Product Description
Weber Weberend One Coat Render Grey is a premixed sand and cement render which incorporates a polymer bonding aid for use in rendering brickwork, blockwork, and concrete, among other suitably prepared substrates. This is a pre-blended single coat application render and can be used for application to most suitably prepared brick and blockwork in conjunction with Weber decorative finishes for best results.

+ Delivery & Returns
- Features and Benefits :
- Resists the penetration of external water and has excellent weather resistance and durability, whilst allowing the structure to breathe
- Suitable for hand or machine application
- Incorporates polymers for increased bond strength
- Factory batched for consistency
- Scratch coat render
- Gives the same final appearance as a traditional sand and cement render mix but in significantly less time
- Can be used a base for a number of Weber decorative finishes
- Uses :
- Can be applied to most suitably prepared substrates, including: brickwork blockwork and concrete
- Provides an excellent background for all weber finishes, masonry paints and many other types of surface coatings
- Constraints:
- weberend OCR is unsuitable for application to gypsum plaster or surfaces that have been previously decorated. Seek advice before rendering onto common brick
- Preparation :
- All surfaces must be sound, clean, dry and free of any material which may impair adhesion
- Scaffolding must be independently tied to allow for uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration must be rectified.
- Poorly keyed surfaces, for example smooth concrete, or substrates of uneven or high suction should be prepared with weberend aid. Mask around the areas where material is to be applied. Masking tape must be removed before the material has dried out.
- Expansion joints should be included as required by the substrate and carried through all applied materials
- Note: In many cases rendering applied to expanded metal lathing is more prone to cracking than when applied to dense masonry. To reduce this risk, lathing must be fixed strictly in accordance with the manufacturer’s recommendations and relevant codes of practice
- Mixing :
- weberend OCR should be mixed with clean water at a rate of approximately 4 - 5 litres per 25kg bag using a tumble mixer or suitable drill with whisk attachment. For best results, use as little water as possible and mix to give a workable consistency.
- Note: weberend OCR may stiffen on standing. Re-mix product to regain workable consistency but do not add any more water.
- Application :
- To avoid dampness and discolouration of finishes rendering should be avoided below DPC or within 150mm of ground level. weberend OCR should be applied with a hawk and trowel in a one coat operation, then ruled level. On low suction backgrounds a first pass may be necessary prior to building up the full thickness in the second pass.
- Render thicknesses are as for traditional materials -:
- External render approx. 16mm for sheltered to moderate exposure or 20mm for severe exposure.
- Internal render approx. 8 to 19mm
- Tiling approx. 8 to 20mm.
- Thickness should not exceed 25mm.
- Finish as required. For plain face finishes rub up in the normal way as the render begins to pick up. Other appropriate fishes may be achieved by suitable means
- Curing :
- Cure for 2 - 3 days before over coating. During rapid drying conditions such as hot climates, curing with a fine spray of clean water may be necessary.
- Protect from unfavourable weather conditions during application and early curing
- Do not apply :
- If frost is forecast within 24 hours of use
- In damp/wet conditions
- In temperatures below 5 degree C or above 30 degree C
- On elevations in direct sunlight or where the substrate is hot
- Packaging + Coverage :
- weberend OCR is supplied in 25kg bags.
- When applied at 16mm thick, coverage is approximately 0.87m2 per bag.
- Note: These estimates take no account of wastage and will vary according to the type of surface involved and method of application
- Storage and shelf-life :
- When stored unopened in a dry place at temperatures above 5°C, shelf life is 12 months from the date of manufacture printed on the side of the bag
- Health Safety :
- Contains cement (Contains chromium (VI). May produce an allergic reaction. Harmful by inhalation. Irritating to eyes and skin. Keep out of the reach of children. In case of contact with eyes, rinse immediately with plenty of water and seek medical help. After contact with skin, wash immediately with plenty of soap and water. Wear suitable protective clothing, gloves and eye/face protection. Keep out of the reach of children
