Monocouche Renders weber.pral monocouche renders create an external, decorative, through-coloured finish suitable for most types of brick or blockwork. The factory production process for weber.pral renders ensures quality materials are used in a controlled and accurate method, using proven engineered formulations which result in high performance in practice. Colour and Texture - A wide range of colours and textures are possible creating a wide range of options for the designer. Colour charts are shown on the following pages. Fast Track Construction - The use of advanced technology enables the weber.pral range to be applied in one application. In addition weber.pral M can be applied by machine creating even faster application. Low Maintenance weber.pral renders are through coloured in nature and therefore do not require further decoration. Should the need arise the render can be easily cleaned with a “hobby� style pressure washer and suitable detergent. Stonework design such as ashlar can be replicated by cutting recessed joints into the finished render using specialist tools. Changes in colour or thickness can be employed to produce raised features such bands, plinths and stones. Alternatively the render can be finished as a traditional roughcast spray finish which is particularly effective in areas of high exposure.

Good Site Practice The substrate should be constructed of durable and moderately strong materials specifically designed to receive modern renders.
An application of weber.rend aid will deter sulphates from crystallising and impairing the bond of the render.
They should be clean, suitably dry, sound and free from anything that may interfere with the adhesion, such as oil, grease, organic matters and soluble salts.
Suction control
Strength
Suction
Key
The substrate should be designed and constructed so that it adequately supports and restrains the rendering.
Good adhesion of a cement render is greatly reliant on the suction in the substrate. Excessive suction will impair the hydration of the rendering and therefore affect its bond with the substrate. On the other extreme, low suction substrates will not offer sufficient capillary action to gain a good bond.
For the background to give support it must provide an open or preformed textured surface to allow the render material to penetrate and promote aggregate interlock between the render and the substrate.
The substrate, including any joints in masonry, should be no weaker than the rendering material used.
Suction control, particularly when using lower density block, should be achieved by spraying the wall with an even mist of clean water prior to rendering. If there are a combination of issues, such as varying suction or insufficient key in addition to high suction, then an application of weber.rend aid is recommended. Please note that mist spraying with water should be done in a controlled manner in order to avoid saturating the blockwork. Excessive watering will increase drying shrinkage and can induce cracking in the block. Any such cracking is likely to be reflected in applied materials.
Section through substrate with suitable key and suction Zone of key formed through suction
Zone of mechanical key
Blockwork Generally a block is manufactured with an open texture or a designed key for rendering. Relying on the raking of mortar joints is not sufficient to provide the key alone. Smooth dense blocks with little mechanical key should have the key enhanced by an application of weber.rend aid stipple coat. The strength and density of the blockwork should be assessed in regard to its compatibility with the proportion of cement content of the chosen rendering. Low density blockwork such as Aerated Autoclaved in some cases may not be compatible with a render mix having a cement:lime:sand ratio stronger than a 1:1:6 for example.
Applied render
Block manufacturers can advise on the recommended mortar/render strengths for the chosen block. Strength or classification of renders is detailed in the individual product literature in Section 10 of the Weber render solutions handbook.
Section through substrate requiring mechanical key
Concrete Concrete offers minimal suction and generally insufficient key for the rendering to adhere. The aggregate should be exposed during construction of the concrete, or after the concrete has cured by the use of bush hammering or other suitable mechanical means. Alternatively, the concrete should be coated with a weber.rend aid to provide key for the subsequent render application. No-fines concrete will provide a satisfactory key. Please note that advice should be sought regarding concrete curing agents that may interfere with the bond of the weber.rend aid application.
weber.rend aid key coat applied 2 – 3 mm and textured to produce a deep, heavy mechanical coat
Zone of mechanical key
Brickwork To provide key, new brickwork should be laid with the mortar joint recessed 10 – 12 mm by width and depth squarely. Existing brickwork will require the joints raking back to the above dimensions. If the joint is too hard, the key should be provided by a stipple coat of weber.rend aid. Some common bricks may contain deleterious sulphate salts. If possible, advice should be sought from the brick manufacturer regarding their use as a substrate for rendering in that location, particularly in high exposure or potentially damp areas. 30

