Plaster Finish for Internal Walls

There are different types of plaster finishes that have been used for internal walls over the years. Some of those types include lath and plaster for wooden framework, plasterboard on wood framework, plaster on masonry walls, and dry lining plasterboard for masonry walls.

Repairs to an interior plaster wall should be applied using the same techniques and materials as the original plaster finish on the wall. Traditional lime putty plaster used in older construction is a lot softer than the modern gypsum plasters and it is not recommended that the two be mixed.

An advantage to using lime putty for the coating in the past, was that it was extremely flexible and able to cope with movement of wooden framework on a home. The downfall, however, was that a single layer of the lime putty could take several weeks to dry before another layer could be applied. For this reason, cement or gypsum were then added to the mixture.

When remodeling an older home, it is often found that there are plastered walls. If the homeowner does not want to remove the wall plaster to replace it with drywall, the walls can be re-plastered. The practice of re-plastering the walls takes practice. Some of the steps include wall preparation (installing metal lath on the walls, attaching the lath, hanging lath pieces, staggering joints, and installing metal corner bead strips over the lath) and installing the plaster by mixing the plaster through to applying the plaster onto the trowel and spreading the plaster on the metal lath. Because of the detail required in applying plaster finish to interior walls, hiring professionals to successfully complete a plastering project in your home is highly recommended for best results.
