The prevention of latex inversion in saltwater cement compositions for use in subterranean formations by inclusion of a combination of latex stabilizers and associated methods of cementing. Saltwater cement compositions comprising saltwater, a cement, a latex, a first latex stabilizer comprising a surfactant having the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>R-O-(OCH2CH2)mXM<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R is an alkyl group having in the range of from about 10 carbons to about 20 carbons, m is an integer in the range of from about 10 to about 40, X is OSO3 or SO3, and M is a compatible cation, and a second latex stabilizer comprising an alcohol ether sulfate having the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>R1-O-(OCH2CH2)nOSO3M<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R1 is an alkyl group having in the range of from about 4 carbons to about 12 carbons, n is an integer in the range of from about 1 to about 10, and M is a compatible cation.
