Help The Vinyl Floor is Bubbling
2024-09-04
Do you understand flooring bubbles? Bubbles in the floor are one of the most common problems with vinyl flooring. While bubbles can be removed by puncturing or cutting the vinyl to release the air underneath, these fixes can leave visible marks that can make your floor look unsightly.
Since we know how annoying it is to look at a less-than-perfect floor, so we will assist the generals in the first work, and prevent vinyl from developing bubbles. Before we begin, we need to understand the cause of the formation of bubbles:
- Overstretching of the vinyl – in this case, the vinyl sheet will curl and form bubbles as it tries to return to its original shape and size.
- Air pockets are left between the vinyl and the surface beneath it – this can happen with glueless vinyl flooring, especially when a roller is not used to level the surface when the flooring is installed;
- The wrong type of adhesive is used – the adhesive needs to be compatible with the vinyl to have the same expansion and contraction characteristics;
- The screeded area is still damp – residual moisture rises up, accumulating under vinyl flooring and causing bubbles.
How to Avoid Vinyl Bubbling Due to Residual Moisture
The best way to prevent bubbles from forming in vinyl is to allow the mortar to fully dry before installing the final flooring. To ensure that the mortar is dry and ready for the vinyl flooring to be laid, you should:
Perform a Moisture Assessment Test
Because mortar drying times vary with environmental conditions and the types of admixtures and aggregates used, it is nearly impossible to accurately predict drying times. To ensure that the mortar is completely dry, the mortar contractor should perform a moisture assessment before installing the vinyl flooring. Two commonly used tests are the calcium carbide test and Tramex.
The calcium carbide test is the most accurate way to determine the moisture content of mortar. The method involves placing a small sample of mortar in a sealed container along with calcium carbide. The moisture in the sample will react with the calcium carbide to produce acetylene gas, with a pressure gauge measuring the pressure exerted by the gas. Workers can use the readings from the pressure gauge to calculate the exact amount of moisture present in the mortar.
The Tramex meter can be used to instantly determine surface moisture. While this method is more convenient than the calcium carbide test, it is less accurate. If necessary, the calcium carbide test can be used to verify the Tramex meter reading.
Determining the exact moisture content in the mortar is critical because high moisture content affects the quality of the mortar and is the leading cause of mortar failure. In addition, excess moisture may penetrate the surface and affect the final floor.

Plasterers use damp proof membranes
A damp proof membrane laid over the concrete slab is one of the best ways to protect vinyl flooring from moisture. These membranes form an effective barrier that prevents residual moisture from rising and causing a variety of problems, including mold growth, musty odors, buckling of the floorboards, and bubbling of the vinyl surface.
