How do you mix a wet dash?
Similarly, how do you mix roughcast?
A standard mix for the roughcast would be 1 part cement to 2-3 part sand mixed with clean water. The stone or aggregate as it is known is then put into the mix. This is usually a 4-5 part aggregate to add to the above mix. Measuring the amounts is known as gauging.
Similarly, how do you use K Rend wet dash? Mix K Rend Roughcast for at least 10 minutes to break down additives, adding 5 - 7 litres of clean water per 25kg sack to obtain a wet plastic mix. While the Dash Receiver coat is still green, throw K Rend Roughcast on to the surface, using a hand scoop or a mechanical applicator.
In this manner, what is the correct mix for rendering?
A common mix ratio used for rendering is 6 parts sand, 1 part cement and 1 part lime. Any general purpose cement can be used, although the sand should be fine and clean of impurities. Coarser sand is usually used as the base layer and slightly finer sand for the top layer.
How is Pebbledash applied?
Pebbledash is a form of render used for the external walls of a building in which the top coat is textured by pebbles and stone fragments to create a rough finish. This is similar to roughcast rendering in which larger stones are applied mixed into the mortar before being applied to walls.
