This process, known as curing, involves a certain degree of shrinkage. Shrinkage refers to the reduction in size or volume of a material as it dries or cures. In the case of Sugru, this shrinkage occurs due to the evaporation of moisture and the crosslinking of its polymer chains.
But why does shrinkage happen in the first place? The amount of shrinkage experienced by Sugru can vary depending on factors such as temperature, humidity, and the thickness of the applied layer. Higher temperatures and lower humidity levels generally lead to more significant shrinkage. So if you find yourself using Sugru in a hot and dry environment, expect a bit more shrinkage than usual.
The recommended curing time for Sugru is 24 hours. During this time, it gradually hardens and shrinks. It’s crucial to give Sugru enough time to fully cure to ensure maximum strength and durability. Patience is key.
While the shrinkage of Sugru may pose challenges for certain applications, it is relatively minimal compared to other materials. Its unique formulation allows for some flexibility and elasticity even after it has cured, helping mitigate any potential issues caused by shrinkage.
To minimize shrinkage during the curing process, there are a couple of tricks you can employ. First, apply Sugru in thin layers rather than thick ones. Thicker layers tend to experience more significant shrinkage as there is more moisture to evaporate and polymerize. So take it easy and apply a thin, even layer.
Secondly, controlling the environmental conditions during curing can also help reduce shrinkage. Avoid extreme temperatures and try to maintain a moderate level of humidity. By creating a more controlled curing environment, you’ll have better control over the shrinkage process.
Additional Hardening Options for Sugru

One simple approach to enhance the hardness of Sugru involves blending it with other materials. By incorporating a small amount of fine sand or powdered glass, the resulting mixture gains increased abrasiveness and hardness. This technique is ideal for projects necessitating a rigid and robust finish, such as repairing outdoor equipment or fashioning DIY tools.
Heat acceleration:
If you desire a swifter curing time and a harder final outcome, heat can be your ally. Exposing Sugru to heat, whether through direct flame or a heat gun, significantly reduces curing time and promotes a firmer bond. Exercise caution to avoid overheating the Sugru, as it may result in discoloration or burning.
Applying pressure:
Applying pressure during the curing process is another technique worth considering. By clamping or compressing the Sugru between surfaces until it fully cures, air bubbles are eliminated, ensuring a compact and dense end result. This method proves particularly valuable for projects requiring high-strength bonds or the ability to withstand heavy loads.
Post-curing techniques:
To further enhance the hardness of Sugru, post-curing techniques can be employed. After the initial curing period, exposing the cured Sugru to extended periods of UV light facilitates cross-linking of polymer chains, resulting in a denser and tougher material. Outdoor applications benefit greatly from this method, capitalizing on readily available sunlight exposure.
