Durability and Longevity
- Weather Resistance:
Quality render provides protection against the elements. It should be
durable enough to resist damage from weather conditions such as rain,
snow, sun, and wind. High-quality renders will not easily crack, peel, or
discolor over time, even under harsh environmental conditions.
- Waterproofing:
A good render often incorporates waterproofing elements or is designed to
prevent water penetration, which could otherwise lead to structural issues
like dampness, mold, or deterioration of the building materials.
- Crack Resistance:
A good quality render should have crack resistance, particularly for
external walls exposed to temperature fluctuations. It is designed to
expand and contract with the building, helping it avoid cracking and
ensuring long-term integrity.
