Rear extension rendering - Chigwell

The rear extension in Chigwell was rendered over the new blockwork, above a brick plinth. A scratch coat went on first and was combed with a wavy key so the next coat could grip, taken along the side wall and around the garden front.

The white uPVC windows and doors were already fitted and kept in protective film while the walls were rendered. Pipe sleeves were built through the side wall, and the coat was worked up to the white fascia and gutter.

The final coat of render was mixed with lime: 1 part cement, 1 part lime and 6 parts sand. Plasticiser and waterproof liquid were added to the mortar.

The scratch coat was then floated and sponged to a tighter face. The garden elevation is finished in a pale render, with French doors and a side door opening onto the garden. The earlier photos show a bay window base built up the same way, from the first scratch coat to a ruled, sponged finish.
