Brick Paver Sealing
I am amazed by the number of potential brick paver sealing clients who do not think it is necessary to prepare their paver patio, walkway, driveway, etc.. for sealing. Preparation of the paving stone surface & paver joints is a must for the proper performance and appearance of paver sealant.
The average cost of sealing brick paver patios in Ann Arbor & Saline is @ $1.00/ sq.ft plus the cost of prep work. Price breaks usually start after 1000 sq.ft and for driveways. The cost of prep work depends on the severity of the condition of the paving stones & paver joints. Just for an easy example, a 400-450 sq.ft ground level paver patio with a couple of steps into doorwall, may cost $650-750 for general power washing, sanding of paver joints, and sealed with an approved brick paver sealant. Severe paving stone & paver joint cleaning may increase this price range. Brick paver repair to sunken or settled areas are also an extra cost. Most of our brick paver patio restorations this year are running in the $600-900 range when you factor in touch-up repairs.
The paver manufacturers have a few steps & cleaners of prepping for sealing that is not always necessary, but the minimum amount of prep work is a general power washing of the paving stones & paver joints. If weeds, grass, mold, & moss are present, a more aggressive power washing will be necessary. After the brick pavers & paver joints dry, an approved paver joint sand needs to be swept in all joints. Polymeric sand is NOT necessary to use if sealing your brick pavers and actually is discouraged from doing by polymeric sand manufacturers.
After the paver joint sand is carefully swept in all joints, touched up with a wisk broom in tight areas, and blown off the top of the paving stones with a leaf blower, the brick paver sealant can be applied. An earlier post I had on brick paver sealing methods explains the pros & cons of different methods.
To insure great performance & appearance from sealing pavers, the prep work must be done to make sure the paving stones & paver joint's appearance is enhanced by the sealant. Sealing brick pavers is not cheap, and some prep work is necessary to make sure you get the results you are looking to get from your interlocking pavers.
