Resin Rock Powdered Concrete Additive

Stronger mix. Better grip. Just add water.

Resin Rock is a powdered polymer additive that makes ordinary bag-mix concrete and mortar perform like a professional-grade blend. It acts as both an adhesive and a bonding agent, so your mix sticks better, flexes more, and cures stronger. It does the same job as the liquid polymer additives sold at hardware stores, but in powder form, so you aren’t paying to ship water. One bag of Resin Rock can treat up to one 50 lb bag of cement.

Why You’ll Love It

• Better adhesion: Helps mortar grab onto surfaces it normally struggles with, including foam

• More strength: Makes standard bag mix much stronger and more durable

• More flexibility: Helps reduce cracking as your piece cures and settles

• Powder, not liquid: Lighter to ship and easier to store than bottled polymer

• Simple to use: Mix it right into your bag mix and add water

  
  

Perfect For

• Vertical concrete and faux rock projects

• Building lightweight stone bases and table bases over foam

• Carved, stamped, or textured concrete with embedded fossils and details

• Any project where you want a bag mix to bond and hold up better

  
  

How to Mix

Add your water to the bucket first, then add your mix until it’s soupy. Keep adding mix until you reach the consistency you want. Adding the powder to the water (not the other way around) keeps clumps from forming at the bottom.

Pro Tip: Concrete and mortar are porous. If you’re pouring resin over your finished piece, apply a seal coat and primer first to stop air from coming up through your finish.

Make concrete that holds up.
