You can do something else which is simpler and will let you cover the wall as pennies permit and growth requires.
Buy some strong wire and a set of vine eyes from a good DIY store. These are screw fixings with a stem and round eyes on the end through which you pass and stretch wires to which you loosely attach your climber. You can buy tensioners which will stretch the wire taught or you can just pull it tight using a pair of pliers and then twist it to secure it. Maybe add proper tensioners later.
You need to set the wires horizontally on the wall and space them at 12" to 18" or 30 to 45cms apart going upwards. You can then train the stems of a rose, clematis, honeysuckle or maybe a grape vine or blackberry depending on aspect and soil type.
When you plant your climber, make its planting hole away from the base of the wall so its roots are not in a rain shadow and make sure you work in plenty of good quality garden compost or well rotted manure to improve the soil in and around the planting hole. Keep your plant watered during its first year until the autumn rains arrive.
