ZURICH, July 29 (Reuters) - Sika reported lower

half-year sales and profit on Tuesday as the weaker dollar

shrunk the construction chemicals maker's earnings when

converted back into Swiss francs.

The company, which makes products used to strengthen and

waterproof walls and floors, said its sales fell 2.7% to 5.68

billion Swiss francs ($7.08 billion) in the six months to June

30.

Analysts had forecast 5.72 billion francs, according to a

consensus compiled by Vara.
