Home improvement additive engineered to reduce cracking and strengthen plaster and render mixes, TDP Plaster and Render Fibres Additive. That reassurance matters when finishing external renders or patch repairs where hairline cracks spoil the finish. Is a 150g pack the right size for the jobs you usually do?
⚡ At a Glance
- • Crack Resistance: Reduces shrinkage and cracking in renders and lime-based plasters
- • Best for: Plasterers, builders and DIYers working on patches and external renders
- • Not ideal for: Smooth decorative skim coats where fibres would affect final texture
Fine fibres disperse quickly and evenly through plaster and render mixes to control shrinkage. A 150g pack treats six 25kg bags of plaster or 150kg of dry render mix.
Reduced cracking – Thanks to quickly dispersing fibres
Fibres add into the dry or wet mix and disperse quickly and evenly, forming a fine internal network that limits shrinkage stresses. Suitable for both hand-applied and mechanically applied plaster and render mixes.
Fewer hairline cracks develop as the mix cures, cutting the need for remedial repairs and improving long-term finish durability.
Easy to add during mixing – With simple integration to existing mixes
Designed to mix readily into one-coat plasters and render mixes without specialised equipment, the fibres spread through the batch to provide consistent reinforcement.
Mixing remains straightforward on site, so time spent blending is minimal while finish quality improves, even on patch repairs.
Efficient coverage – Thanks to concentrated 150g pack
A single 150g pack is formulated to treat the equivalent of six 25kg plaster bags or around 150kg of dry render mix, ensuring measurable coverage for small to medium repair jobs.
Pack size suits tradespeople and regular DIYers who need enough additive for multiple repairs without excess waste.
