Don’t. But If You Insist, Do It Properly.

We don’t suggest you try and plaster you own home because it takes years to master and is a real skill so we suggests getting a professional to do it for you. However, if you insist on doing it yourself and saving the money, here is some advise from us here at the midfield. If you regularly plaster but every time you do, you see the plaster fries it dries out in different colors. How do you achieve a uniform color and where are you going wrong? Well, if it all looks okay when painted then we really wouldn’t really worry. However the difference in color can be due to trowelling at different setting times. For example if you trowel and work one particular area a lot more when it is firming up, then a different color can result. This tends to happen further on in the setting process – so the more the plaster is beginning to firm up and set the more it will change color. There will therefore be less color differences if the plaster is trowelled a bit earlier on if possible and in a methodical way – by trowelling each area to the same degree. Also if firm pressure is not applied – your trowel may not be in contact with all areas, and the color and finish will be different in the areas where the trowel did not make full contact and therefor leaves the patches that you so despise. If the background varies or a thicker coat of plaster is applied in some areas – this can cause different shading. So for a uniform color every aspect needs to be uniform and revised.

If you get streak marks when you are trowelling up it looks like it will be down to lack of pressure. As the trowel is only making contact with the highs. Where it makes contact it changes color so the color shading is showing where the hollows are.

How to rectify it! When the plaster is still pliable it is important to push firmly, and if the trowel is at the correct angle (leading edge approx 10 – 20mm away from surface) the highs will be pushed into the lows. But you do have to push hard. If plaster collects on your trowel then it is scraping it off the highs but not flat enough to push it into the l
ows, so just flatten your trowel into the wall and all should be good. The firmer the plaster is the harder you’ll have to push.
