nb. Subject to alteration due to technical developments.
| Sitework | Scaffolding must be independently tied, to allow uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified. |
| Site Conditions | Temperature range, 5 - 30 degrees centigrade. GoRend HBS must not be applied to frozen or thawing substrates. If the coating must be applied in adverse weather conditions, it is essential to protect both the working area and finish before and after application. |
| Substrate | GoRend HBS can be applied as a one coat render on medium density blockwork with normal suction. For aerated concrete and low density blocks apply onto backing of ProRend Prep or Lime Cement Primer. For high density masonry and concrete, apply onto backing of ProRend Prep. |
| Preperation | The background has to be supporting and free from dust, loose particles, damp and other pollution which can be of disadvantage to the bonding. Protect fresh render work against weather influences. |
| Application | Mix whole bags at a time to avoid separation of additives, mix with approx 5 litres of water to a homogenous, lump free mass, allow to stand for 5 minutes and mix again. Inconsistency in water content can cause colour variations. Apply GoRend HBS with a stainless steeltrowel or rendering machine. Rule level with an aluminium straight edge and spatula flat. When sufficiently dry, between 5 – 36 hours depending on drying conditions, scrape the surface to achieve a uniform colour and texture. Any areas left un-scraped will result in a difference in colour and texture. |
| Curing | Curing with clean water may be necessary during rapid drying conditions. |
| Variations | The chosen colour can differ slightly from the original sample or colour chart. This is due to varying factors including application conditions and background. Subsequent orders of different batches can also moderately vary for which we cannot be held responsible. |
| Health & Safety | Cement powder mixed with water releases alkali. Prolonged skin contact should be avoided to prevent irritation (use barrier cream if necessary). Eye protection is recommended. If gloves are worn, they should not be plastic/latex. |
Application
GoRend HBS coloured render is mixed with clean water and applied to new blockwork in 2 passes, “wet on wet”. GoMesh or ProMesh Grade 5 is embedded in to the first pass, around all apertures and stress points (fully meshed on lightweight block).
GoRend HBS is then levelled off, flattened and left to dry. Once the GoRend HBS has had sufficient time to dry (5-36 hours depending on weather conditions) it is then scraped back with a nail float, any loose scrapings brushed off and then left to fully cure.
You can also achieve a tyrolean finish with GoRend HBS using a hopper fed gun with compressor - see our video How To Machine Apply a Tyrolean Finish.

GoRend HBs is a 'monocouche' (one coat) exterior wall render that provides decoration and protection from the elements. Monocouche render comes pre-bagged, in factory-batched bags of dry powder. The terms' through colour render' and 'scraped finish render' are associated with monocouche as the dry powder includes colour pigments. Once the monocouche render is mixed and applied, colour is consistent throughout.
The benefits of GoRend HBS:
- Complete in one coat, two passes
- Through coloured, so no need for masonry paint
- Flexible and less prone to cracking compared to traditional sand and cement.
