SURFACE CONDITION
For best project results, the concrete should be in sound physical condition, free of extensive cracking, pitting and spalling. The surface must also be dry and clean and free of dust, dirt, efflorescence, oil, chemicals, pevious flaking coatings and other contaminants which may block effective long-term adhesion.

REPAIRS
For best visual results and long-term performance, cracks, holes and significant surface pitting should be filled with a cement patch material and allowed to cure as directed before proceeding.

EXPANSION JOINTS
Expansion joints in the concrete slab serve an important purpose, guarding against cracking in the slab due to movement — and should NOT be filled. If covering the expansion joints is still preferred, joints should first be treated with ElastoLock Exterior Membrane and Elastolock seam mesh to minimize the chance of any cracking in the finish later due to slab movement.

SMOOTH SURFACES
Very smooth or "power troweled concrete" lacks optimal surface profile for most effective bond. In such cases, etching the concrete is recommended to ensure good penetration and "grab" of the coating. Etching will also remove efflorescence from the surface. If etching is required, see the surface preparation section for instructions on etching.

WASHING THE SURFACE
Removing all dirt, debris and other contaminants is key for ensuring long term beauty and performance. For easiest and best results cleaning with a pressure washer is highly recommended.

MASKING / DROP SHEET USE
Protect adjoining walls and other objects prior to starting work.

Good surface preparation is easy if performed with attention to a few key details. For best results, follow written product instructions. For detailed preparation information, a visit to the surface preparation section is also recommended.

PROCEED WITH APPLICATION OF YOUR DESIRED FINISH ONLY WHEN PREPARATION STEPS ABOVE HAVE BEEN COMPLETED.

Exterior Concrete Preparation

HardRock Deck & Dock Application

 

 

HardRock Deck & Dock is an easy two-step application that quickly adds beauty and decorative functionality to concrete surfaces — indoors and out. With your exterior concrete surface prepared as directed, proceed with the following application steps.

STEP ONE: Cut in along edges with a 4" paint brush and then roll on a uniform coat of HardRock Deck & Dock in 4 x 4 ft. sections as you progress using the specially recommended "HardRock Deck & Dock Roller." As you go, run the roller lightly over the wet material several times to "massage" the texture. Continue in the same manner until the surface is completely covered. Patchiness or minor imperfections in the finish will be concealed when the second coat is applied. Allow several hours between coats. Test the surface before walking on it.

STEP TWO: Roll on a second coat with the same roller in a perpendicular direction (if possible). This will fill imperfections from the first application and make the surface look uniformly attractive. Let the surface cure fully until the following day (24 hours) or longer in cool or very humid conditions.

Sealer: HardRock Deck & Dock generally does not require a top-coat of sealer for most exterior applications. However, if even greater protection is desired – especially for main entrance areas or for surfaces which will be subject to more demanding use or salting – HardRock Clear Coat Sealer is recommended.
