And how to apply the plaster to successfully seal it? Here is the answer to your questions.
What is the Placo® seal used for?
The seal slides between the Placo® plates. It contains a special coating which is then reinforced with a strip of microperforated paper. The joint is essential to make the connection between the various Placo® plates which will be affixed against the metal framework formed by the rails. It also allows to hide the fixing screws and the recesses of joint for a more elegant result.
The necessary tools
Before doing your first Placo® joints, it is necessary to equip yourself with the appropriate equipment. You will therefore need a float, a spatula or a trowel, a bucket filled with water, a mixer, joint paper and of course, smoothing plaster. You will also need cardboard cutouts or a tarp to protect your floors from projections. You will have less cleaning to do later. You must also make your joint by adding water to your smoothing plaster. Mix until you get a preparation that is both smooth and pasty. Then let sit before proceeding to the next step. Attention, it is essential to use a special coating for joint otherwise your assembly could not be of the expected quality.
How to make Placo® joints?
A first coat of plaster must be affixed to the Placo® partition before applying a strip of wet seal paper to it and applying a new coat of plaster over the latter. Above all, do not overlap one strip of joint paper with another. Then allow to dry before putting on a new coat of plaster. The first layer should be quite large without, however, the result being too thick. Likewise, a layer of seal must be allowed to dry before applying a new one. Drying times, however, depend on the products used, as well as the conditions within the room. You can easily find the information by reading the instructions on the product. In general, it is preferable not to use a seal at temperatures below 5 ° C. Please note that a Placo® wall to which a seal has been applied is not to be covered with paint or any other finish. It is essential to wait a minimum of 7 days of drying before being able to proceed to this new stage.
