Rendering in Minstead

Cleaning down, and knowing when not to. Algae, lichen and black spot come off a sound render with a soft wash and a treatment left to work, never with a pressure lance, which drives water into the coat and takes the face off it. Anything applied is used to its label; the rules on biocidal products are not optional. On a soft or failing coat we say it is past cleaning rather than take your money twice.

Silicone thin coat. Primer, a polymer basecoat with glass fibre mesh bedded into it, then a through-coloured silicone topcoat scraped to an even texture. It sheds water quickly and stays cleaner than most finishes, which is worth real money on a shaded elevation. Beads and stop ends at every opening and a bellcast at the base.

Monocouche. One through-coloured coat laid thick and scraped back the next day. Hard wearing on a plain elevation with a sound background, fussier about weather, and its more granular face holds a little more dirt than a fine silicone finish does under trees.

Sand and cement, pebbledash and Tyrolean. Scratch coat, float coat and then a smooth face, a dry dash thrown on green, or a Tyrolean flicked on. Older dashed walls in Minstead green over readily because the texture holds moisture. Patching means matching aggregate size and colour, and a sample panel goes up first.

Lime render. Solid Minstead walls with no cavity dry out through their own face and want lime, two or three coats, hair gauged in the base. A cement or acrylic coat on one of those traps the moisture and puts the damp inside, which under heavy tree cover happens sooner rather than later.

Tapping, hacking off and cracks. Blown render has parted from its background and sounds hollow. We mark every hollow area on a Minstead wall, because their extent decides between cutting out panels and stripping the wall. Fine crazing is shrinkage; an open crack is movement or a failed bead and needs cutting out and reinforcing.

Render over external wall insulation. Board fixed as a render carrier, then mesh, basecoat and topcoat over it, with Approved Document L setting what a renovated wall is expected to reach. It is warmer and it is thicker, so every reveal changes, and in the National Park how the finished building reads is a design question as well as a technical one.

Rendering in Minstead has no square metre rate. Measuring the wall takes minutes; working out what is already stuck to it is the real survey.

Standing room. In Minstead the house may sit down a gravel track with trees close to the wall, on the village road, or behind the main house as a detached garage. A low gable can be done off a tower. A full elevation needs scaffold, and it stays up until every coat is on. The work at height rules are the reason it appears as its own line.

Hacking off. Putting render onto good brick in Minstead is quick. Removing sand and cement that has blown, or pebbledash that has lost its grip, takes far longer, and Thomas taps every elevation to find out how much of it there is.

Choosing the system. Old solid walls need to breathe, so lime render or another breathable system is normally the choice; a finish full of plastic holds damp in and pushes it inside. Silicone thin coat over insulation, through-coloured monocouche and sand and cement all cost different amounts and perform differently. Where trees shade the wall, a finish containing a biocide that sheds water quickly will stay clean longer.

Edges and fittings. Beads, a bellcast just above the damp course, stop ends round the openings, and removing and refixing sills and pipework all take time.

When a second quote comes in, find out what system and how many coats it covers, whether the old render comes off or is rendered over, and whether scaffold is included.

Algae is not dirt and it does not arrive from anywhere in particular. The spores are everywhere, all the time, and they grow wherever a surface stays damp long enough. A wall in full sun dries within an hour or two of rain stopping and never gives them the chance.

A Minstead wall under oaks, with a hedge or a shrub against it and a canopy dripping on it for hours after the rain has passed, can stay wet most of a winter's day. That is why one elevation is spotless and the one round the corner is dark green, on the same house, with the same render, put on the same day.

Which means that washing it is treating the symptom. The wash is worth doing and it lasts a season or two, but if nothing else changes it comes straight back. The things that actually shift the odds are getting light and air onto the wall by cutting back what overhangs and stands against it, making sure the gutter above is not dribbling down the face, keeping soil and mulch off the base, and, when the coat is next renewed, choosing a smoother water shedding finish rather than a deeply textured one. Do those and a wash lasts years instead of months. Skip them and you are buying the same clean over and over.

Minstead is 15.6 miles up the road from Boscombe. We render houses in the village, Emery Down, Lyndhurst, Cadnam and the lanes across the north of the Forest, broadly SO43, and planning for all of them rests with the New Forest National Park Authority.

Behind the work is Bournemouth Roofing & Building Ltd, company number 15471719, registered in England and Wales. Thomas Hannen, the owner, taps the walls and prices the render in person.

Most repairs in Minstead need no application at all. What decides whether a change to the outside of your house does is who the council is, whether a conservation area or a listing applies, and whether the place sits in a protected landscape.