Movement Control Weber renders are manufactured from carefully selected and graded aggregates to minimise drying shrinkage of the applied render. Providing that good practice, appropriate design and suitable preparation is undertaken, the rendering will be fully bonded to the substrate and restrained from movement by that surface and will not crack. It is therefore most important that stress/crack control is considered prior to construction of the substrate in order to reduce the likelihood of cracking.
2
To increase the spacing of movement joints beyond that recommended for reinforced masonry
When the construction is correctly divided into appropriate panels separated by suitable movement joints, the stresses caused by drying shrinkage and normal building movement will dissipate to the detailed relief joints. Movement joints are not a requirement in the render alone as this is fully bonded to the substrate. They should however, reflect and follow through from the relief joints detailed in the construction.
Movement joints Guidance on the placement of movement joints should be gained from the specified block manufacturer and used in conjunction with the BS EN 1996-2:2006 Code of practice for use of masonry and BS 6093:2006 Code of practice for design of joints and jointing in building construction.
3
In long panels where movement joints are impractical
The guidance given in these standards is that joints should usually be included at 6 m intervals and 3 m from corners, however, this will vary depending upon the type of construction and the strength of the brick or block. 3m
6m
movement joints
Mortar bedding joint reinforcement The exact spacing of joints can be adjusted by the use of mortar bedding joint reinforcement. The amount and positioning of this reinforcement should be detailed by the block manufacturer. In Weber’s experience cracking of the substrate can be considerably minimised if mortar bedding joint reinforcement is used, specifically:
1
At weak points in the construction, such as above and below window and door openings
Glass fibre mesh reinforcement The render’s ability to distribute and resist stresses can be enhanced by the inclusion of glass fibre reinforcement mesh cloth at positions of localised high stress i.e. at the corners of openings, at junctions of differing materials or around crack inducers such as weep holes. For more detail regarding the inclusion of mesh please refer to best practice recommendations in Section 9 of the Weber render solutions handbook. Straight line cracking that can sometimes be seen in completed render panels is not typical of render failure, but rather the reflection of a crack in the substrate. Stress/crack control must be given serious consideration prior to construction.

Machine Rendering Technology that makes current skilled personnel more productive is a distinct advantage. A machine application does just that. Tradesmen applying external renders must to be free to apply their skills to completing wall areas, not labouring to carry or hoist mixed material to the place it is needed. Modern machinery not only mixes and conveys the wet material in just such a way but also even applies it to the wall so that trades people have the opportunity to use their levelling and finishing skills to the full.
Advantages • • •
Self-contained diesel driven or Electric 400volt Designed for renders & plasters Can pump long distances 20 to 50 litres a minute (up to 60m dependent on height and material)
•
300 to 350m2 of finished work a week including preparation
• • • •
Batch mixers or Continuous mixer Accurate water control Uniform product consistency Material can be used direct from the pallet
•
Easy to clean
Sprayed roughcast finishes are made possible only with the machine application approach where panels are applied and finished within hours of starting - truly the fast track method of modern rendering. The UK and Irish market has been very traditional in approach and it has taken many years for a technology that is widely accepted on the continent to be adopted here. The pioneers though have now established the principles and more and more of Weber’s recommended applicators have made machine application the very core of their businesses. Several types of machine are on the market.

Training
Health and Safety
Weber, an international leader in the manufacture and application of innovative and practical solutions for both Facades and Construction, is pleased to outline its comprehensive training programme for Monocouche Renders, External Wall Insulation, and Concrete Repair & Construction Mortars. The product Training Manager has developed course programmes specifically to address the current needs of the industry. Scheduled courses are run monthly and a series of further in- depth specialist courses can be carried out by arrangement, Weber appreciates the importance of training and aims to bridge the skills divide by working closely with applicators and colleges etc.
The building industry is the most dangerous work environment bar none. Much effort has been put into improving the generally dismal historical record. As a responsible manufacturer Weber is constantly reformulating products to reduce possible risks to users and clearly states what risks are involved with all products. These risks only apply during application. Once cured, the products are non-hazardous in all respects. All materials carry Health and Safety labelling in a clear easily recognisable format as recommended by the HSE (Health & Safety Executive).
Monocouche Aimed primarily at those using Monocouche materials for the first time, this course explores the fundamental basics of good rendering practice along with the application and finishing techniques associated with these products. A one day course, it includes both theoretical and practical activity. Practical demonstration of machine application techniques are included as part of the course.
Lifting Even when labelled as non-hazardous, a practical, common sense approach to material usage is to be recommended. Weber materials manufactured in the UK are kept to weights of 25kg and below where possible. Lifting should be carried out with the back straight and upright with the load as close to the body as possible. Do not to cut corners by attempting to carry multiple packs above 25kg.
Essentially N0n-hazardous Our pastes, liquids and sealants are generally non-hazardous in use but may be difficult to remove when dry. The generic Health & Safety label reproduced here carries common sense precautions.

Basic Introduction to External Wall Insulation Increasingly popular as the technically superior method of achieving ever more stringent insulation requirements, External Wall Insulation (EWI) has a wide range of possible insulants, systems and finishes. This one day course provides an overview of the complete range of render protected EWI systems along with a guidance regarding the basic principles involved. Further weber.therm, system-specific courses are available by arrangement.
Cement based The HSE has identified the small amount of soluble Chromium VI that naturally appears in grey ordinary Portland cement as the element that stimulates an allergic dermatological reaction in some people that results in ‘cement burns’. Legislation now requires manufacturers to keep levels of soluble chromium VI below 2 parts per million of the total dry weight of the cement content. White cement/sulphate-resisting cement and cement fondu all have contents below this level and are naturally compliant. Ordinary Portland cement however needs to be treated to achieve these levels. All material supplied by Weber is either naturally compliant or has been treated to be compliant for the stated shelf life. Bags must be stored unopened, in clean dry conditions, off the ground and above 5°C. Use of treated products after the end of the declared storage period may increase the risk of an allergic reaction. Cementitious mixes may contain relatively sharp, often angular aggregates and are therefore generally abrasive when wet. Newly applied product is also very alkaline.
