The gap between the floor and the wall: what to fix so that there are no drafts, dampness, insects

During the repair, various questions and difficulties arise. How to close the large gap that runs between the floor and the wall after removing the old skirting board?

What options and solutions are there to prevent further insect infestations, dampness, and drafts? It is better to do it thoroughly and correctly once than to redo it several times later.

There are many ways to eliminate gaps, but the decision which one to use depends on the specific case. If the gap is about 1-3 cm, then it can be easily repaired with cement mortar, putty or plaster.

Putty is best suited. The solution is applied into the gap and leveled with a spatula.

Polyurethane foam

Before sealing the cracks, the gap between the wall and the floor must be moistened with water. This will improve grip. Shake the foam can, put on your gloves and start applying.

We did just that when renovating the hallway. When the old wooden skirting board was removed, they found a large space clogged with rags. They smelled very unpleasant from old age and were wet.

First, we bought a thin sliced ​​strip in Leroy. It just fit the size (height, width) of the gap. But we miscalculated the quantity and was not enough for one wall. Therefore, I had to foam on one side.

One cylinder was just enough. Top applied putty for polyurethane foam. Then I read that the tree is not recommended for use. It absorbs moisture and the material will swell and rot over time. However, how long does it take for this to happen?

Some people do not recommend foam and plaster for this purpose. These materials absorb moisture and are static.

Acrylic sealant

This material will protect against moisture, will not allow air to pass through, and can change shape when wood is deformed, etc. material. If the gap is more than 4 cm, then the masters recommend that you first close the space with caulking, and use a sealant on top.

Styrofoam, laminate, linoleum, sawdust

Large gaps are easy to seal with foam pieces. Blow out the foam with foam or plaster on top.

Strips can be cut from the finishing material and inserted into the gap. Alternatively, mix PVA with sawdust.
