4 THE BRICK FACADE Protection Systems for One of the Oldest Building Materials Brick is one of mankind s oldest and most popular building materials. The reason then as well as now is because brick is attractive and it has a long service life that not even concrete can achieve. But brick facades are not only made of bricks, they also have joints between the bricks. These joints are usually not as durable as the brick and often become the weak point of the facade. Large quantities of moisture absorbed by both or just one of these two building materials is the starting point for damage. Effective protection against moisture is needed here that equalises the differing absorbency of brick and joint mortar and reduces the facade s water absorption overall. This can be achieved, for example, by treating the facade with hydrophobizing impregnation agents. The protection system developed by Remmers for fair-faced brick masonry work provides permanent protection against moisture penetration, guaranteeing the longest possible service life. 4

5 1 2 3 Cleaning & de-salting Cleaning not only improves the appearance. Crusts of dirt store moisture and contaminating substances and prevent the substrate from drying. Salts near the surface are removed with Remmers Desalting Compress. The compress is applied like a render and then removed after approx. 3 weeks together with the salts that have migrated into the compress. Removal of joint mortar The renewal of damaged joints is a part of restoring practically every fair-faced stone facade. With the exception of the grout jointing procedure, joints must be chased out 2 cm deep or double the width of the joint. Stone replacement & pointing Damaged bricks are replaced or restored with Remmers Restoration Mortar SK. New pointing is then carried out with a joint mortar that has the desired binder, size of grain and colour. 4 5 Hydrophobizing & graffiti protection For preventative, long-term protection against moss, fungi and algae, a liquid green growth inhibitor can be applied before hydrophobizing treatment is carried out. Hydrophobizing, which can be carried out with either a liquid or a cream product, is always applied as the last step. Semi-permanent Remmers Graffiti Protector facilitates the removal of graffiti. Coating or scumble As an alternative to hydrophobizing treatment, the facade can also be rendered water repelling with a silicone resin coating which is quite typical for some regions or with a less visible silicone resin scumble. Pointing for porous brick Along with the classic method of pointing by hand, joint mortar can also be applied by machine which is quite practical, particularly on large facades which usually have wider joints. Remmers Joint Mortar MG was especially developed for this purpose and is available in two formulations: capillary active or hydrophobic. 5

6 BRICK GROUT JOINTING Perfect Appearance, Joints and Facades Permanently Rain Tight Funcosil Brick Grout Jointing essentially consists of two elements: renewal of joints by applying a hydraulic setting joint material and subsequent water repelling treatment of the facade with hydrophobizing agents. The joint material is a fine-grain grout with sulphate resistant binders. This ensures good resistance, also in masonry work contaminated with sulphates or gypsum which is often the case with old buildings. The grouted joint is distinguished by especially strong adhesion to the sides of the joint which is a result of the quality of the mortar and the application technique. The procedure (brick grout jointing) is very economical since it has a lot of advantages as far as time is concerned. Since the joints do not have to be chased or cut out which often damages the edges of the brick in the process, a lot of time is saved. Applying the mortar to the joints is also much easier compared to a conventional jointing tool. Another significant advantage: even narrow joints and small cracks (too narrow for a jointing tool) are filled flush with mortar. With all of the time that is saved, you can assume around 25% time and cost savings. Funcosil Brick Grout Jointing has unique advantages: Renewal of joints and water repelling treatment of the entire facade The joint grout adheres strongly to the sides of the joint Joints and brick have a uniform water absorption coefficient Saves time and money compared to pointing by hand The dry facade improves thermal insulation Brick that has been made water repelling, hydrophobized zone Frictionally bonded, repaired joint, made water repelling Joint and brick flush with the surface (no cracks, edges or surfaces that could be attacked) Preliminary impregnation in a flow coating procedure Coarse cleaning and compaction of mortar Final cleaning in the initial state of setting Application of the grout mortar Second cleaning with a slit foam rubber float Re-impregnation with Funcosil SNL 6

7 FUNCOSIL HYDROPHOBIZING AGENTS Permanently Safe against Moisture Water is the beginning of the end of everything A good many of the mechanisms that cause damage to buildings are directly or indirectly associated with the absorption of moisture by the building material. For example, the amount of pollutants also increases with the penetration of moisture into a building material. Salts, for example, are transported into the building material in dissolved form; pollutants in the air are taken up by rain (acid rain) which in turn is transported into the facade. Physical properties of the building, e.g. thermal conductivity, change with the content of moisture. Since water has good thermal conductivity, reducing the moisture content of a building material means increasing its heat insulating properties. Water repelling treatment of a single skin brick facade, for example, can lead to a shift of the dew point which reduces the risk of mould infestation inside of the building. Little attention is paid to the effect on many building materials to lose strength when the moisture content is increased. The damage processes in conjunction with water are much more complex than the few problems discussed here. But for many of the damage mechanisms named here, water repelling treatment is the only answer. Hydrophobizing treatment with one of the Funcosil products will protect your bricks from damage and save costly energy. Funcosil FC Ready to use right out of the bucket onto the wall Easy to work, also over-head Little material required per m 2 No loss of material since it does not run No time consuming extra protection High active ingredient content provides a long-term effect Sets a new standard for economical impregnation of facade surfaces Liquid with Funcosil SNL Excellent penetration capacity on more porous substrates Outstanding long-term stability Proven in practice for decades Because of its cream consistency, work can be executed right up to adjoining areas, e.g. window sill High water repelling effect 7
