Prestandafördelar

This admixture boosts bond stamina between the layer and substratum. It lowers cracking caused by thermal motion or drying out shrinking. The polymer enhances workability and extends open time throughout application. Finished surface areas show better abrasion resistance and lasting longevity. Water absorption drops dramatically, which assists protect against efflorescence and mold growth.

Rekommenderad dosering

Användning 2– 5% by weight of overall dry mix for conventional external wall putty. For high-performance skim layers, dosage might increase to 6%. Always test small sets first to verify efficiency under regional problems.

Hanterings- och förvaringsutrymme

Förvara i en fantastisk, torrt område borta från fukt. Håll påsarna förseglade när de inte används. Service life is one year if stored properly. Prevent exposure to guide sunshine or high moisture. Usage clean tools to avoid contamination. Sätt på handskar och ögonskydd under hanteringen.

Mer kraftfull, Smoother Wall Surfaces with Better Performance

RDP (Återdispergerbart polymerpulver) is a key active ingredient in premium exterior wall putty and skim layer products. When mixed right into the base material, it forms an adaptable polymer film after drying out. This film binds all bits with each other, making the finish a lot stronger.

Mycket bättre vidhäftning is one significant advantage. The putty sticks firmly to concrete, tegel, or plaster surface areas. It stands up to peeling off or splitting also under temperature level adjustments or moisture exposure. This makes fixings much less frequent and saves money and time over the long-term.

Water resistance improves considerably. RDP sänker vattenabsorptionen, which helps secure the wall from rain, fukt, and mold development. The surface area remains cleaner and lasts longer without blistering or powdering.

Workability obtains less complicated also. Contractors discover the mix smoother to use by trowel or spray. It spreads out equally and levels well, offering an uniform finish with less marks. Drying out time continues to be sensible– quick sufficient for following steps but not too fast to trigger problems.

Versatility issues outdoors. Buildings naturally move a little due to weather or resolving. RDP includes elasticity to the coating so it relocates a little without breaking. This prevents hairline fractures that usually appear in rigid surfaces.

For both new builds and remodellings, utilizing RDP-enhanced putty or skim coat supplies an expert result. It functions well on outside wall surfaces that face sunlight, vind, or rainfall daily. The final surface additionally accepts paint better, providing a cleaner look with enhanced sturdiness.

Producers select RDP due to the fact that it mixes conveniently with concrete, kalk, och fyllmedel. It does not need unique devices or processes. Simply include it to the dry mix, and the performance upgrades come immediately when water is added site.

5 FAQs of Concrete Admixture RDP Redispersible Polymer for External Wall Putty and Skim Coat

Vad är RDP och varför används det i väggspackel?

RDP stands for Redispersible Polymer Powder. It is a key additive in external wall putty and skim coat. När det blandas med vatten, den bildar en flexibel film som binder samman material. Detta förbättrar vidhäftningen, vattenbeständighet, and overall durability of the coating.

How does RDP improve putty performance?

RDP makes the putty stick better to walls. It also reduces cracking and powdering over time. The polymer film fills tiny gaps in the mixture, which blocks moisture from getting in. Som ett resultat, the surface stays strong and looks smooth even under weather stress.

Can RDP be used in both interior and exterior applications?

Ja, but it is especially valuable for external walls. Outdoor surfaces face rain, sol, och temperaturförändringar. RDP helps the putty handle these conditions without failing. For indoor use, it still adds strength and smoothness, though the demands are lower.

What happens if I skip RDP in my putty mix?

Utan RDP, the putty may not hold well to the wall. It can become brittle, crack easily, or wash away in rain. You might also see dusting or flaking after drying. Adding RDP ensures long-lasting results and saves repair costs later.

Hur mycket RDP ska jag lägga till i min mix?

The right amount depends on your base formula and desired performance. Vanligtvis, 2% till 5% i vikt av totala torra ingredienser fungerar bra. Följ alltid tillverkarens instruktioner. Too little gives weak results; too much may affect workability or cost unnecessarily.
